Good article on snowy owls with focus on their food at http://www.theguardian.com/environment/2014/feb/24/snowy-owl-lemming-population-us-canada At the foot of the page are links to good articles on state-of-the-art tracking of migrants, and on chironomid midges, whose hatches in Magee Marsh largely fuel the Crane Creek spring warbler arrivals. I have seen a cloud of ~100+ ruddy turnstones dashing down lanes in the crowded beach parking lot there chasing these goodies. You could hear the mandibles snapping. If you're really interested in Ohio midges, check out http://animaldiversity.ummz.umich.edu/accounts/Chironomidae/ . The Ohio EPA actually has a field guide to their larvae, for the truly obsessed: http://www.epa.ohio.gov/Portals/35/documents/Midge_Larvae_Key_nov2012.pdf .
