The blue grosbeak ( Passerina caerulea , Syn. : Guiraca caerulea ), also Light blue bishop called, is an American bird art from the family of cardinals (Cardinalidae).
features
Azure bishops who reach a body length of 17 centimeters have a pronounced gender dimorphism .
The dark blue male has brown wing bands, a black face and a conical beak, the female is dark brown on top, paler on the underside and has cream colored wing bands.
Occurrence
The Azure Bishop breeds in the temperate regions of North America , but then moves south and spends most of the year in Mexico , Central and South America, and the Caribbean .
Reproduction
During the mating season, the male sings from an elevated place. With loud, trilling calls it delimits its territory 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 hatches them and feeds the young. As soon as these have fledged, the male takes on further care. The female breeds a second time. The brown-headed cowbird often tries to slip eggs under the azure bishop. The Azure Bishop then sometimes builds a second story over the nest. It has also been observed that he raises his own young and those of the brood parasite at the same time.
