Mating and Nesting

The pair isolates during the flight by its own.
It builds up a cup-shaped nest in bushy vegetation which looks so messy. In captivity they are known to utilize boxes or baskets. In a thickly planted area it doesn't build a nest.
In captivity, a proper environment should be given for the bird to build nests. In wild the birds prefer living in dense vegetation and in forested areas. They build nest in bushy areas. Hence stones, bushy areas, tree branches can be formed inside the aviary for the bird.The females lay two to three eggs in a single clutch. Both male and female take part in building up the nest. Both are the active participants in incubating the eggs and in rearing the young.
Incubation process normally lasts for about 14 to 16 days and the chicks mature quickly once the hatching is done. From 2 weeks of the hatch the juveniles are ready to leave the nest. Successful rearing of chicks is very much dependent on the live food, meal-worms, small smooth-backed caterpillars, grasshoppers, maggots, woodlice and small locusts which are expected to be plenty.Two broods are normal for every breeding season. The chicks separate themselves from the parents as soon as they are capable to self feed or when they can defend themselves. The plumage of the juveniles is dull in appearance. The feather becomes darker as the bird grows and becomes mature.
Threats and conservation:
International Union for Conservation of Nature and Natural Resources (IUCN) has categorized Black crested Bulbul as 'Least Concern' since this species is found in wide range and is very common throughout its range. Also, the population of the species is increasing day by day. It is under the least concern category for consecutive years and is assumed that it will not reach the threshold of vulnerability. The threat for this bird is dependent on the hatching results. In few areas, the mortality of these birds happens owing to the deforestation happening in the dense forests.
