Identificación

The short-tailed pygmy tyrant is truly a pygmy of a bird, with only a handful of the smallest hummingbirds measuring smaller. The average length is 6.5 cm (2.6 in) and the weight averages at 4.2 g (0.15 oz). While the bill (though slender) is disproportionately large for the size of the bird, the tail is practically non-existent. The head is gray with blackish lores and stand-out white "spectacles". The back is bright olive-green, and the bar-less wings and tail are both black. The underside is yellow-tinged white, with light olive smudges on the chest and flanks, and the inner flight feathers are edged with yellow. The sexes are similar. Although its plumage is similar to some other tyrant flycatchers, especially the slaty-headed tody-flycatcher, in the field, the bird is more often mistaken for a large beetle or insect, especially while in flight.<p>Its song is a high pitched series of up to 15 c'r'eek notes, at first hesitant, then accelerating and descending slightly. There is also a cr'e'e'e', k'e'e'e'e song that is repeated over and over. Chirp-like squeaks similar to that of a well-rosined bird squeaker and a soft, purring series of trilled notes, lower in pitch than other calls, are heard. In general, the vocalizations of the short-tailed pygmy tyrant are all unlikely to be recognized as bird vocalizations, but are rather more like the sounds made by crickets or small frogs.

Distribución y hábitat

A resident of tall humid forests, the bird is occasionally found in more open woodland, specifically around treefalls and tall trees in clearings. It ranges from sea-level to 750 m (2,460 ft). It is fairly common throughout most of its range, but is easily overlooked, in part due to its insect- or frog-like voice.
