Blue # Grosbeak (lat.Passerina caerulea)

North American songbird of the cardinal family (Cardinalidae). Some authors attach the species to the family of buntings (Emberizidae).

The dark blue male has brown stripes on the wings, a black face and a conical beak, the female has a dark brown upper side, and the underside is paler, cream-colored stripes on the wings.

The blue guiraca is common in the temperate regions of North America, migrates south and spends most of the year in Mexico, Central and South America, and the Caribbean.

During the current, the male sings from a high place. With a loud trill, he marks his site and tries to attract a female. The female alone builds a nest in a bush or low tree and lays 3-4 eggs. The female incubates them and feeds the chicks. Once they become self-reliant and, the male takes on further care. The female then nests a second time. The brown-headed bovine corpse often tries to toss an egg into a bird's nest. The blue guiraca then sometimes builds a second floor above the nest. It has already been observed that the bird simultaneously feeds its own chicks and the chicks of the nest parasite.
