Rocky Mountain Arsenal - Adams

A quick trip to the Arsenal this morning produced a Northern Shrike and a nice flock of American Tree Sparrows among the land birds.

The Great Egret is still hanging around with a Great Blue Heron.

On the water, there were most species of winter birds including all three mergansers, Canvasback, Bufflehead, pintails, shovelers, goldeneyes, etc.  

One Common Loon was on Lower Derby Lake.

The most interesting thing for me was the waves of Snow Geese flying south.  At least half a dozen flocks came through in waves, maybe five to ten minutes apart.  Each flock was between 100 and 200 birds, some of which included blue morphs.  They are definitely on their way somewhere.

If someone finds a murrelet somewhere in the Denver area, let me know.  Otherwise, I'm taking the rest of the day off.
