Registro del colibrí barba negra (Archilochus alexandri) en el estado de Querétaro, México

We report the first records of the Black-chinned hummingbird ( Archilochus alexandri ) for the State of Queretaro, Mexico. These records correspond to three sites, The Parque Nacional El Cimatario, The Parque Nacional Cerro de las Campanas and a remnant of vegetation inside the city; where we observed the species during its migratory season, from 2014 and until 2017.  The Black-chinned Hummingbird visited mistletoe flowers ( Psittacanthus calyculatus ), morning glory flowers ( Ipomoea murucoides ) and red justicia flowers ( Justicia candicans ). This information confirms the presence of the Black-chinned Hummingbird in the State of Queretaro and supports its inclusion in the list of avifauna of Queretaro.
