Nice set of shots, the subjects themselves are pretty common but you did a good job of capturing them IMO.
What is the EXIF info on the first two shots? Both shots seem to lack sharpness a bit but it doesn't look as though the shots are OOF, it looks like lense shake got the first one, and maybe motion blur on the head of the blue jay. I'd be interested to see if maybe that's something you can tackle with different settings or not.
The Chipmunk I really like, the expression is a nice capture that kind of gives me a feeling of curiosity which I like. I might have made the shot ever so slightly wider to capture the entire tail, or cropped out the tail entirely, but otherwise it's really good work.
And bugs... I just don't like bugs. Nice shot though
