The results are consistent with a model of neutral dispersal within a genetically open population. The male Indigo Bunting is a beautiful indigo blue that is hard to miss as it sings throughout most of the eastern United States. The results are inconsistent with predictions of social and avoidance-of-inbreeding hypotheses that are based on the local natal demographic environment. Indigo buntings (Passerina cyanea) breed throughout eastern North America from the Great Plains eastward, south of the coniferous forest region. Februon this page nest location Nest Appearance phenology nest Indigo bunting eggs fledgling and parental care common problem The blue bunting is one of the most popular songbirds in North America. Watch out for indigo buntings hunting in low vegetation. Look out for fledglings in the nest in spring. The nest is most likely to be on the edge of the woodland. Its range is from southern Canada to northern Florida during the. They also like forests where plants and shrubs are starting to grow. The indigo bunting, Passerina cyanea, is a small seed-eating bird. Evidently most buntings settle and breed more than 2 km from their natal site. Indigo buntings like brushy forest edges or open deciduous woodland. Locally born birds comprised 1.6% and 13.0% of the breeding population in areas of 10 and 4 km 2. They may have a touch of blue on the wings. The proportion of nestlings recaptured in a later year on their natal area was 1.65% of 1,212 nestlings at the George Reserve and 8.78% of 1,332 nestlings at Niles. Adult female indigo buntings are brown on the upperparts and lighter brown on the underparts. A population inbreeding coefficient ΔF of 0.01 was estimated from known genealogies and matings. Some birds just take your breath away The Indigo Bunting ( Passerina cyanea ) is a bird that definitely takes my breath away. The nest is often low in a shrub and hard to detect. Females have a darker chest and throat compared with bluebird. Indigo Buntings construct a loose cup of grasses, leaves and animal fur held together with spider silk. The local distribution of dispersal distances approximated a neutral model with a decreasing probability of settling with distance from the natal site. Indigo bunting mature males are totally blue, unlike bluebirds which have an orange chest. About five inches long, the indigo bunting is a finch with a fondness for brush and weeds, where it can be seen feeding on seeds and insects. The Blue grosbeak female features much bolder patterning on her darker wings and has a stockier form. The Indigo bunting female is almost totally brown, with a lighter-brown chest and slightly darker wings. The females are a browner, more cinnamon color. Variation in distance within the natal area appeared to be independent of local population density, social competition, active kin recognition, and avoidance of incest, but was affected by date of birth. Female Blue Grosbeak vs female Indigo Bunting. Dispersal distances were independent of whether parents or siblings of either sex returned in the same year. The breeding site was not limited by prior occupation of sites by breeding adults closer to the natal territory. The distances and number of territories between natal and breeding sites were similar between the sexes.

The distinct molt limit between plain brown primary coverts and blue-edged greater coverts is indicative of a second-year male Indigo Bunting. It is also a popular cage bird in Europe and Mexico. Indigo Bunting is occasionally killed for sport and food. Breeding males have rusty wingbars that Indigo Buntings do not have. Brooding females, eggs and young are vulnerable to predation from raccoons, opossums, red foxes, feral cats and blue jays.
