I live in Fort Collins, and in the past few days have seen early arriving broad-tailed hummingbirds, tree and barn swallows, yellow-rumped and orange-crowned warblers. With the ongoing snowstorm, I have been wondering about the level of mortality that these migratory birds will experience. I did a bit of searching on Google Scholar and came across an excellent article that discusses migration and weather-related deaths. The article is titled: "Weather-related mass-mortality events in migrants". It seems likely that a large number of small insectivorous birds will die during this winter storm.
