Rocky Mountain Arsenal & Frenchmans Creek Wildlife Area

October 6, 2010

Richard Stevens:

Jerry Petrosky and I visited Rocky Mountain Arsenal (Adams County) while we waited for Bryan Ehlmann to get some work done.

At sunrise, we hiked to the Rod & Gun Club bird blind and back. The trees around the bird blind were quiet (no birds and no wind).

On the way back, we found a Nashville Warbler under the tall cottonwood tree along 6th avenue (north of 3rd red buried cable sign, west of Peoria Street). The bird was "with" 3 Black-capped Chickadees and 2 Yellow-rumped Warblers. It eventually moved toward the New Mexico Locust grove to the north.

While standing here, we heard a Virginia Rail and saw a Marsh Wren.

We continued around the east and north side of Lake Ladora. While we were watching a small flock of birds in the Russian Olive trees below Lower Derby Lake, a Barn Owl flew out of the taller cottonwoods. An Eastern Phoebe was among the flock of Wilson's Warblers, Western Wood-pewee, and Dark-eyed Juncos. The Eastern Phoebe eventually flew to the west side of Peoria Street.

When we walked along the outlet canal below Lower Derby Lake, we found a House Wren and Hermit Thrush.

We circled Mary Lake and found an immature Swamp Sparrow along the outlet canal to Lake Ladora. It was with 6 or 7 Song Sparrows. While we played a tape to entice a better look, a possible adult Swamp Sparrow also came out of the cattails.

Bryan was finally ready and we all headed toward Northeast Colorado.

We struck out on finding the Le Conte's Sparrow and Nelson's Sparrow at Frenchman Creek Wildlife Area (Phillips). We did find a Black-throated Green Warbler and Red-breasted Nuthatch at Holyoke City Park (Phillips). We also relocated 3 Field Sparrows at the Lion's Club Fishing Pond.
