Burrowing Owls and Winter

As you know if you’ve been following my blog, I’ve read a bunch of books on Burrowing owls and didn’t find the answer of how do burrowing owls survive winter. Once I had gone through my pile of books I did a Google search which didn’t really help either. Finally, I went to the library research databases. I had a feeling all along that it would yield my answer and I was right.

Burrowing owls have several strategies for surviving the winter.

One: Pick up and move south to Mexico and find a roost site (still a burrow). If appropriate burrow sites are close together the owls will live close together. Though food availability is another factor in how many owls can live near each other.

Two: Stay put as long as the snow doesn’t get too deep or the temps too low. This is usually only for populations in the southwestern states.

Three: Most suprisingly there was at least a little evidence that an occasional owl will move north. It is speculated that this is so that they can claim better roosting/burrow sites.

So there you have it, they migrate except when they don’t depending on the weather. BUT they always roost in burrows which I discovered was another of my un-asked questions. — Jenny
