Watch birds and hummingbirds at the visitor center

While we were at the visitor center we saw a ton of Rufous Hummingbirds and Black-Chinned Hummingbirds. There are two feeders right by the front door and they were everywhere.

We went back after the visitor center was closed and were able to photograph them.

Check out the wipe board in the visitor center to see which birds have been seen at the feeder.
