Song Description:

The Ferruginous Pygmy-owl's call is a long series of repeated hollow whistles which can be easily imitated by humans. Howell and Webb (1995) claim that calls may sometimes end with a series of "high, yelping twitters" while Stiles & Skutch (1989) suggest a "sharp bark or whinny" terminates some calls.

Song Measures:

Each of the short identical syllables is an upslurred whistle, rising from 1170 to 1320 Hz.  Syllables are repeated in long phrases at a rate of approximately three per second.  Davis (1972) reports that one phrase may contain from 10 to 60 syllables, although I recorded one phrase that contained only four (N = five songs from one individual in Nueva Becal).

Singing Behaviour:

Pygmy-owl calls elicit a strong mobbing response from many passerines, including many warblers and vireos. Imitation of this vocalization often attracts more small passerines than pishing does.


Ferruginous Pygmy-owls were heard very frequently in both thick forests and shrubby woodlands, often calling from within the thickest foliage.
