Some Birds

I made a brief stop at the Belle Isle Nature Zoo today.  I'd never been there before but they were open and I needed to use the facilities there.

 Since I was there, I decided to take a walk around.  I discovered that they had a nice little birdwatching spot, so I decided to get some pictures.  I'm not sure what kind of bird this is.

 But I thought he looked pretty cool.

 The ever elusive Blue Jay.

 I think this is a sparrow.

But I'm not sure.
