Hi Cody,
You're off to a really great start with 74 species already. You don't know how lucky you were to have been at the Beamer Hawk Watch on the day when the Black Vulture flew over, most of us have never had the pleasure of seeing one in Ontario yet, including myself. You live in a very good area for bird watching and you should see lots. I think that you should have no problem reaching your goal of 100 once the Warblers and other little birdies start coming back in to the province. Good luck!
My 2010 species count is now at 102 and my best bird so far this year is a Varied Thrush.
