This species is crepuscular, but often hunts by day. It hunts a variety of birds, lizards, mammals, and insects. The flight is low to the ground and rapid with long swoops.

It can be readily located by the small birds that mob it while it is perched in a tree (up to 40 birds of 11 species have been recorded mobbing one owl).

The ferruginous pygmy owl is small, typically 15 cm (5.9 in), and stocky with disproportionately large talons. The crown has elongated white/buff spots or streaks, the wing coverts have white spots, and the underparts are heavily streaked white. There are prominent white supercilia above the facial disc.
