Summary ⁶

The blue grosbeak (Passerina caerulea, formerly Guiraca caerulea), is a medium-sized seed-eating bird in the same family as the northern cardinal, "tropical" or New World buntings, and "cardinal-grosbeaks" or New World grosbeaks. The male blue grosbeak is almost entirely deep blue. The female is mostly brown. Both sexes are distinguished by their large, deep bill and double wing bars. These features, as well as the grosbeak's relatively larger size (ranging from 5.5 to 7.5 inches in length), distinguish this species from the indigo bunting. The COSA is within the Blue Grosbeak's breeding range and so can be spotted there from April to August
