CObirders,
I just found a cooperative tail wagging Palm Warbler along Soda Creek at the culvert where Cove Rd passes over the creek. This is off Swan Mtn Rd between Dillon and Keystone. (39.596093,-106.012087)
It was working the rabbitbrush and willows next to the creek. There are lots of Yellow and Yellow-rumped Warblers in the same area. Good luck if you find yourself in the area for non-chasing purposes.
