Sumichrast's Wren

Overview

Sumichrast's wren, also known as the slender-billed wren, is a species of bird in the family Troglodytidae. It is endemic to Mexico and is currently assessed as Near Threatened by the IUCN due to habitat loss and a declining population.

Identification

• Adults measure 15 to 16.5 cm in length and possess uniform deep brown crowns, napes, and backs, with sooty brown rumps.
• The chin and throat are buff, deepening into the breast, flanks, and belly, which features faint dark bars on the breast and tiny white dots on the belly.
• Males produce a varied descending series of loud, rich whistles, while females sing a simple phrase consisting of a single repeated syllable.

Habitat

This species inhabits the understory of humid evergreen and semi-deciduous forests, as well as shady coffee plantations, but is restricted to scattered sites with extensive limestone outcroppings. Its range covers a small area of Mexico from central Veracruz into northern Oaxaca, at elevations between 75 and 1,000 m.

Diet

The diet consists primarily of arthropods and other invertebrates such as snails and worms, with small fruit making up a minor component. Foraging behaviour involves hopping and short flights on and very near the ground, probing into crevices for prey and occasionally snatching flying insects.

Did you know?

Although both sexes contribute materials to the cup-shaped nest, only the female is responsible for building it. The male compensates by bringing food to the female during incubation, while both partners provision the nestlings.
