Return to Rocky Mountain Arsenal

September 19, 2009

Bryan Ehlmann:

Richard Stevens and I returned to Rocky Mountain Arsenal, Adams County. We wanted to see how many of last week's birds remained and to see if any new migrants had arrived.

We arrived right when they opened and our first stop was to play owl recordings at the Governor's Row. No owls answered; the area is off limits to hikers, so only an auditory search is possible. Both Barn Owls and Long-eared Owls have been found here in the past.

We circled Lake Ladora, and then hiked to the end of the Rod and Gun Club trail and finally did the Havana Ponds trail.

Birds were few. We found a couple of Lincoln's Sparrows east of Lake Ladora; 61 Chipping Sparrows south of the lake; a Brown Thrasher was along the canal between Lower Derby and Ladora (this was the area of the Cassin's Vireo and Northern Waterthrush last weekend).

Our highlight was a female/1st year American Redstart at the end of the R & G Club trail.

No owls, eagles, falcons were found.
