The pygmy falcon is the smallest bird of prey on the African continent, and among the smallest raptors on earth; only the Asian falconets (of the genus Microhierax) are smaller, weighing roughly 30-40 grams less and measuring about 5 cm shorter from head-to-tail.
The largest falcon is the gyrfalcon at up to 65 cm (26 in) in length. The smallest falcon species is the pygmy falcon, which measures just 20 cm (7.9 in).
