I was lucky enough to be invited along on a Weld County trip by Doug Shoffner and a mutual new birder friend and her 9 year old daughter - also a budding birder! We ended up with 71 species.
After great looks at singing Grasshopper Sparrow and the first of hundreds of Lark Buntings at Hwy 14 and CR 51, it was on to Crow Valley Campground. Best birds were a 1st year male (AHY) American Redstart and a Red-headed Woodpecker with bright birds like a female Western Tanager, American Goldfinches, Orchard and Bullock's orioles, a male Black-headed Grosbeak, Yellow Warblers and a less bright Brown Thrasher and endlessly singing Northern Mockingbird wowing our new birders. Unfortunately, I couldn't turn any of the Swainson's Thrushes into Gray-cheeked.
Just up the road at the Work Center we had female Summer Tanager and another (or same?) Red-headed Woodpecker. The Crow Creek bridge over CR 77 had a lot of activity but nothing unusual until a Swainson's Hawk dove through and excited everything.
