Being part of the thrush family (Turdidae) the Bluebird is divided in three species: the Eastern Bluebird – Sialia sialis, Western Bluebird – Sialia mexicana and Mountain Bluebird – Sialia currucoides.
Weight 2 to 5 ounces
Height 15 cm (5.9 in) to 18 cm (7.1 in).
Color The male is always bigger and brighter colored then the female regardless to which of the tree species we mentioned earlier he is part of. The predominant color in males is blue and also the females have blue on their bodies. Their blue and red color makes them very eye catching.
The mountain bluebird is a migratory species and so they migrate during the winter and can be fund from Alaska to Mexico depending on the season or the southern birds just stay there all year round. The preferred altitude of these birds is around 5000 feet. Although these birds were once in danger as cause of the lack of natural cavity’s that are used not only by them but also by many other different species of birds they are now doing quite well since many people contributed to their welfare by building bird houses and placing them in the wild.
As for the other two species of bluebirds their diet and nesting behaviors are identical they all eat insects that are close to the ground which they usually catch in flight, small berries, worms and peanuts; and they nest into tree cavities or human made bird houses.
The female lays around 3 – 5 eggs which hatch after a 14 day period of incubation, the chicks will need another 21 days of care before they can leave the nest on their own.
