Return to Plaster Reservoir

November 16, 2009

Richard Stevens:

While out doing chores, Rebecca Kosten and I returned to Plaster Reservoir (Broomfield County).

As we walked by the footbridge east of the Russian Olive Tree Grove east of the reservoir, a Marsh Wren was rattling away. I played a recording for just 5 seconds and the Marsh Wren flew up from the cattails and landed about 15 feet away!

We waited about 1.25 hours and were about to leave when the Harris's Sparrow came from the fir tree north of the green house (north of Russian Olive Grove). It first landed in the tree with red berries (north of the swing set at the green house) and then flew over to the blue house looking feeder south of the blue home (north of R.O. Grove).

While we waited a male and 5 minutes, later a female Northern Harrier flew along the cattails and creek. American Goldfinches, Dark-eyed Juncos, and House Finches also visited the blue colored feeder.

A dark morph Red-tailed Hawk stood in the cottonwoods along the east side of Plaster Reservoir.

Later, I walked the southern edge of Plaster Reservoir where I found a Great Horned Owl at the western end of the trees. A second Marsh Wren responded when I played a recording at the cattails there.

Waterfowl on the lake included: Ring-necked Ducks, Eared Grebes, American Coots, Redheads, and American Wigeons.

Later, we relocated the 2 Common Loons off the boat ramp at Barr Lake (Adams). At least 38 Great-tailed Grackles were around the house south of the Tree Nursery at 152nd and Picadilly Road (just north of Barr Lake).
