As some may know I'm doing my master's at the University of Waterloo, studying 'reverse migration' and the effects of weather during the spring. I've spent the last two springs on the island, both 2009 and 2010, staying from April 25-May 20. What started out as a fun idea, turned eventually into my undergrad topic, and now has morphed into my master's thesis. Basically what I've done the past 2 springs is ID what species are and how many are 'reverse migrating' aka flying south in a 'reorientation flight' in the first few hours of light.
I've seen some pretty cool things, and the numbers don't lie. Over 52 days of coverage I've tallied the following species and numbers. See anything interesting???? Based on my calculations, it takes about 1,100-1,500 birds to get something 'good'....though it depends on what you think is good. That might seem like alot, but it averages out to a good bird per day.
|Great Crested Flycatcher||4|
|Cape May Warbler||14|
|Black-throated Blue Warbler||33|
|Black-throated Green Warbler||55|
|Small Bird Sp.||668|
