Fox Sparrow

Well Monday was 80 degrees or so and I had to get out! Carlos Avery still has its gates closed so I walked the south section right near the entrance to the Wildlife Science Center. The first 20 minutes I didn't see anything but after that things got a lot more interesting. I saw a number of birds: Trumpeter Swans, Hooded Mergansers, Fox Sparrows, Tree Sparrows, Eastern Bluebirds, and others I'm sure I'm forgetting. Here's a few pictures from the day.

I should probably know this one, but I'll be honest any help here would be greatly appreciated.
Thanks to all that replied.
