Groove-Billed Ani

Crotophaga sulcirostris

Groove-Billed Anis are resident in most of their range from either coast of the Mexican mainland, south to northern and coastal northwestern South America, with a little migration to breed in southern Sonora. In south Texas they are at home in arid lowlands and live in family groups. These very social members of the cuckoo family stay together in small colonies, sharing a single nest and the duties of rearing the young.

In February 2017, while on a science expedition to the Revillagigedo Islands, 600 miles off the Pacific coast of Mexico, we discovered one of these birds at Isla Socorro. It was alone and must have felt very out of place and isolated. My spring expedition to south Texas yielded additional meetings at Resaca de las Palmas, west of Brownsville (Texas).
