In my experience, April is the best birding month of the year followed by May. In April 2009, I saw or heard 148 species of bird. In April 2010, I encountered 153 species. After going to the Natural Resources Complex to try to pick up Acadian Flycatcher and getting Wood Thrush instead, I close April 2011 out with 162 species for the month. My best month ever. At every opportunity, I went out and on April 20th started five weeks of half days at work so I was able to bird somewhere every day since the 20th. I don’t expect May to be as good but the pace enabled me to reach 200 birds for the year, none exotic except those that have been corroborated by someone else, on April 29th.
