*Their diet is mainly insects, most of which are yard and garden pests. In the spring they love the cutworms
that ruin crops and garden plants. Later in the summer through fall they dine on
huge quantities of grasshoppers and wild berries. It is said that their
courtship is beautiful and amazing, but it is a rare sight to behold.
The Bluebird is very territorial, the male protecting his food supplies from
other male Bluebirds trespassing. The nesting site must have sufficient food for
them to raise their young and exist themselves for them to be tempted to set up
housekeeping.
Only the female builds the nest in the chosen shelter, while the male
accompanies her solely by singing his encouragement while she works.

Nest building starts in mid-May in Michigan and 3 to 5 clear blue eggs are
laid in the clutch. The baby birds grow alarmingly fast, ready to leave the next
in 15 to 20 days after hatching. By that time they are strong enough to fly
fifty to one hundred feet their first attempt at flight to the nearest perch.
By early September most Bluebirds have finished up their family
responsibilities for the season. A fortunate pair will have raised two or even
three broods by that time. During the fall, families of Bluebirds roam leisurely
through the countryside on a quest for insects and berries in great abundance.
Over these travels, different families join together in a loose flock, as
they get ready for migrating. The date of their heading south is timed more by
the weather and food supply than by the calendar. They migrate in search for
food and congregate in more southern parts of their regions. *www.wild-bird-watching.com/bluebird-history.html |
