Black-thighed Falconet 黑腿小隼
"The smallest of the falcon family is the sparrow-sized Black-thighed Falconet found in Indonesia and Malaya, which weights between 1 and 1 oz (28-56g)."
They "live in open woodland or at the edges of forests where they mainly prey on flying insects, especially butterflies, moths and dragonflies. They employ a 'still hunting' technique - they perch on branches, waiting to dart out, grab their prey and return to the same branch to feed".
quote from "Birds of Prey, Majestic Masters of the Skies" by Paul D. Frost.
