Laggar Falcon

Overview

The laggar falcon (Falco jugger) is a mid-sized bird of prey occurring in the Indian subcontinent from southeastern Iran, southeastern Afghanistan, Pakistan, through India, Nepal, Bhutan, Bangladesh and northwestern Myanmar. It used to be one of the most common falcons in the region, but numbers have declined so that is probably nowhere a common species anymore. The main threats are the intensification of pesticide use and use as a decoy to trap large falcons.
Fledglings have an almost entirely dark underside, and first-year subadult birds still retain much dark on the belly.
