Primer registro del colibrí barba negra (Archilochus alexandri) en Isla Socorro, Archipiélago de Revillagigedo, México

A groundbreaking discovery has been made on Socorro Island, part of Mexico's Revillagigedo Archipelago: the first recorded presence of the Black-chinned Hummingbird (Archilochus alexandri). This finding significantly enriches the island's biodiversity and expands the known distribution range of this species. Researchers identified three hummingbirds during a November 2017 expedition, distinguishing them from smaller migratory species by their body structure and long beaks. One individual was observed feeding on amole flower nectar (Ipomoea triloba) in mixed scrub vegetation, confirming its presence. This record marks the first hummingbird sighting in the archipelago and the first for the Black-chinned Hummingbird on Socorro Island.
