What do bluebirds feed their babies
Out My Backdoor: Bluebird Family Life Isn't Always What It Seems to Be
By Terry W. Johnson
When we watch the nesting activities of the eastern bluebird, it appears that these beautiful birds live a pretty uncomplicated life style. However, researchers are finding that the private lives of these popular backyard birds often seem to be taken from the script of a daytime soap opera.
Bluebirds were long considered to be one of the 91 percent of all bird species that are monogamous. Such is not always the case, however. In one study, for example, 15 percent of adult females and 5 percent of adult male bluebirds were found caring for at least one nestling that was not their own. Another study conducted in South Carolina revealed that 5 percent of the bluebird pairs followed had multiple mates during the nesting season.
The chances of female bluebirds mating with more than one male were higher in locations with high population densities. By the same token, male bluebirds are more likely to attend to the needs of nestlings fathered by another male when their mates spend more time away from their nesting territory during the mating season.
Male bluebirds appear to have no problem caring for young sired by other males and don't show their own young any preferential treatment. Additionally, they tend to feed offspring more often than their mates.
Female bluebirds were found to feed male and female young equally. However are you ready for this? Many male bluebirds actually discriminate against male offspring! That's right, male bluebirds practice sex discrimination.
Here is what happens. During the first few days after bluebird hatchlings break out of the egg they are fed entirely by their mothers. During this time, male bluebirds supply their mates with small, soft insects such as caterpillars. The females, in turn, feed the protein-rich insects to the hatchlings.
Later, both parents forage for the steady stream of caterpillars, beetles, grasshoppers, crickets and other insects needed to satisfy the seemingly insatiable hunger of their rapidly growing young. It is during this phase in the development of the young that males begin a pattern of discrimination.
When the males return to their nests with food, they feed female nestlings twice as often as males. Consequently, during the 16 to 20 days the young remain in the nests, females receive considerably more food than their male nest mates. This gives them a better chance of surviving the rigors of the world once they leave the nest.
This discrimination extends well beyond the time the young fledge because both parents feed the offspring for up to a month after they fledge.
Nobody knows for sure why male bluebirds discriminate against male nestlings. Some biologists suggest this behavior reduces chances of male bluebirds having to compete with one of their male offspring for mates, nesting sites and food. Female fledglings may disperse up to 12 miles or more from the box where they are hatched. However, males often establish breeding territories within three miles or less of the cavity where they were raised.
But some experts question this theory, pointing out that female bluebirds seem to shy away from young, inexperienced males.
They appear to prefer more mature males experienced in providing for a nest full of demanding young. Older males also often do a better job of defending their nesting territory.
The family life of the bluebird is just one example of the fascinating true-life dramas taking place in the natural world. If you want to enjoy truly compelling drama, turn off the television, step outside your backdoor and carefully watch and listen. Who knows? You may find you don't need that new big screen television after all.

Bluebird Parental Care of Hatchlings, Nestlings, and Fledglings
Bluebird eggs hatch within a period between 24 to 50 hours. Chicks hatch blind and naked.
Both parents take care of the young and feed them with a diet rich in proteins, mostly insects.
Nestlings grow fast and leave the nest in about 16 to 25 days, depending on the region. After they fledge, parents continue taking care of the fledglings for about three weeks until they become independent.
How long does it take for bluebird eggs to hatch?
The incubation period is variable within the Bluebird’s ranging between 11-19 days with an average of 13.5 days. Bluebirds in the warmer southern states have slightly shorter incubation periods than those in colder northern regions.
The female Bluebird starts incubating the eggs on the last or day before last she lays the last egg. She lays one egg every day but does not sit on them.
The female does all the incubation of the eggs. Once the egg hatch, she broods the nestlings continuously until approximately day 5-7 after hatching, when the nestlings begin to have some thermoregulatory control over their body temperature.
The male is always around, bringing food to the female while she incubates the eggs.
Then, the male also brings food for the brooding female and the nestlings during the first days after hatching.
Egg hatching
Hatching begins 1 to 6 hours before the chick emerges completely from the egg.
The female incubates all the eggs for about the same period of time, ensuring that eggs hatch as close to each other as possible, eliminating the size advantage of chicks that hatch first over those that hatch last.
Blind and mostly naked.
Bluebird chicks at hatch are blind and mostly naked with patches of gray down. They weigh approximately 2.4 gr (0.08 oz).
Baby bluebirds are “altricial,” which means that nestlings are entirely dependent on their parents until they become nutritionally independent and can find food for themselves.
Both parents work equally to feed the chicks.
Both parents feed the chicks from day one, but the male does most of the work during the first five days after hatching. As in other birds, chicks open their mouth wide when they sense one of the parents in the cavity.
Studies of the breeding biology of nesting bluebirds indicate that both parents take about the same number of trips in and out of the cavity.
The same studies noted that the female alternates feeding with brooding the young birds during the first week as they cannot regulate their body temperature.
After a week, the young birds can regulate their body temperature, and the female does not have to brood them all the time, although she spends the night with them.
Parents appear to take more feeding trips and be more active during the early morning hours. The feeding continues in the afternoon but not as frequently as in the morning.
Foods fed to nestlings.
The parents bring crickets, spiders, grasshoppers, butterflies, and moth larvae, as well as berries such as raspberry, mulberry, dogwood, cherry, and honeysuckle.
The diet of nestling bluebirds is high in protein, consisting of approximately 68% invertebrates and 32% berries. A high protein diet helps chicks grow as fast as possible and leave the nest soon.

Nest sanitation.
Four to 5 chicks defecating in a small cavity would make a big mess, but both parents clean up the cavity throughout the day.
As it occurs in many birds, right after chicks are fed, these turn around to present the parent with a fecal sack or pellet. The fecal material is encased in a bag-like gelatinous packet the parent takes with its beak and drops far outside the nest.
When the chicks are very young, parents will eat the fecal sacks, but this practice ends as the chicks get older and are fed various food items.
If one of the chicks dies, one of the parents, when possible, pulls it out of the cavity and drops it outside the nest.
How fast do nestling bluebirds grow?
Bluebird chicks develop fast. After hatching, young bluebirds begin making calls loud enough to be heard when parents arrive with food.
Photo: Putneypics/Flickr/CC by 2.0Feathers begin to grow and replace the gray down by day 2.
The nestlings open their eyes by days 5 and 6. By day seven, the chicks have short feathers on most of the body’s back and sides. By day 13, chicks are completely feathered.
By day 13 and older, male and female young bluebirds can be told apart based on their plumage color.
Leaving the nest comes next.
As with the onset of the breeding season, the age at which chicks leave the nest varies with latitude.
Bluebirds in northern portions of the species range start nesting later, take slightly longer to hatch, and appear to take a little longer to leave the nest than birds in southern states.
However, the difference is small.
Across the species range, young Bluebirds leave the nest between 16 to 21 days after hatching.
Because all chicks hatch at about the same time, size differences among chicks seldom develop. Chicks of the same age and size leave the nest simultaneously.
Parental care after fledging.
Parents and young bluebirds stay together after fledging for about three weeks.
After leaving the nest, young Bluebirds remain in a relative hide for the first week or so. The parents bring food to the fledglings, which are easily located by their persistent calls.
During the first week after leaving the nest, fledglings still depend entirely on their parents for food. They begin practicing flying from place to place.
After the first week, the young birds begin to follow the parents to more open spaces. The young Bluebirds also start performing the typical sit-wait-and-drop strategy to catch invertebrates.
As fledglings gain experience obtaining their food, the parents feed them less and less.
Once fledglings become nutritionally independent, they take trips further and further from the family unit after about three weeks.
Then, the young bluebirds join flocks of juvenile birds that move about in the region.
Field observations have noted that chicks hatched late in the summer may remain with the parents through the winter.
Overall, the time it takes for young Bluebirds to separate from their parents is variable.
Some fledglings stay in the family’s territory for a long time, while others join flocks of juvenile birds and leave the family unit in about three weeks.

In the event that one of the parents dies, what will happen to the eggs or nestlings?
The effect on the eggs or nestlings varies depending on when and whether the male or the female goes missing. This is because the male does not incubate the eggs nor brood the young.
Disappearance when the pair has eggs in the nest
When one of the parent bluebirds dies or disappears during the egg-incubating period, the nest fails, and the remaining parent is likely to find a new mate and start another nesting attempt. Males do not incubate eggs, and the female cannot incubate, brood, and feed the young without the help of a male bringing food to the nest.
Disappearance when the pair has nestlings
When a parent dies or disappears when they have nestlings, the possible outcome depends on the age of the young bluebirds.
Generally, the remaining parent will try to get a replacement mate to help raise the brood.
Possible outcomes include:
- If the female disappears when the nestlings are less than 7-8 days old, the nestlings are likely to die because they are unable to thermoregulate their body temperature. While the male will continue feeding them, he does brood them at all. If the female disappears after the 8-12 days, the nestlings do not need brooding, and the male alone is likely to raise the brood on his own.
- If the male disappears when the nestlings are less than 7-8 days old or older, the female may be able to raise them alone, although she could fail.
Both the widowed male or female can enlist the help of a new partner that helps them raise the young. The new partner’s interest is acquiring a territory and having the next brood as a parent. New partners that begin as helpers do help but not as energetically as if they were the real parents of the brood.
Helping a widow raise his/her young is a way for “floaters” to acquire a territory.
A floater is an adult bluebird ready to breed but does not have a mate or territory.
Older siblings may help parents raise the new brood
Another observation of these studies was that young birds of the previous brood, still in the parents’ territory, may help feed their younger siblings.
This behavior appears not to be common and happens more often in certain habitat types and conditions than in others. The actual help older fledglings provide is also in doubt. It may be that young birds do this as a manner of practicing for when they become parents.
If one of the parents disappears and older fledglings are around, they are likely to help raise their younger siblings.

Birds feeding chicks
Birds skillfully catch big succulent insects in order to feed their cubs. This compilation captures caring parents feeding their little chicks. The photos are very touching and beautiful. Just imagine how much work this garden warbler in the photo below needs to feed 5 hungry mouths :)
And this robin is easier, she has only one chick, the rest apparently fell out of the nest, as often happens. She has already managed to find a great treat for him in the form of a fat caterpillar
Another caring mother who caught an insect similar to a cricket for her chicks
And this bird caught a worm and decided to feed all her cubs with it. Everyone got a piece of the delicacy
The most beautiful picture of a sunbird feeding offspring on the fly
Already quite an adult chick demands food from its mother :)
And this photo looks like a painting by some famous artist, the feeding process turned out to be very picturesque
And these baby swallows look not only hungry, but also aggressive - perhaps the parents hunted too long .
..
A mother flamingo takes special care of her chick, checking to see if food has gotten into her pet's beak. Reminds me of spoon-feeding :)
This heron has almost nursed her offspring, very soon they will go on their first flight
This bird looks like a hummingbird, but in fact it is a hook-billed thymelia and another skillful shot of feeding on the fly. Everything happens in a fraction of a second, and the photographer managed to capture this moment.0003
And here's a funny photo I decided to leave to complete the selection - a warbler feeds a chick, which has long outgrown the size of its parent's nest. In fact, this is a cuckoo chick that just threw it into the nest of a strange bird

What birds are the rarest in Russia and in the world. Brilliant real kotinga April 1 is celebrated in our country as the International Day of Birds. Interestingly, Russia is the habitat of many of them, including very rare ones. In our country, the rarest birds are protected by the state and are listed in the Red Book. Some of them live in sanctuaries and reserves. In this article, we will look at 10 endangered bird species.
Owl
This is one of the largest owls in the world, with a wingspan of up to 190 centimeters. In recent years, its population in our country has been sharply declining.
These rare bird species are predators. Eagle owls hunt snails and small rodents at night. They can also prey on small birds, although they prefer stationary prey. It is noteworthy that each representative of this species has its own territory, where he gets his own food.
Eagle owls are excellent and are used for catching rabbits, partridges and even hares.
But for the hunter it is a great success to find this bird. In addition, the eagle owl can be dangerous for the person himself.
Lesser swan
These are very rare birds from the Red Data Book of Russia. The small swan lives only on the territory of our country, it is one of the rarest birds in the world. He settles on Vaigach, in the tundra, as well as on Novaya Zemlya. The bird has a wingspan of up to 195 cm. An amazing feature of the small swan is the black beak, as well as white plumage. Birds feed on plants, eat grass, berries, and potato tubers. But sometimes they can also catch small fish.
At the age of 3, swans form pairs that last a lifetime. They build nests in spring on dry small hills, while some nests that remain after a pair can be used by other swans for several years.
Black stork
This is a very rare bird listed in the Red Books of Belarus, Russia, Kazakhstan and Ukraine. He lives in the forests in the Far East and the Urals.
Most of the birds live in the Primorsky Territory of our country. Since this is a very secretive rare bird, whether it will fly to some other region from here or not, it is not known for sure - their way of life has been studied very poorly. The black stork prefers to settle near lakes and marshes on the plains. Birds eat fish, catching it in reservoirs, and during the wintering period they can also eat small rodents.
Surprisingly, they choose a partner for life. They start breeding at three years old. Nests are built on rocks or tops of old trees, away from people. Storks feed their young 5 times a day. In the third month, the chicks fly away from their nest.
Mandarin Duck
This is a small duck with a characteristic orange coloration. She lives in the East Asian region, mainly in the Sakhalin region, on the Amur, etc.
Tangerines choose mountain rivers for life, because they keep well on the water and swim. Unlike other tangerines, they do not like to dive and do it only if they are injured.
Another interesting feature of the birds is that they love to sit on rocky ledges and tree branches, while other ducks rest in the water.
In our country, they are dying out because of raccoon dogs, which often ruin their ducks, and also because of hunting, although today it is completely prohibited.
Steller's sea eagle
These rare birds are rarely seen outside Russia, they fly out only occasionally for wintering. The Steller's Sea Eagle is one of the heaviest and largest species of eagles, weighing up to nine kilograms. In our country, it lives on the coast of the Sea of Okhotsk, as well as on the Kamchatka Peninsula.
It got its name for its amazing coloration: white covering middle wings of a bird. The bird is a predator that feeds on fish, mainly salmon. In addition, the eagle can catch Arctic fox, hare, seal, and periodically feeds on carrion. Birds settle on the coasts of the seas, while nests are arranged on the tops of trees and in river valleys.
Steppe kestrel
These rare birds were included in the Red Book of our country. lives in the south-west of Russia, as well as in the south of Siberia. This is a predator that feeds on insects, periodically scorpions also enter its diet. Birds hunt in flocks in the steppe open areas.
Periodically in the spring, the kestrel may prey on small rodents. In the 1st or 2nd year of life, birds form pairs that grow offspring for one season, then they change partners. Arranges nests on slopes of hills, in deepenings of rocks. Such a nest is a small depression, while the female does not use any materials to strengthen it, she simply digs a hole. After 28 days, the chicks hatch, and after the same period of time they fly away from the nest.
Demoiselle Crane
These rare birds are the smallest crane species. Birds live in six regions of the world, including Russia. In our country, they mainly settle on the territory of the Black Sea coast. They live in open areas, which also distinguishes them from other types of cranes that inhabit the swampy area.
Demoiselles form a pair for life, and if the offspring does not appear in the pair, it breaks up.
Demoiselles build a nest right on the ground. To do this, they dig a hole, after which they strengthen it with branches. Through 29days the chicks hatch.
Pink pelican
These rare birds live on the islands of the Sea of Azov. The pink pelican has been listed in the Red Book as an endangered species.
This is a fairly large bird known to the people as a woman bird. She feeds on fish, catching them with her beak. Pelicans do not know how to dive and only dip their beak into the river, catching their own food.
The main reason for the disappearance of pink pelicans in our country is the use of pesticides - they are contaminated with water bodies and soil. In addition, the area of \u200b\u200bsettlement of birds is decreasing, since people are actively draining water bodies, and without them, the life of pelicans is impossible.
Ivory gull
Ivory gulls are rare birds (photo can be seen in this article), which are listed in the Red Book of our country.
They live mainly in the Arctic, on Victoria Island, and one nest was also found on the coast of Novaya Zemlya. The bird is in danger of extinction. Tracking their population is very difficult as they are often migratory and few in number. White gulls are nomadic birds. In autumn, they sometimes migrate south, although they prefer to stay in the same areas of the North for wintering.
They form pairs only for one season in the spring. For nesting, they settle in whole colonies. The male and female take turns incubating the eggs for a month. The chicks are covered with down during the first year, only by the end of it do plumage begin to appear.
Red-legged ibis
Such rare birds, the photos of which are presented in this article, live in the Far East. This species was included in the Red Book of our country as being endangered. The population of red-legged ibis was numerous in the 19th century, after which the species began to decline rapidly.
In Japan, this species was declared extinct, in our country a pair of ibis was last seen in 1990.
Therefore, it is not known for sure whether this bird currently lives in Russia. But scientists are trying to find the remains of the population, in addition, to organize nature reserves.
April 1 is International Bird Day. Russia is a habitat for many species of birds, including very rare ones. In our country, they are listed in the Red Book and are protected by the state. Some of them live in reserves and sanctuaries.
Owl
The common owl is one of the largest owls in the world. The wingspan of this bird is from 160 to 190 centimeters. Its population in Russia has been sharply declining in recent years.
Eagle owls are predators, they hunt small rodents and snails at night. The eagle owl could just as easily hunt a small bird, but prefers motionless prey. Interestingly, each eagle owl has its own territory in which it obtains its own food.
Eagle owls are excellent birds of prey, they are used to catch partridges, rabbits and even hares.
However, it is very rare for a hunter to find such an owl. And besides, it can be dangerous for the person himself.
The bird is very fast and is capable of full speed from the moment it leaves the ground.
Now the number of eagle owls around the world is beginning to increase, Germany has achieved significant success in this, but in Russia their population is declining.
Black stork
The black stork is a very rare bird. It is listed in the Red Books of Russia, Belarus, Ukraine and Kazakhstan. It lives in forests in the Urals and the Far East. The largest number of birds lives in the Primorsky Territory of Russia. Black storks are very secretive, so their way of life is little studied. They prefer to settle on plains near swamps and lakes. Storks feed on fish caught in water bodies, and during wintering they can even feed on small rodents.
Interestingly, these birds choose their partners for life, starting to breed at the age of three. Black storks build nests on the tops of old trees or on rocks, far from the area where people live.
After hatching, storks feed their cubs 5-6 times a day. In the third month, the chicks fly out of the nest.
It seems that the difference between the black and the common stork is only in color, but this is not so. Birds have a different culture of interspecific behavior. In zoos, they have repeatedly tried to cross black and white storks, often the male even began to care for the female. As a result, all these experiments failed, since these birds have different mating rituals.
The largest population of black storks lives in the Zvanets nature reserve in Belarus.
Small swan
Lesser swan lives only in Russia, it is one of the rarest birds in the world. He settles in the tundra, on the islands of Vaigach, Kolguev and also on the Novaya Zemlya archipelago. The small swan has a wingspan of 170-195 centimeters. An interesting feature of the bird is the black beak with white plumage. Swans feed on plants, they can eat berries, grass, potato tubers. However, sometimes a small swan can also catch small fish.
Swans at the age of 2-4 form pairs that last a lifetime. They build their nests in the spring on small, dry hills, and some of the nests that remain after a pair can be used by other swans for many years.
The chicks are born a month later, and as soon as they hatch from the nest, the parents take them to the nearest body of water. And already after 45 days, young swans begin to fly. This period passes in small swans much faster than in swans of other species. Now in Russia, work is underway to restore the population of small swans. They are also listed in the Red Book of Russia.
Tangerine
The mandarin duck is a small duck whose male color is distinguished by its characteristic bright orange color. It lives only in the East Asian region, in Russia mainly on the Amur, in the Sakhalin region, etc.
Tangerines love mountain rivers, they swim well and stay high on the water. At the same time, unlike other types of ducks, mandarin ducks do not like to dive and do this only when they are injured.
Ducks feed on various seeds, algae and acorns. However, with a lack of food, they do not disdain shellfish and fish caviar. Tangerines nest in hollows of trees, in forests, which are located next to a mountain stream. Chicks are born after a little over a month. Moreover, the chicks fall out of the nest without the help of their parents and master the flight.
A characteristic feature of mandarin ducks is that they like to sit on tree branches and rock ledges, while other ducks prefer to rest sitting on the water.
In China, tangerines are popular, a pair of tangerines represents fidelity, they are called "yuan". The figurines of these ducks decorate the wedding room, it is believed that they bring happiness in marriage and fidelity of spouses.
Mandarin ducks are dying out in Russia because of hunting for them, as well as because of raccoon dogs, which often destroy the nests of ducks. Now hunting for them is completely prohibited, and the tangerines themselves are under the supervision of scientists.
Lesser kestrel
The steppe kestrel is listed in the Red Book of Russia and lives in the south-west of our country and in the south of Siberia. The kestrel is a predator, it feeds on caught insects, sometimes even scorpions enter its diet. Birds hunt in flocks in open steppe areas.
Sometimes in the spring, the prairie kestrel may begin to hunt small rodents. In the first or second year of life, kestrels form pairs that raise offspring for one season, after which the birds change partners. The steppe kestrel nests in the recesses of the rocks, on the slopes of the hills. This nest is a small depression, and the female does not use any materials to strengthen the nest, she simply digs a hole. On the 28th day, the chicks are born, and after another 28 days, during which their parents feed them, the steppe kestrel chicks fly out of the nest.
In recent years, the number of these birds has declined sharply, the steppe kestrel has disappeared from many habitats.
The fact is that birds have suffered greatly from human activities. The steppe kestrel feeds mainly on insects, and pesticides are widely used on the farm to control pests, which, if they do not kill the insect, then remain in its body. In the Red Book of Russia, the steppe kestrel is marked as a bird that is endangered.
Steller's sea eagle
The Steller's sea eagle is rarely seen outside of Russia, it flies out only occasionally for wintering. This is one of the largest and heaviest species of eagles, its weight can reach 9 kilograms. In Russia, it lives on the territory of the Kamchatka Peninsula and on the coast of the Sea of Okhotsk.
It got its name from its unusual coloration: its middle wing coverts are white. The Steller's sea eagle is a predator, it feeds on large fish, especially salmon. Also, the eagle can catch a hare, arctic fox, seal, sometimes it feeds on carrion. Steller's sea eagles settle along the shores of the seas, and nests are built on the tops of trees.
Sometimes nests are located in river valleys.
The eagle is a cautious bird that is reluctant to make contact with people. Therefore, there is very little information about the reproduction of this bird. Now the Steller's sea eagle is listed in the Red Book of Russia. Birds suffer greatly due to the constant increase in the number of tourists, as the eagles stop nesting in their usual territories. There are known cases of destruction of Steller's sea eagle nests by humans.
Various measures are currently being taken to protect Steller's sea eagles and increase their population.
Demoiselle Crane
The demoiselle crane is the smallest species of crane. They live in six regions of the world, including Russia. In our country, they settle mainly on the territory of the Black Sea coast. They prefer to live in open areas, unlike other types of cranes that inhabit swampy areas. Demoiselle cranes also form a pair for life, but if offspring do not appear in a pair, then it breaks up.
The belladonna's nest is made right on the ground by digging a small hole and strengthening it with small twigs. After 29days the chicks hatch.
It is interesting that not only the female incubates the eggs, demoiselle cranes take turns incubating their offspring. When attacking a nest of dogs or foxes, cranes together protect future offspring, sometimes other pairs of cranes can come to their aid.
Two months after hatching, the chicks can already fly. Demoiselle cranes are migratory birds, they go to winter in Africa and India.
Life expectancy of belladonnas in the natural environment is not exactly known, approximately 30 years. However, in captivity, some individuals can live up to 67 years.
Ivory Gull
Ivory Gull is listed in the Red Book of Russia. It lives mainly in the Arctic; in Russia, the white gull lives on Victoria Island and is endangered. Also, one nest was found on the coast of Novaya Zemlya. It is very difficult to track the population of white gulls, as they are few and often migrate.
White gulls are nomadic birds. They occasionally migrate south in the autumn, but prefer to stay for the winter in the same northern areas.
Seagull pairs form in the spring and only for the season. They nest in whole colonies for nesting. During the month, the female and male take turns incubating the eggs. During the year, the chicks are covered with down, only by the end of the 12th month they have plumage.
Ivory gulls feed on carrion, marine invertebrates, and excrement of seals and polar bears. Seagulls can swim, but most readily move on the earth's surface.
Pelican pink
The pink pelican lives on the islands of the southeastern part of the Sea of Azov, in the delta of the Volga River. The pink pelican is listed in the Red Book of Russia and is listed as an endangered species.
This is a fairly large waterfowl, popularly known as the baba bird. The pelican feeds on fish that it catches with its beak. Pelicans do not know how to dive and only plunge their beak into the river, catching their food.
From the second year of life, pelicans form pairs, which unite in colonies. For 2-3 days, the female of the pink pelican equips the nest, while the male helps her, bringing grass in his beak, which he often steals from his neighbors in the nest. On the 26th day, the chicks hatch and live without plumage for about two more months. On the 70th day they fledge.
The main reason for the disappearance of pink pelicans in Russia is the use of pesticides that contaminate the soil and water bodies. In addition, the area of their settlement is decreasing, as a person is actively engaged in draining water bodies, without which the life of pelicans is impossible.
Red-legged ibis
Red-legged ibis lives in the Far East region of Russia. This species is listed in the Red Book of Russia and is endangered. Back in the 19th century, the population of red-footed ibis was numerous, but the species began to decline rapidly.
In Japan, this species was declared extinct, but in Russia, a pair of ibis was last seen in 1990.
It is not known whether this bird lives on the territory of our country at the present time. But scientists are trying to find the remains of the population and organize reserves.
Red-legged ibises inhabit swampy rivers and feed on small fish and reptiles. Also, the ibis is considered a monogamous bird, ibises find a mate at the age of about two years and remain faithful to their partner all their lives. The eggs are incubated by both parents, on the 28th day the chicks are born. Until autumn, the chicks and their parents live in a common nest, after which they unite in flocks.
In addition to the Red Data Book of Russia, the red-legged ibis is included in the Red Book of the World.
The ecosystem today depends on birds. They contribute to the uniform distribution of seeds, carry pollen, and protect plants from harmful insects. In addition to helping the ecosystem, birds have amazing beauty, grace and funny habits. Scientists conducted research aimed at identifying the rarest birds around the world.
The journal Current Biology published a list of the rarest birds, research work was carried out by specialists from Yale University and the London Zoological Society.
Rare bird species
Unfortunately, some representatives of the list of rare birds are really on the verge of extinction. Poaching, unsuitable weather conditions, lack of habitual food - all these factors have a detrimental effect on the increase in the population. .
So, the most rare birds today include:
- wondrous spatula;
- Indian bustard;
- Brazilian merganser;
- frigate bird;
- fired;
- Honduran emerald;
- kakapo;
- blue-browed momot;
- Indian hornbill;
- red-footed ibis;
According to researchers, these representatives are considered the rarest on the planet. Many are on the verge of extinction, but they all have amazing beauty, unusual appearance and very rarely catch the eye of a person.
Breed description
