Breeding Status of Rose-throated Becards Along the Santa Cruz River, Arizona
Rose-throated Becards (Pachyramphus aglaiae) are rare in the United States. On occasion, small groups of nests develop just north of the Arizona/Mexico border. Nests in a specific area often proliferate over a period of years and then just as suddenly disappear. One such cluster of nests was found and documented along the Santa Cruz River in Santa Cruz County, Arizona in the late 1940s. More than 70 years later, Rose-throated Becards are again nesting here and over the past 5 years at least 19 nests have been confirmed, with over 28 juveniles detected. This is now the only active breeding population of this species in the United States.
