Rocky Mountain Arsenal - Adams County

[JBreitsch - Denver]

I spent an hour and a half driving/walking through the arsenal this afternoon.  Mostly it was walking on the west side of Lake Ladora.  There was a total of 55 species, with a good variety of water fowl and sparrows.  Highlights include (in the order seen, so this will be fairly random):

 

Franklin's Gull

Great Horned Owl on nest with two owlets

Loggerhead Shrike

Vesper Sparrow

Sage Thrasher

3 species of swallow

Eared Grebe

Western Grebe

Say's Phoebe

Ruddy Duck

Canvasback

Savannah Sparrow

Marsh Wren

Turkey Vulture

Orange-crowned Warbler

Yellow-rumped Warbler (both types and a possible intergrade)

Mountain Bluebird

Lincoln's Sparrow

 

Hopefully, I'll have a picture or two up later tonight.  Most of the sparrows were skulking, so who knows.
