Hungry fella? She has a fish (or something) in her mouth here:
You can tell it's a female in this picture (although very distant and out-of-focus) because of the rust-colored markings (red chest band) on her breast.

I read up on All About Birds and learned that Belted Kingfishers are one of the few species where the female is more brightly-colored than the male. They hunt by watching the water from their perch or hovering above, and then dive head-first into the water. They then fly to a perch and smash their prey then eat it (which is what can be seen in the middle picture).

It seems all of the birds were in the middle of lunch! Here's a Hairy Woodpecker with a nut or bug in its mouth.
It can be difficult to tell the apart Downy Woodpeckers and Hairy Woodpeckers. I generally rely on size for these. It's tough because this picture was taken a few weeks ago so I can't remember the exact size, but I do think it was on the larger side.Here's a Northern Mockingbird we saw during our hike at the Flatirons. That was the only species I saw during the hike actually. I followed a couple of different mockingbirds hopping around on the rocks and low branches of the trees.

It was a great vacation, and it's also great to be home and catch up on stuff around the house and blogging of course!

@Patrick- thanks for the tip! I'll definitely look into it. They're very close, so I'll see if I can pull up some of the other shots I had of it and compare.
I also see on your blog that your friends were mentioned in a Patriot Ledger interview about the Ivory Gull- very cool!
