bluebird

The genus Sialia was introduced by the English naturalist William Swainson in 1827 with the eastern bluebird (Sialia sialis) as the type species.{{ cite journal | last=Swainson | first=William | author-link=William Swainson | year=1827 | title=A synopsis of the birds discovered in Mexico by W.

Bluebirds are territorial and prefer open grassland with scattered trees. This is similar to the behavior of many species of woodpeckers. Bluebirds can typically produce between two and four broods during the spring and summer (March through August in the Northeastern United States). Males identify potential nest sites and try to attract prospective female mates to those nesting sites with special behaviors that include singing and flapping wings, and then placing some material in a nesting box or cavity. If the female accepts the male and the nesting site, she alone builds the nest and incubates the eggs.

Predators of young bluebirds in the nests can include snakes, cats, and raccoons. Bird species competing with bluebirds for nesting locations include the common starling, American crow, and house sparrow, which take over the nesting sites of bluebirds, killing young, smashing eggs, and probably killing adult bluebirds.{{cite journal|url=http://sora.unm.edu/sites/default/files/journals/jfo/v055n03/p0378-p0380.pdf |title=House Sparrows Kill Eastern Bluebirds|jstor=4512922|author=Gowaty, Patricia Adair |journal=Journal of Field Ornithology|volume =55|issue=3|year=1984|pages=378–380}}

Bluebirds are attracted to platform bird feeders, filled with grubs of the darkling beetle, sold by many online bird product wholesalers as mealworms. Bluebirds will also eat raisins soaked in water. In addition, in winter bluebirds use backyard heated birdbaths.

By the 1970s, bluebird numbers had declined by estimates ranging to 70% due to unsuccessful competition with house sparrows and starlings, both introduced species, for nesting cavities, coupled with a decline in habitat. In late 2005, Cornell University's Laboratory of Ornithology reported bluebird sightings across the southern U.S. as part of its yearly Backyard Bird Count, a strong indication of the bluebird's return to the region. This upsurge can be attributed largely to a movement of volunteers establishing and maintaining bluebird trails.

Bluebirds' consumption of insects make them popular with gardeners.{{cite web|url=http://theselfsufficientgardener.com/episode-109-bluebirds |title=The Self-Sufficient Gardener Episode 109 Bluebirds|publisher=Theselfsufficientgardener.com |date=2011-07-20 |access-date=2012-06-16}}

In traditional Iroquois cosmology, the call of the bluebird is believed to ward off the icy power of Sawiskera, also referred to as Flint, the spirit of the winter. Its call caused Sawiskera to flee in fear and the ice to recede.Canadian Climate of Mind: Passages from Fur to Energy and Beyond By Timothy B. Leduc p.192-195

"Bluebird of Happiness" is a song composed in 1934 by Sandor Harmati, with words by Edward Heyman and additional lyrics by Harry Parr-Davies.

"(There'll Be Bluebirds Over) The White Cliffs of Dover" was composed in 1941 by Walter Kent to lyrics by Nat Burton looking forward to a time when World War II would be over. Burton was unaware that the bluebird was not indigenous to England. Vera Lynn popularised the song with her performances to the troops.

"Bluebird" is a song written by Stephen Stills and recorded by the rock band Buffalo Springfield in 1967. It contains the lyrics "There she sits aloft at perch. Strangest color blue."
