Both parents are very busy trying to keep the five babies fed. During the nesting season, the Bluebird's main diet consists mostly of insects and other invertebrates such as crickets, spiders, beetles and may also include grasshoppers and katydids. Other food items include earthworms, spiders, millipedes, centipedes, sow bugs, and snails. During fall and winter they switch over to berries and fruit when necessary. These 2 Bluebirds seem to find a lot of spiders and worms as you can see in the pictures below. They have had to be careful about flying down in my yard to get any bugs because the mockingbird that has a nest in my neighbor's yard dives down and attacks them on the ground.
