Taxonomía

In the first half of the twentieth century the barred puffbird was treated by some authors as belonging to genus Ecchaunornis, but since then was returned to genus Nystalus. It is monotypic. A proposed subspecies, "N. r. fulvidus" is probably a color morph.

Distribución y hábitat

The barred puffbird is resident from central Panama into northern Colombia and through western Colombia into western Ecuador. It inhabits the lower levels of several semi-open landscapes including the borders of humid and wet forest, streamside vegetation, clearings with scattered trees, and the edges of forest trails. In Ecuador it has regularly been recorded perched on wires in agricultural areas. In elevation it is usually found up to 900 m (3,000 ft) but has been recorded locally in the Mindo, Ecuador region as high as 1,675 m (5,500 ft) and once at 1,550 m (5,100 ft) in Colombia.

Comportamiento

The barred puffbird's foraging behavior has not been documented; other puffbirds typically hunt by sallying from a perch. Its diet includes large insects of several orders and small lizards.<p>The only described nest of a barred puffbird was a cup of dead leaves. It was in a spherical chamber at the end of a narrow tunnel excavated in a clay bank and partially shaded by vegetation. It contained two well-grown nestlings.<p>The barred puffbird's song is "a long, slow, ventriloquial and very human-like wolf-whistle, 'phweeeeeet-weeeeeeuuuu'". Near the nest it made low-pitched "werr" and "werr werr woo" calls.
