Stage-wise care of bulbul chicks
Stage 1: Nestling – unfeathered
Characteristics: Bulbul chicks are born completely naked with their eyes closed and are completely dependent on their parents for warmth, food and care. Thermoregulation is poorly developed in new-born chicks and they need an external source of heat at all times. The chicks’ eyes open by the end of the first week. At the same time, the first pin feathers begin to erupt. Pin feathers rapidly erupt in the second week of the chick’s life and the chick is fairly feathered by the end of the second week.
Feed: The chicks are extremely delicate at this stage and must only be fed on soft and very easily digestible foods. The chicks are primarily fed protein-rich foods at this stage and their diet can comprise of soft boiled egg, green caterpillars and grasshoppers for the first couple of weeks of their life. [Feed only green caterpillars and grasshoppers and refrain from using hairy moth caterpillars as they can cause intense discomfort and damage.] Soft fruits like banana, chiku, melon, figs, etc. and some infant cereal, like Nestum which is without milk, too may be added to the diet.
A blend of egg and infant cereal may be made for the entire day and refrigerated but skinned and pureed fruits must be added fresh to every meal. The feed may be diluted a wee bit in the first week by adding fresh squeezed fruit juices – grapes and pomegranates are excellent for the purpose. The formula, especially when offering pureed fruits, is best fed with a syringe while pieces of caterpillars and grasshoppers may simply be offered using a pair of forceps.
OOnce the chicks have settled and are accepting the feed well, ¼ drop of vitamin and calcium drops must be added to at least 2 feeds a day to begin with and gradually increasing to ¼ drop in four feeds of the day by the end of the second week.
Probiotic supplements too may be added as per the chick’s requirements – a tiny pinch of powder added to 3-4 feeds should be adequate for a chick at this age.
The chicks do not require any additional water at this stage as they get the required amount through their feed. [Please refer to note on ‘Water and Hydration in the previous page for further details.]
Feeding quantity and frequency: Feeding must begin at about 6 am and continued till about 7 pm. The chicks must be fed every half hour in their first week of life and every 40-45 minutes in their second week of life.
A new-born chick may only have 0.1 ml of formula per feed, increasing to 0.2 ml of formula per feed by the end of the first week. The feed quantity would gradually increase to 0.5 ml of formula per feed by the end of the second week. Once the chick has had enough, it will cease to beg and must then be fed at the next feed. Over-feeding must always be avoided.
As a rough estimate, a chick will consume 2-3 ml of feed a day at birth and up to 4-5 ml of feed per day by the end of the first week.
The daily average of feed consumed would increase to roughly 8-10 ml by the end of the second week.
Special care: Naked nestlings require additional warmth throughout the day even when housed at room temperatures. The surrounding temperature must be maintained at approximately 104˚F – 106˚F for the first week and reduced to approximately 102˚F – 104˚F in the second week of the chick’s life.
As their skin is very tender, they must be kept on soft bedding – a lining of soft cotton cloth may be preferable to paper towels at this stage. Refrain from using fleece or cotton towels.
Stage 2: Nestling – feathered
Characteristics: The chicks are adequately feathered, covering the bulk of the body, at this stage. Colour markings which are indicative of the species, become prominent at this stage. Chicks develop rather quickly now and will be ready to attempt short flights in another two weeks. The chicks are quite active and strong by this stage and begin standing on their legs by the time they are a month old.
Feed: The chicks are given a similar diet but the food proportions vary. At this stage, the protein content (eggs, green caterpillars and grasshoppers) can be reduced to about 50% of the chick’s diet, while the proportion of fruits and cereal can be increased to 50%. Infant cereals may be completely discontinued gradually. Formula must nonetheless be pureed and fed with a syringe in the 3rd week but the chicks will now start accepting mashed fruits, while slowly introducing small pieces of fruit that can be fed with a pair of forceps or by hand.
½ a drop of vitamin drops and calcium drops must be added to three feeds daily. Probiotics too may be added if required – a pinch of probiotics thrice a day should suffice each chick.
Feeding quantity and frequency: The chicks may only be fed every hour in the 3rd week and every hour to an hour and a half in the 4th week as they will now be able to consume larger quantities in one go. Feeding must begin by 7 am and continued till about 7 pm.
Special care: External heat may be discontinued during the day [on warmer days or depending upon the environmental conditions where you live] in the 3rd week but will still be required at night. The ambient temperature may be maintained at 100˚F for the chicks at this stage. Thermoregulation also develops by this age and as the chicks are now also feathered, they retain heat a lot better. External heat may be totally discontinued in the 4th week but the chicks must nevertheless be housed in warm spaces at night.
Stage 3: Fledgling – dependent upon parents
Characteristics: The chicks fledge by the time they are a month old. Flying feathers develop with speed at this age and their bodies are thickly covered in insulating feathers, making the chicks look like puffballs.
Feed: The chicks will now readily accept small cut pieces of fruit: banana, apple, chiku (sapodilla), muskmelon, figs, grapes, etc.
Caterpillars may be offered whole while egg may be offered in small pieces.
Feeding quantity and frequency: A plate of chopped fruit and egg must be given to the chicks 5-6 times a day. The plate must be left before them to encourage eating on their own and fruit must be replaced every 2 hours. The chicks start feeding by themselves at this age and will be completely off hand-feeding within a few days of fledging. Intermittent hand-feeding must be continued for a week or two after fledging until they chicks are consuming an adequate quantity themselves. To encourage eating on their own, offer a plate of chopped food and draw the chick’s attention to it. To encourage independence, the plate must be offered to the chicks when they beg instead of offering pieces of fruit by hand – they learn to pick up pieces of fruit faster this way.
By the time the young birds are 6 weeks old, i.e. a couple of weeks after fledging, feeding may be reduced to 4-5 times a day. A plate of chopped fresh fruits may be offered to the birds early in the morning, mid-morning, early afternoon and late afternoon.
Older birds rarely eat after 5-6 pm – they prepare to return to their roosts at this time.
Hand-feeding must have completely ceased by six weeks of age. The chicks will also not require skinned fruit anymore. In fact, they must also be offered whole fruits (i.e., complete with the skin) so they can learn to choose and eat the choicest parts on.
Special care: The chicks must be shifted to an aviary at this stage as they need flight practice before release. The aviaries must also have a nest box for the chicks as they may prefer to roost in the box at night. Alternatively, they may be shifted indoors for the night.
The chicks don’t require any external heat at this stage but must nonetheless be given warm roosting spaces at night, at least until a week or two after fledgling. What they essentially need is something to block off the cool breeze at night until they are a little older. Older fledglings may now be allowed to sleep in their aviaries and may even prefer to just sleep on branches instead of going into nest boxes – ensure that there are some covered branches so the chicks learn to sleep under leaf cover.
Once the chicks start to eat by themselves, they will attempt to pick up anything brightly coloured that stands out against the background. Often, they will pick up and ingest their droppings for the first few days until they are able to distinguish between their dropping and actual food. Droppings must be picked up frequently to prevent this.
A bowl of fresh water must also now be available for the chicks at all times as they will now start drinking water. It is also a good idea to offer a big and shallow bowl of water for the birds to bathe in – they will certainly enjoy it during the summer months.
Stage 4: Fledgling – independent
Characteristics: The chicks are fairly self-sufficient at this stage. Primary flying feathers will have erupted by this stage and the chicks will have lost the excess nestling weight.
Feeding: The chicks will now consume an adult diet and must be given an assortment of foods. Wild picked berries and fruit must now be introduced to their diet – this helps them familiarize with the foods available in the wild.
Fresh food and water must be available for them at all times.
The birds must be offered a combination of whole fruit and some chopped fruit pieces. The whole fruit encourages the birds to learn to peck small pieces out of whole fruit as they will consume many fruits that cannot be swallowed whole.
Special care: The chicks are now completely independent and must be readied for release. The process of soft release begins at 16 weeks of age.
Stage 5: Sub-adult/Immature
The chicks will have undergone their first moult and will have their adult feathers by six months of age. Adult colour makings also start to appear now. The chicks must have undergone rehabilitation by this stage. If opting for a hard release, this is the right time to release them.
Stage 6: Adult birds
Adult bulbuls will be completely independent and should have completely stopped returning to the aviary. They will breed in the following season.
Rehabilitation and Release
The young birds must be must be shifted to an aviary at the time of fledging and given adequate flight exercise before release.
This is essential for them to develop the agility and swiftness required for survival. The aviary must be at least partially sheltered so the birds are not exposed to harsh sunlight throughout the day. Food at this stage must not be offered in one place but scattered around throughout the day so the young birds learn to search for it. Care must be taken to prevent the chicks from flying into the mesh and injuring themselves. Fresh drinking water and a larger shallow bowl of water to bathe in must be available at all times. The aviary must also have a couple of nest boxes, hung higher in the aviary, for the young birds to roost in.
The first step towards getting your bird ready for release is to break the young bird’s dependency on human beings and to give it maximum opportunities to be tuned in to its natural instincts. The process of rehabilitation must actively start by the time the chick fledges and followed meticulously until release.
Important things to be kept in mind when releasing bulbuls
1.
Place of release and the prevailing environmental conditions
Wherever possible, all rescued animals must be released where they have been picked up from. This is particularly important when releasing animals that had been admitted to care centres as adults so they can have the chance to go back to familiar and known spaces. Younger birds must be released in suitable locations with good tree cover and ample fruiting trees, and in locations where they will be easy to monitor for the first few days after release.
The only instance where release to the same location must be avoided is if there have been irreversible changes which led to the initial displacement of the birds in the first place and will have rendered the place unsuitable for the survival of the species.
2. Age and timing of release
Birds that have been admitted as sub-adults or adults may be released just as soon as they are ready to be released. The only consideration for them is fitness for survival.
Birds that have hand-raised, on the other hand, need to go through a more protective method of release. Young birds may be released at the age of about 2½ - 3 months when opting for a soft release whereas those that are being hard released must only be released after 4-6 months of age.
3. Method of release
Birds may be released by following protocols for either a soft release, which is most ideal and recommended for hand-raised young, or through a hard release.
Hard Release is a means by which the animal is released into a new location without its being accustomed to the new environment. This process is appropriate for bulbuls that have been taken into care as adults.
Soft Release is a means by which the animal is gradually introduced or familiarized to a new environment before its release into that location. Hand-raised animals are at a disadvantage of not having had adequate parental learning and require additional safety and protection during release; hence the ideal way to release them is through a process of soft release.
The simplest way to soft release a bulbul is by allowing it to fly in-and-out of its enclosure for the first few weeks after it fledges and becomes fairly independent. The young must be shifted to enclosures where they will be released from so that they can identify the enclosure and their surroundings – this will help in building site fidelity and make it easier for them to return to the safety of the enclosure until they are completely independent and ready to leave. The young birds may be allowed to fly out in a few weeks thereafter through a couple of openings/windows in their enclosures. At this age, the birds will not fly far and return to their enclosure several times during the day and most certainly to roost at night. The access opening and windows must only be opened at dawn and closed at night to prevent entry of predators like rats, cats, snakes, etc.
Once they have explored their surroundings and have found safe roosting spaces for themselves (typically in a few weeks), they will cease to return to the protection of their aviary but may return for titbits of food.
Eventually, they will become completely independent and cease to return to the aviary at all. Supplemental feeding must be continued until the birds are independent but may be ceased once the birds are self-sufficient.
BBirds may be released in a similar manner if hand-raising and rehabbing from home. Consider a small cagey extension out of any room or window – this system works best in apartment buildings. The extension may simply be a light frame with wire mesh if there is no threat of cats – this is inexpensive and very easy to install. The extension below has been used successfully and the birds were periodically let in the room to exercise their wings.
Experience suggests that birds released from homes return for longer durations as they may have stronger bonds with both the homes and the caregivers. They are also known to visit every now and then well after the gain complete independence. Do refrain from encouraging the birds to enter the house if the birds visit you.
Birds that are accustomed to entering the house are twice as likely to accidentally fly into someone else’s house and land into trouble.
Note of caution: A ceiling fan must never be used in a room with birds to ensure they don’t fly into a moving fan and get injured fatally.

Bulbuls
Hatchling (naked and may be blind)
Seek assistance from a more experienced rehabber. These guys can be difficult.
Nestling (pinfeathers or feathers, but not flying yet)
Vitamin C is an essential part of the bulbul's diet; it will most likely die if fed a straight formula diet or one with insufficient fruit.
60-70% DRIED formula and 30-40% fruit mixed and then warm water added to applesauce consistency. Fruit should be fresh mango, papaya, banana, or any combination of the three, but applesauce or strained fruit baby food can be used if necessary. Add two to three mealworms (preferably ones who've recently shed their skins - they are white) and small pea size pieces of soft tofu or bits of boiled egg for additional protein supplement. Protein is VERY important at this stage for proper feather growth, but don't substitute tofu and egg for formula. Bulbuls at this age should have two feedings per day of straight formula with a pinch of Tang added for Vitamin C. Bulbuls are more susceptible to poor feather growth from insufficient protein than mynahs are. Pinfeather babies should be fed every half hour through a twelve-hour period and feathered babies every 45 minutes to an hour through the same period.
Fledgling (limited and strong flight)
Same mix as above, but formula mix should be pudding consistency (add less water).
Three mealworms are okay for this age along with tofu and egg. One or two de-legged crickets can also be given. As the baby gets older, mix the formula to a thick paste consistency and start feeding off of a finger. This will help to transition the bird to solid food. After about three or so days of feeding the paste formula, bits of fruit or softened softbill pellets can also be given. Soft fruit can be given at a younger age, of course, but not to substitute for formula. Start putting pieces of fruit in the bird's cage along with insects and feed approximately every 1 1/2 hours. The bird can go up to 2 hours if you observe it feeding itself. Until it is actively interested in food, however, do not let it go over 3 hours without offering more food than what it has already in its cage. Some bulbuls may take an abnormally long time to wean, go very slowly and don't wean the bird cold turkey. When the bird is actively interested in food, transition over to an adult diet.
Adult
Because these birds are frugivorous, they must have a fairly constant supply of fruit in their diets.
Softbird pellets (8 in 1 makes a good pellet for softbills) should constitute about 40% or less if they are given a softbill insect crumble. Only four to five mealworms per day should be given, as healthy bulbuls tend to be on the plump side anyways. De-legged crickets can be given now and then; some birds are more interested in them than others. Soft tofu, and chopped, boiled egg are very good sources of protein. Mango is the most important food that a bulbul can learn to eat. Mango trees grow all over the island and provide an excellent fruit source. Fruit should make up at least 50% of the bulbul's diet and at least two different types of fruit, most important are mango, papaya, and banana, should be fed along with pellets, etc. Peeled, chopped grapes, watermelon, and chopped up strawberries are well-appreciated treats. Bulbuls to be readied for release should be fed food they can find in the "wild" such as mango, papaya, banana, cooked rice, bread pieces, and insects.

Red-cheeked Bulbul | Fauna
The red-cheeked bulbul, widespread in the southern regions of Asia, was brought by man to Australia and North America, where it successfully acclimatized.
Habitat.
Distributed in South Asia. Introduced to Australia and North America.
Habitat.
Native to Asia, the red-cheeked bulbul lives in areas with a warm climate: in Nepal, India and South China. Bulbuls are most likely to settle in gardens or next to fruit plantations. Some species live in open areas, others prefer dense forests. Bulbuls brought to Australia settled in the vicinity of Sydney and Melbourne, and in North America - in the state of Florida. nine0003
Species - Red-cheeked Bulbul - Pycnonotus jocosus.
Family - Bulbul.
Detachment - Sparrows.
Class - Birds.
Subtype - Vertebrates.
Do you know?
1. Almost all types of bulbuls are sedentary. Only birds that live in the northern regions of the range make seasonal migrations: offspring are bred in the north, and fly away to places with a warmer climate for the winter.
2. Not all bulbuls feed on trees: some species prefer to collect fruits, berries and insects right on the ground.
Those birds whose diet consists mainly of insects (for example, brown bulbuls of the genus Phyllastrephus living in Africa) feed mainly on beetles. nine0045 3. At the height of the mating season male bulbuls wake up with indomitable fighting fervor, and in the past people even arranged fights of these militant birds in the manner of cocks.
4. The yellow-bellied bulbul (Pycnonotus goiavier), which lives in the forests and clearings of Southeast Asia, is small, but brave to the point of insolence and watches everything that happens around with curiosity.
Lifestyle. nine0049 Reproduction. Red-cheeked Bulbul - Pycnonotus jocosus. Crest. The head is decorated with a crest of dark feathers.
Red-cheeked bulbuls are sociable and noisy birds leading a sedentary lifestyle. For the night, flocks of bulbuls settle in the crowns of tall trees, and at dawn they leave the night shelter and devote most of the day to searching for food, tirelessly calling to each other in sonorous voices. Their “vocabulary” is very rich, and some species even know how to sing.
During feeding, birds usually stay in flocks of three to five individuals, flying together from tree to tree and meticulously examining each branch in the hope of finding a juicy berry or a sweet flower bud. Birds most willingly eat the fruits of palm trees, plants of the laurel family and papaya, not disdaining overripe fruits that have fallen to the ground. Their varied menu also includes flower parts, nectar, spiders and insects, most notably ants. Outside the nesting season, when bulbuls live in pairs on jealously guarded home sites, rather large flocks of up to fifty individuals gather near rich food sources. Forest bulbuls are far from being so sociable, and during the day everyone hunts on their own, but at night they also gather in groups. nine0003
In the nesting season, which lasts from January to August, the male bulbul tirelessly sings his short songs, consisting of sonorous chirps and boisterous trills. In this way, he not only lures the female, but also notifies the neighbors that this territory is occupied and a nest will be built on it. At this time, the male becomes aggressive and does not tolerate the presence of rivals in his area, the area of \u200b\u200bwhich is from 4000 to 8000 square meters. Having created a pair, the birds build a cup-shaped nest from soft blades of grass, roots and other fragments of plants. The loose weaving of the walls of the nest allows rainwater to drain without accumulating in the tray. After mating, the female lays 2-4 light pink eggs dotted with brown specks. Both parents incubate the clutch in shifts for 11-12 days, and after the chicks appear, they diligently feed them with soft insects and fat caterpillars. After two weeks, the chicks leave the nest and switch to plant foods, although they still do not refuse parental offerings.
At three weeks old, juveniles fledge. In one season, an adult pair of bulbuls makes two or three broods. nine0003
