Here are a couple of shots of a Carolina Chickadee gathering some nesting materials. It looks too cute with a beak full of fluff.
Here is a picture of a female Eastern Bluebird, also with some nesting material in her beak, this time a feather.
Here is a sequence of three photographs of an Orange-crowned Warbler landing next to a spider’s home, digging into it, and a successful hunt with a spider in its beak. Unfortunately, the last photo is a bit softer than I would like and the spider is not in good focus. It was still an awesome sequence of photos.
When I first saw this picture, I thought this Tufted Titmouse was eating a mosquito. I think it is a bit too large for a mosquito, but I am not for certain.
