Laggar falcon juvenile in flight. Juvenile laggars are brown birds overall, very similar to juvenile saker falcons Falco cherrug. Markings on underparts vary from dark chocolaty brown to sparse brown blotches.

The laggar falcon (Falco jugger), also known as the lugger falcon or jugger (from Hindi जग्गर — jaggar, “falcon”), is a mid-sized bird of prey which occurs in the Indian subcontinent from extreme southeastern Iran, southeastern Afghanistan, Pakistan, through India, Nepal, Bhutan, Bangladesh and northwestern Myanmar.

It resembles the lanner falcon but is darker overall, and has blackish "trousers" (tibiotarsus feathers). Fledglings have an almost entirely dark underside, and first-year subadult birds still retain much dark on the belly.

This species belongs to a close-knit complex of falcons known as hierofalcons. In this group, there is ample evidence for rampant hybridization and incomplete lineage sorting which confounds analyses of DNA sequence data to a massive extent; molecular studies with small sample sizes can simply not be expected to yield reliable conclusions in the entire hierofalcon group. The radiation of the entire living diversity of hierofalcons seems to have taken place in the Eemian interglacial at the start of the Late Pleistocene, a mere 130,000-115,000 years ago; the laggar falcon represents a lineage that arrived at its present range out of eastern Africa by way of the Arabian Peninsula which during that time had a more humid climate than today.

Juvenile laggar falcon

Laggar falcons used to be the most common falcons in the region, but numbers have declined markedly in recent times and today it is probably nowhere a common species anymore. The main threats are the intensification of pesticide use in the region and use as a decoy to trap large falcons.
