Just Published in Avian Conservation and Ecology: Nest Box Use During the Non-breeding Season

Caitlin just published an excellent paper detailing nest box use in the non-breeding season in Idaho.

This publication is an important contribution because it discusses patterns in nest box use during a period that has received little attention. Additionally, because nest box programs are engineered to supplement natural cavities to saturate an area with nesting habitat geared to benefit species, a full understanding of its impacts throughout the yearly cycle is important. This paper not only reports how nest boxes are used in the non-breeding season, but illustrates some possible negative impacts as well. Such impacts are primarily associated with the variable thermodynamic nature of nest boxes relative to natural cavities, resulting in deaths at temperature extremes.

The paper also details some inter and intraspecific interactions in nest boxes, and patterns of use in other cavity roosting species such as the Northern Flicker and European Starling. With this discussion comes supplementary video of some such encounters, and excellent inclusion to add further context.

A Sun Soaking Western Screech Owl

Roosting Western Screech Owl- Megascops kennicottii

With the help of friends, I was finally shown a needle in a haystack. I’ve searched long and hard for the cavity roosting Megascops kennicottii. I have repeatedly checked known roost sights with no success. After my experience the past summer with the Western Screech Owl, I became even more obsessed with finding the bird in daylight. Sometimes it’s about knowing the right people and getting lucky.

It is important to remain respectful when finding a treasure such as a roosting owl. The stress the bird undergoes if it is flushed can be detrimental, especially in the winter months. If you are ever so lucky to find a roosting owl, glimpse the bird and move along. Do not overstep your bounds. After all, it would be worthwhile to ensure that the bird is comfortable with the roost sight, feeling safe and sound to return time and time again. It is then that you will be sure to have plenty of opportunities to watch the daytime dozings of the darkness dwellers.
