Distribution

The crested treeswift is a common resident bird in the Indian subcontinent. However, they are rarely seen in the central India and the east coast. They are resident in Yunnan province in southern China, Myanmar, Vietnam, Laos, Cambodia and Thailand.

Ecosystem and habitat

These crested treeswift species inhabit open woodland and deciduous forests. They are also found in scattered trees, groves, parks and gardens.

Diet and feeding habits

These crested treeswifts are insectivorous, aerial birds and catch most of their prey while flying. Their diet mostly consists of bees, wasps, ants, termites, flies and beetles. The treeswifts intermittently dart out from their perch to catch airborne insects and also glean insects from foliage. They have been found to drink by flying near the surface of water and pick insects from the surface of water.

Reproduction and breeding

The breeding season of these treeswift species is between December and April in India. There may be local variations depending upon the seasonal conditions. These treeswifts have been recorded to copulate both in-flight as well as on perch. The nest is small and is glued by saliva to the exposed branch of a tree. A single egg is laid and both the parents take turns to incubate. Both male and female provide parental care of the hatchling.

Movement and migration patterns

The crested treeswift species are resident birds. They may make local movements for feeding and breeding. Dispersal movements have been observed after the breeding season.

Conservation status and concerns

The global population of these treeswift species has not been quantified. The overall population trend is considered to be stable. It has extremely large range and hence considered not "Vulnerable" to extinction.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these crested treeswift species and has listed them as of "Least Concern".
