Laggar Falcon

Adults are dark overall and have blackish feathers on the tibia. It used to be one of the most common falcons in the region, but numbers have declined so that it is probably nowhere common now (Wikipedia, general species account).

The cached account is short: it notes only that the group of hierofalcons it belongs to has evidence of rampant hybridisation and incomplete lineage sorting, and it gives no measurements, diet or breeding information (Wikipedia, general species account).
