Collared Antshrikes

The South American Collared Antshrikes (Sakesphorus bernardi) – also known as White-naped Antshrikes – occur naturally in western Ecuador and north-western Peru, west of the Andes and the Marañón valley. 

Their range stretches from Manabí south to Ancash, and also into the river Marañon basin, in Cajamarca and Amazonas, in northern Peru. 

They inhabit tropical deciduous forests, desert and moist scrublands, and mangroves.   

They are usually seen in pairs but may join mixed-species flocks – especially outside the breeding season.

Diet / Feeding:

Their diet mostly consists of insects, such as grasshoppers and crickets, beetles and caterpillars, as well as spiders; as well as feeding on various fruits. They may also prey on the young and eggs of smaller birds.    

Breeding / Nesting 

Most breeding occurs between February and May. Pairs are monogamous and raise the young together.  The eggs are laid in an unlined deep cup nests made out of dead grasses and plant stems loosely woven together. Nests are suspended from bifurcating twigs up to 6 feet above the ground.

The average clutch consists of 2-3 creamy white eggs with dark brown markings.  The female incubates the eggs for 14-17 days until the young hatch. The chicks fledge 11-12 days later.
