Long-tailed Shrike - Behaviour and Ecology

Behaviour and Ecology

This bird has a characteristic upright "shrike" attitude when perched on a bush, from which it glides down at an angle to take lizards, large insects, small birds and rodents. They maintain feeding territories and are usually found single or in pairs that are well spaced out. Several members have been observed indulging in play behaviour fighting over perches. The usual calls are harsh grating and scolding calls, likened to the squealing of a frog caught by a snake. They are capable of vocal mimicry and include the calls of many species including lapwings, cuckoos, puppies and squirrels in their song. This singing ability makes it a popular pet in parts of southeast Asia.

Long-tailed Shrikes take a wide variety of animal prey. On occasion, they have been noted capturing fish from a stream. They also take small snakes. It sometimes indulges in kleptoparasitism and takes prey from other birds. It also captures flying insects in the air. They sometimes impale prey on a thorny bush after feeding just on the head or brain. They have been reported to feed on the fruits of the neem in Kerala, even attempting to impale them on a twig.

The breeding season is in summer in the temperate ranges. The nest is a deep and loose cup made up of thorny twigs, rags and hair. This is placed in a thorny bush, trees such as Flacourtia and wild date palms (Phoenix). The usual clutch is about 3 to 6 eggs which are incubated by both sexes. The eggs hatch after about 13 to 16 days. Young chicks are often fed with pieces of small birds captured by the parents. A second brood may be raised in the same nest. They are sometimes parasitized by cuckoos such as the Common Cuckoo (Dehra Dun), Common Hawk-Cuckoo, Jacobin Cuckoo and the Asian Koel in Bangladesh.
