I have attracted bluebirds using mealworms and birdbaths, but I have not been successful with them nesting in my bluebird box until this year.
In the past, bluebirds have attempted to build a nest, only to have sparrows evict them. This year a pair of bluebirds laid eggs and produced four nestlings.
Two weeks ago, the baby bluebirds left their nest or fledged. When I walked outside, several adult bluebirds dive bombed me, and I spotted four fledglings hopping on my lawn.
Fledgling survival depends on the parents hearing their call and finding them. The parents will continue to feed and care for them for three to four weeks as they learn independence.
Unfortunately not all fledglings survive. The day after I saw the baby bluebirds, I found fledgling feathers on the lawn, and I suspected that a predator attacked at least one of them.
Some of their predators include snakes, fire ants, opossum, mice, rats, owls, and raccoons. In addition, humans also threaten their survival through pesticide use and removal of their habitat through development.
Some sources say about 50 percent of fledglings will not survive, but I suspect that the number is greater.
