lazuli bunting
Passerina amoena
Taxon biology 5
Lazuli Buntings (Passerina amoena) are found over most of the United States and adjacent Canada west of the Great Plains. They breed in arid brushy areas in canyons, riparian thickets, chapparal, scrub oak, and open woodland. In summer in the western United States, they are common around thickets and streamside trees. In migration and in winter, they also occur in open grassy and weedy areas. The wintering range extends from southern Arizona and northern Mexico to southern Mexico.
Lazuli Buntings feed mainly on seeds and (especially in summer) insects (young are fed mostly insects). The nest is bult by the female in shrubs, vines, or low trees, typically around a meter above the ground. The female lays 3 to 5 (usually 4) eggs. At some nests, nestings are fed entirely by the female whereas at others the male assists. Young leave the nest around 10 to 12 days after hatching. If the female initiates a second clutch, males may take on a greater share of feeding the fledglings from the first clutch. Fall migration begins early, with many birds already moving by late July. Migrants stray east of the breeding range on the Great Plains, especially in spring.
Lazuli Buntings and Indigo Buntings (P. cyanea) are closely related species that hybridize where their breeding ranges overlap in the western Great Plains and eastern foothills of the Rocky Mountains of North America. Carling and Brumfield (2009) and Carling et al. (2010) reported on population genetic analyses to investigate the genetic architecture and dynamics underlying this interaction in the Great Plains. In addition to the range overlap in the Great Plains, since the mid-20th century, Indigo Buntings have extended their breeding range into New Mexico and Arizona, but their interactions with Lazuli Buntings here have not been as extensively studied as in the Great Plains. Lazuli and Indigo Bunting males defend territories against each other (behavior not typically seen between members of different species).

Migration 6
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: Yes. At least some populations of this species make annual migrations of over 200 km.
Many but not all individuals migrate in fall to molting areas in southern Baja California or the region bounded by southern Arizona, southwestern New Mexcio, and northern Sonora before continuing on to the winter range in western Mexico (Young 1991).
