Since our owl nest box overflowed with litter in 2011, we stared cleaning it out every year beginning for the babies of 2012. It became a tradition to empty it out every year at Thanksgiving, after the young owls had moved on, in preparation for use in the spring. This last year on 11/24/16, we got a surprise. When we started lowering the box, an owl flew out! We thought it was roosting in there because of the cooler weather. But when the box tilted we heard two cracks against the side. Shocked to see eggs inside, we put it right back up…. and waited to see what happened. The eggs were due to hatch at Christmas time.
The mating behavior continued through early December and the female owl stayed in the nest box every night. Since they normally lay 3 to 5 eggs, we hoped that even if the two were damaged, it would be OK. The female was nervous after that… leaving the box and making noises in the palm tree when we weed whipped below. The weather since then has been rainy and cold… frosty even. After receiving 6 inches of rain in the last week or so, I was finally able to sit out and listen last night. It’s official! There are definitely baby owls in there. The female flew out to hunt with her mate, leaving the young alone for awhile. I could hear at least 2 or 3 baby owls screeching inside.
As to why they are breeding during the winter, I have a theory. Our last brood of young owls left last June. We also have a neighbor with owl boxes that had several babies during that time, so there were lots of owls looking for new territory. In late July, there was another couple of owls that were trying take over the nest box and our resident pair were very upset! There was fighting like I’ve never seen before. Screeching (even during the day) and going after each other like crazy! I think that this may be a new couple, and they wanted to breed and make the box their own as soon as possible. Be sure to stay tuned…
