Turquoise-browed motmot (Eumomota superciliosa) is a coraciiform bird of the family Momotidae native to Central America, and as the "Guardabarranco", it is the unofficial national bird of Nicaragua.[2]

Description

Turquoise-browed motmot are about 13.3 inches in length, including the long, racqueted tail. The wings are short and rounded, with a span of about 5 inches. Above they are green with a rufous across the back; when ate rest the folded wings are banded in green, turqoise, and dark blue. The underparts are olive-green with a rufous belly. A black mask covers the eyes, in which the top edge of the mask is turquoise-blue, hence the name. The bill is rather large and has a slight downward curve with serrated edges.

Turquoise-browed motmots still-hunt, i.e. they sit on a perch for a period of time until a prey animal comes into sight, then they swoop down to make a rapid snatch. Prey consists of insects and other invertebrates, small reptiles and rodents. Fruits are also part of the diet.

Range and habitat

Turquoise-browed motmots are found in southern Mexico, south to Costa Rica. It inhabits dry arid to semi-arid woodlands, scrub forest, and open pasture lands. They also inhabit tropical forested areas, but in those portions which have been largely cleared or in secondary growth.

Breeding

Both male and female are monogamous, and some pairs will remain with each other for several years. They nest in difficult-to-find holes dug into river banks or the forest floor in March, with the entrance pipe some distance as well as curved before it ends at the nest, with both birds excavating until the tunnel and chamber is up to five feet long. Four, and sometimes five, white eggs are laid from April to May, with an incubation period of 17 days. At 28 days the young birds fledge. Turquoise-browed motmots have also been observed laying a second clutch of eggs after the first brood has left the nest.
