We braved the mosquitoes on Paynes Prairie for a while, watching this family of Bluebirds. It seemed a little late for a baby to still be in the nest, but according to the Stokes Behavior book I consulted in this part of the country they can raise more than one family during the nesting season.
The two birds outside the nest, the parents we assume, flew off to catch food and came back, perching at the outside with head inside.
Karl took this beautiful family portrait.
