There are actually three bluebirds - Western, Eastern and Mountain. The Mountain bluebird looks quite a bit different than the other two.
Both the Eastern Bluebird and Mountain Bluebirds are about 7". Approx. the same sizes.

The Eastern, Western, and Mountain bluebirds make up the Family Sialia.There is also a "bluebird" called the Fairy bluebird. They are completely unrelated to the bluebirds in the Family Sialia instead belonging to the Family Irenidae and the Genus Irena.
They give many bluebirds a place to live at the same time. The population can increase because of the amount of bluebirds that can nest in that area.a bluebird trail is a group of nesting boxes. this helps the bluebirds because then they have places to live and have babies.
No, bluebirds are not swallows.

No. These are different species.
House sparrows and wrens often compete with bluebirds for the same nesting house. Often time sparrows will break bluebird eggs or make another nest over the current bluebird nest.
Yep! Bluebirds are birds and birds are animals.
