Western Screech Owls

A few months ago I put up two screech owl nest boxes in my yard. Each box has a 3″ diameter hole which is within the size recommended to accommodate screech owls. Within a week an owl found both nest boxes and would randomly appear sitting in the entrance to one for a couple months. It wasn’t long before breeding season began and a second owl appeared. They paired up and chose the red nest box which was in a shady protected area in a false willow tree.

Both adults began hunting foray’s to feed hungry nestlings. It appeared that the male would catch prey and give it to the female who was, early on, incubating eggs, then later, feeding the nestlings.

A few days ago I decided to take a short video inside the nest box using a tiny borescope inspection camera. I wanted to see how old and how many owlets there were. I waited until after the female left the nest box in the early evening and was able to capture this video, confirming 3 downy nestlings:

Seeing the nestlings and their size made sense given how many prey items the adults were bringing into the nest box. The prey has varied from small moths and non-native geckos to a small passerine bird, a large Western blind snake (pencil-size diameter, maybe a foot long) which escaped, and a couple kangaroo rats. Here’s the video from last night’s action:

  1. Thank you! It’s been fun to document their nesting journey. The female tends to take more baths, usually in the evening after all day tending to her nestlings in a hot nest box (day time temps are 100 degrees now) and in the early morning before retiring to the nest box for the day.
