Burrowing Owl (Athene cunicularia) Cape Coral, S. W. Florida, USA - 02/07/2018

Interesting Tidbit: A family of burrowing owls can consume 7,000 insects and 1,800 rodents in one season. Burrowing owls cannot actually dig their own burrows. Burrowing owls can fly, but they are not considered to be the most efficient fliers. ~Owl Research Center

You’re going to ask me what causes this. Short answer is I haven’t found one yet, but I did this previous post that looks into a few potential reasons.
