Eastern bluebird in Huntley Meadows Park in Virginia. Life history.
If bluebirds do remain in a region for the winter, they group and seek cover in heavy thickets, orchards, or other areas in which adequate food and cover resources are available. When the babies are 28 days old, they can fly well. Western Bluebirds readily take to nest boxes. A high percentage of Eastern Bluebirds in North America today nest in birdhouses put up especially for them along "bluebird trails." Eastern bluebirds are very social birds. Studies on Western Bluebirds found that the vast majority of mated pairs stay together for life. Cardinals and other birds also do this.
“After that, they will do a courtship dance to try to find another mate.” Mute Swan Mute Swans. The Eastern Bluebird’s most common call is a soft, low-pitched tu-a-wee with a querulous tone.
However, few people get a behind-the-scenes look at what it really takes to survive and reproduce as a bluebird.

The females do almost all of the nest construction, gathering grasses, straw, pine needles, moss, other plant fibers, and fur from the ground and carrying it to the nest. Number of Broods: One to four broods per year. They are generally "socially monogamous," meaning that a single male and female form a basic social unit in breeding territory. This behavior is called mate-feeding. But many scientists have discovered that they no longer stick to just one mate. Nest Description. Today we will go past the nest box walls and into the secret life of the bluebird. And where do they keep their reproductive organs?
The females may be socially monogamous but they are capable of mating with more than one male bird. Males will get food and feed it to the female. The answer is probably maybe sometimes. Bluebirds give this song in all seasons as a way of keeping in touch with each other or to signal nestlings that adults are bringing food. Once they have found a suitable mate, the sex act is surprisingly quick. Although it is mostly "eastern" in our area, its total range extends south to Nicaragua. In long-term studies of the natural history of Western Bluebirds, scientists found that only about 6% of 117 pairs studied changed partners when both members of the pair were still alive and returned to breed.
