Chestnut-crowned Bush Warbler

The chestnut-crowned bush warbler (Cettia major) is a species of warbler found in South Asia. Although overall population size has not been quantified, this is one of the species that is declining due to habitat destruction. Although its population trend is observed to be decreasing, its decline is not happening in rapid fashion. For this reason, this is evaluated as least concern species. (Wikipedia, general species account).

The phylogenetic relationships among the Cettia species are shown below, based on the data by the Cornell Lab of Ornithology. It split from the Chestnut-headed tesia about 5 million years ago. Like many crows, this species is an adaptable, intelligent forager with a broad diet and strong bill. Crows commonly search on the ground as well as in trees, taking invertebrates, plant material and other available foods, and build substantial stick nests. Local habits should be interpreted from the species-level account above rather than assumed from the family alone (general Corvidae ecology).
