Crested Treeswift in Rajaji National Park

Soaring through the dense canopy of Rajaji National Park, a flash of grey catches your eye. It’s the Crested Treeswift (Hemiprocne coronata), a captivating aerial insectivore with a unique presence in the rich tapestry of the park’s wildlife.

A Master of the Skies

It belonging to the Tree Swift family is not to be confused with true swifts. While both excel at aerial acrobatics, the Treeswift has a more slender build and a characteristic long, forked tail. Adult males can be identified by their striking orange facial patches, adding a touch of color to their predominantly dove-grey plumage.

A Life on the Wing

Unlike true swifts who spend most of their lives airborne, it readily perches on high branches, scanning the forest for its next meal. Their sharp eyesight allows them to spot insects in flight, which they then snatch up with their agile beaks. Their diet consists primarily of flying insects like termites, dragonflies, and damselflies.

A Forest Dweller

It is a common resident breeder in the Indian subcontinent, including the verdant expanse of Rajaji National Park. They prefer open woodlands and deciduous forests, finding an abundance of insects and suitable nesting sites amidst the trees. These birds typically build tiny nests on exposed branches, using saliva and plant fibers to create a cradle for their single blue-grey egg.

A Secretive Nester

The nesting behavior of the Crested Treeswift is quite remarkable. The nest itself is so small that incubating adults have to perch upright on the edge, covering the egg with their underparts feathers. This unique posture ensures the egg remains warm and protected throughout the incubation period.

A Vital Part of the Ecosystem

A Symphony of the Skies

The dawn chorus in Rajaji National Park often includes the vocalizations of the Crested Treeswift. Their high-pitched calls, described as “kee-knew” or “kik-kik-kik,” mingle with the songs of other birds, creating a symphony of sound that fills the forest air. These calls serve various purposes, from communication between mates to territorial defense.

A Family Affair

It exhibits a cooperative breeding behavior. While the parents take turns incubating the egg, other members of the group, possibly offspring from previous broods, may assist in feeding the chick after it hatches. This social behavior ensures the chick’s survival and increases the overall breeding success of the group.

A Master of Camouflage

It plumage provides excellent camouflage amidst the foliage. Their predominantly grey upper parts blend seamlessly with the tree bark, while the white underparts offer countershading, making them less visible from below. This natural camouflage helps them avoid predators like hawks and falcons.

Threats and Conservation

The Crested Treeswift, although a common resident, faces certain threats. Habitat loss due to deforestation and degradation can impact their nesting sites and food availability. Insecticide use in agricultural areas bordering the park can also reduce insect populations, affecting their food source.

Conservation efforts focused on protecting forests and minimizing pesticide use are crucial for safeguarding the Crested Treeswift population in Rajaji National Park. Additionally, raising awareness about these fascinating birds can encourage responsible eco-tourism practices that benefit the park’s ecosystem as a whole.
