Dave, Thanks for the post. I walked my dog in a couple of spots this morning, including Grandview. The Bushtits, or some of them, were in the same place you found them at ~11am today. As active as they are, and as much as my dog pulls at the leash, I was only able to count 4 visible at once, but had the sense there were at least twice that many in those spruce trees. I found no sign of the thrasher across the street. Thank you yet again for sharing your insights into birds, bugs, and Grandview Cemetery. John Shenot Fort Collins
