What do bluebirds eat? To find out, we placed cameras at 40 bluebird nest boxes in Delaware to record the birds bringing prey back to their nestlings. The prey were identified from the video to determine which arthropod groups are most important in the bluebirds’ diet.
Caterpillars were identified as the dominant prey group, followed by orthopterans and spiders. Improving our understanding of bluebird diet is vital for conservation efforts.
This research was conducted by Ashley Kennedy in Doug Tallamy’s Lab at the University of Delaware. The video was produced with Justin Bredlau at Virginia Commonwealth University and narrated by Jessica Bray. Visit www.whatdobirdseat.com to learn more about this project.
