Did our second evening bat tour at the local Yolo Basin Wetlands last night. It was very nice. They start off with a lecture and bat introduction at the Visitor Center and then a convoy heading out to the wetlands and drove way way into the back (the side near Sacramento) to just next to the causeway. Then we waited until sunset and out came the bats. Thousands and thousands of them. It was cool. Here are some videos and pics. And also some responses to my Tweets about it.
