Cherry Creek Reservoir & Barr Lake

May 25, 2009

Richard Stevens:

Again as I returned from owling all night I drove over to Cherry Creek Reservoir (Arapahoe County). At 6:00am and again at 7:00am, the Least Tern was not at yesterday's new wetlands pond southeast of the model airplane field. Eight American White Pelicans, 2 Spotted Sandpipers, 3 Snowy Egrets, one Greater Yellowlegs, one Lesser Yellowlegs, and 7 Killdeer were there.

I ran into Jerry Petrosky and we circled the reservoir in search of the Least Tern; without success. Note: it was later found by Kirk Huffstater flying around the southwest corner. We had searched that area and only found American White Pelicans swimming around. The sandbar was completely covered by last night's rain.

I was glad to see that the 3 Black-chinned Hummingbirds had made it through the rain and hail storm. The hummingbirds perch and sing from the taller and barer trees south and east of the wooden fence around the Ranger's Office.

We walked down to the 12 mile beaver pond. Yesterdays, storm had risen the water level there also. Most of the mudflats were covered; again no Least Tern.

The bird population had changed much since my visit on Monday, May 18th. Not one grosbeak flew around or sang. Many male American Goldfinches and Northern Flickers were about flashing their "new coats" to any nearby females.

The southeast sand spit was also mostly covered. No sandpipers were around today; just 39 Pelicans and a couple of Killdeer.

We searched many of the cattails around the park for a Green Heron; without success. A quick walk through the woods from the Mountain Loop to the Lake Loop did not find any uncommon birds.

We then headed over to Barr Lake. Similar birds were found as on Friday, May 22nd. Highlights were:

Magnolia Warbler: moving east from mile marker 7.4.
Northern Waterthrush: along the west side of the Pioneer Trail
Olive-sided Flycatcher: mm 8.2
Tennessee Warbler: mm 3.0

Strange miss; I have not found one Empidonax species Flycatcher yet this year at Barr Lake?

In the afternoon, Rebecca Kosten and I found ourselves at Welchester Tree Park. Birding was a little slow however we did count 9 Spotted Towhees, 3 Gray Catbirds, and 4 Yellow Warblers.

The highlight was an Ovenbird that ran across the path on the north side of the creek (where the large cottonwoods form a tunnel. A female Lazuli Bunting was at the northeast corner of the park.

The Least Tern was back at the Wetlands Pond southeast of the Model Airplane field at Cherry Creek Reservoir at 7:00 pm.

We called off our Boulder County Owling for tonight. The rain was too persistent; not conducive to finding owls.
