On this evening, I had the opportunity to go for a bout of night birding with a group led by Byron Butler and Tom Forwood (park naturalist). We went late in the afternoon toward the cavern entrance, and we had Canyon Wren, Green-tailed Towhee and Western Tanager. The evening started off slowly with a few Lark Sparrows and a Sage Thrasher. As darkness fall, we started to get the first poorwills as the Little Brown Myotis were filling the sky as well.
