Blue Grosbeaks ( Guiraca caerulea )

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, distinguish this species from the indigo bunting. Length can range from 14 to 19 cm (5.5 to 7.5 in) and wingspan is from 26 to 29 cm (10 to 11 in).[3][4] Body mass is typically from 26 to 31.5 g (0.92 to 1.11 oz).[5]
