"Someone's been sleeping in my bed," said the little owl...

Earlier this week a reader of my Weekly Nature Watch column (Enterprise newspapers) called to tell me they had a screech owl sitting on a branch in their yard. They had previously had screech owls in a nesting box they had built but the day before they called me a squirrel had moved into the box. It was rainy, windy and cold the day I went over and sure enough, there was the little screech owl sitting on the branch, watching the box.....Every now and then the squirrel peeked out of the box but mostly it stayed inside and let the owl stare and stare and get wet and cold.....Screech owls are pretty common on the Cape and they are fairly easy to lure to nest boxes. Owl nest boxes have a 3" hole which unfortunately is plenty big for squirrels, too. You can see that this box has even had the hole edges chewed on, most likely by squirrels, which enlarges the hole. It is not uncommon for screech owls and squirrels to go back and forth winning the box back and then losing it again. Home owners that prefer the owls are encouraged to clean the squirrel nest materials out of the box daily so the owl can return. The squirrels may still win, however.
These homeowners were adding several other nest boxes this week so it will be interesting to see what happens next. Screech owls are using boxes or holes in trees to roost right now. They don't nest until February or March. You may be hearing great horned owls right now because they are getting ready to nest and all that hooting is helping them find a mate. Screech owls don't hoot, by the way. They either let loose with a blood curdling screech or make a sound that is sort of like the whinnying of a horse.

  1. That's neat! I never knew that about screech owls and squirrels...we don't have too many out here in the desert.
