Blue Grosbeak

Blue Grosbeaks breed from the United States south to Costa Rica. They nest in shrubs along forest edges or roadsides (Lowther and Ingold 2011). Erika and I flushed this one from a roadside near the Ensenada Lodge in Costa Rica on 8 July 2017. Blue Grosbeaks eat arthropods and, to a lesser degree, seeds of weeds and grains. They are parasitized by Brown-headed Cowbirds in the United States and by Bronzed Cowbirds in Central America.
