The black-thighed falconet is one of the smallest birds of prey, typically measuring between 14–16 centimetres (5.5–6.3 in) long, with a 27–32 centimetres (11–13 in) wingspan, which is a size comparable to a typical sparrow. It is native to Brunei, Myanmar, Thailand, Malaysia, Singapore and Indonesia, and vagrant to Sri Lanka.
Region
Southeast Asia
Typical Environment
Occurs from southern Myanmar and western Thailand through Peninsular Malaysia and Singapore to the Sundaic islands of Indonesia (notably Sumatra and Borneo) and Brunei; vagrants have reached Sri Lanka. It favors forest edges, open woodland, secondary growth, riverine corridors, and human-altered landscapes such as plantations and village outskirts. Often seen near clearings or along roads where suitable perches provide hunting vantage points. It avoids dense interior rainforest but thrives in mosaic habitats with scattered tall trees.

Among the smallest raptors on Earth, it is sparrow-sized yet highly agile and bold. It often perches conspicuously on dead snags along forest edges and plantations, sallying out to snatch large insects in flight. Pairs and family groups may roost together in tree cavities, and they readily use old woodpecker holes for nesting.
