Se han registrado más de 150 especies de aves para el Archipiélago de Revillagigedo, pero hasta este trabajo no existe registro de una especie de colibrí. En noviembre del 2017, durante una expedición de monitoreo estacional de aves terrestres en Isla Socorro, observamos tres individuos de colibrí. Distinguimos a los individuos del género Archilochus de colibríes pequeños migratorios, principalmente por su estructura corporal pequeña al vuelo y su largo pico. Además, presentaron el morfo semejante al de la hembra adulta o un juvenil del colibrí barba negra (Archilochus alexandri), que inverna en el continente al oeste de México. Observamos a uno de los individuos alimentándose del néctar de las flores de amole (Ipomoea triloba) dentro de la vegetación de tipo matorral mixto de la isla. Este es el primer registro de un colibrí en el Archipiélago de Revillagigedo, y primer registro del colibrí barba negra en Isla Socorro, aumentando la riqueza biológica de la isla, así como la distribución del colibrí barba negra.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract. More than 150 avian species have been recorded for the Revillagigedo Archipelago, but until this study there has been no record of a hummingbird species. In November 2017, during an expedition for seasonal monitoring of terrestrial birds on Isla Socorro, we observed three hummingbirds. We distinguished the individuals as belonging to the Archilochus genus of small migratory hummingbirds, mainly due to the small body structure in flight and long beak. They also had morph similar to that of the adult female or juvenile of the Black-chinned Hummingbird (Archilochus alexandri) that winters in continental western Mexico. We observed one individual feeding on the nectar of amole (Ipomoea triloba) flowers within the mixed scrub vegetation of the island. This is the first record of a hummingbird species in the Revillagigedo Archipelago, and first record of the Black-chinned Hummingbird on Isla Socorro, increasing the biological richness of the island, as well as the distribution of the Black-chinned Hummingbird.]]></p></abstract>
