Some bluebirds won’t be returning to this area until later in April. As we have seen in the past, the early birds such as the red-wings, robins and bluebirds often get their pick of what they ...
Adult female in Livermore, California. The western bluebird is a small stocky bird with a length of 15 to 18 cm (5.9 to 7.1 in). The adult male is bright blue on top and on the throat with an orange breast and sides, a brownish patch on back, and a gray belly and undertail coverts.
In many species, parents continue to care for their fledged young, either by leading them to food sources, or feeding them. Birds are vulnerable after they have left the nest, but before they can fly, though once fledged their chances of survival increase dramatically. [5] A pigeon fledgling on a tiled floor
Bluebirds have two or three nestings per year so do not give up trying to attract them. Keep monitoring your bluebird nest boxes and make sure that they aren’t occupied by house sparrows.
This species is a small swallow at 18–25 centimetres (7.1–9.8 in). The adult birds have a highly lustrous dark metallic steel-blue appearance with long tail streamers, which are particularly noticeable in males. White feathers are visible on the rump and flanks when the birds are preening and especially during courtship.
The young will usually take about 21 days before they leave the nest, and it can take up to two months to raise fledglings to a stage of development at which they are able to fend and provide for themselves.

After the juveniles fledge, the family travels and forages together until early fall, when the young birds disperse to avoid competition for food during the winter. Sexual maturity is reached after one year of age. The oldest known wild, banded Blue Jay was at least 26 years, 11 months old when it was found dead after being caught in fishing gear.
They generally fledge about 18 to 22 days after hatching. The tree swallow is sometimes considered a model organism, due to the large amount of research done on it. An aerial insectivore, the tree swallow forages both alone and in groups, eating mostly insects, in addition to mollusks, spiders, and fruit. The nestlings, like the adult ...
