There is a mini fall out at my house right now. I had some good looks at a male Blackpoll Warbler in a cottonwood as it was singing. Other birds seen were;
Western Tanager 1
Chipping Sparrow 100+
Yellow-rumped Warbler 15
House Wren 1
Bullock's Oriole 3
Pine Siskin 4
Yellow Warbler 2
At McMurry Natural Area highlights were Northern Waterthrush (2), Western Wood-Pewee, and a probable Dusky Flycatcher, Black-headed Grosbeak, Spotted Sandpiper and a few Yellow-rumped Warblers.
Good Birding
