For an interesting photograph of a Boreal Owl in a nest box surrounded by captured prey items, go to http://www.aibs.org/bioscience/current_issue.html The address takes you to the current issue of BioScience magazine.
The bird apparently was caching food. There is an accompanying article entitled "The Puzzles of Population Cycles and Outbreaks of Small Mammals Solved?" that can be downloaded as a pdf file. It might be interesting reading in this, the winter of owls brought to us by prey shortages. Thanks to friend Mike Mulligan of Calgary for providing the information. Jim Williams Wayzata, Minnesota
