Late snow and migratory bird mortality?

[Rick]

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.

I've been wondering this as well, but more about the birds that have already started their nests here. I guess it's mostly larger birds that have laid eggs by now, like the cliff-nesting raptors, rather than the passerines.... but that's only my impression. I wonder how they get on with all this bad weather.
