appears during the end of April or during May. Most pairs are double-brooded, which means they will have a second clutch in the same season. The second clutch appears in June to mid-August. The eggs are of a light blue-green color and have a similar shape to that of robin eggs. Typically, the clutch size is around 4–6 eggs. Every day, one egg is hatched. The hatchlings are born altricially. The eggs are incubated for 14 days, after which the fledglings move out of the nest onto a nearby tree or shrub. The parents keep feeding them for about a week. The immature crested mynas do not separate from their parents. They typically form small family groups and form a larger flock with others for feeding and traveling. Status and conservation Since 1998, the crested myna has been rated as a species of Least Concern on the IUCN Red List of Endangered Species. It has a range that is larger than 20,000 km2 and therefore, its range is too large for this bird to be considered vulnerable under the criterion of range size. Also, the population trends seem to be stable (over the last ten years or three generations) and so, this bird cannot be considered vulnerable under the criterion of population trends. Finally, it is believed that the population size exceeds 10,000 mature individuals and therefore its this bird cannot be considered vulnerable under the criterion of population size.
