Birding the South Platte River in Adams County

December 26, 2013

Richard Stevens:

Looking for a hike, I chose the S. Platte River trail north of 88th and Colorado Blvd.

I did not find the four birds reported yesterday by Cathy Sheeter (Rusty Blackbird, Barrow's Goldeneye, Harris's Sparrow and Greater Scaup).

A Long tailed Duck on the reservoir east of the trail (after it turns east to north) was a nice consolation prize. Sorry I cannot remember its name of the reservoir.

Other birds found included White crowned Sparrows, groups of Lesser Scaups, one adult Bald Eagle and only one Red tailed Hawk.

One final sight was a rare American Black Duck..........plastic decoy! I do remember that being there three years ago.

After lunch, I returned to the area and walked the South Platte River Birding Area from 88th avenue & Colorado Blvd south to Highway 224.  Then I backtracked to Clear Creek and walked west to Washington Avenue.  From there, I took the RTD bus back to my car.

Quite a few ducks spend the winter on the South Platte River.  Just about every "common" species can be observed.  It is a great place for photographers to get images of the ducks as the waterfowl get use to people walking by and are not too skittish.

The pair of Barrow's Goldeneyes was observed among many Common Goldeneyes on the Platte River, just upstream (south) of the green/white tower.

A Northern Shrike was east of the Platte River and west of Tani Reservoir.  I looked unsuccessfully for the Harris's Sparrow reported between 74th & 78th avenues. 

Sparrows appear to be scarce this winter at many of the Denver birding locations.  I only found six White-crowned Sparrows on my trek today.

All the reservoirs in the area were ice covered.  These included East Gravel Lake, the three West Gravel Lakes, Dahlia Ponds and Barrington Reservoir #5.  The one exception was the lake north of 88th where I found the Long-tailed Duck (later found to be named Cooley Gravel Pond on my map).

The many gulls standing on the ice at the various lakes were all Ring-billed Gulls.

It was a pleasant hike and a great way to spend this warmish winter day.  Temperatures in the high 40s; winds calm down in the river valley.

Exploring Kit Carson County

December 24, 2013

Richard Stevens:

Today, Bryan Ehlmann, Jacob Washburn, Ray Simmons and I walked around Fairview Cemetery in Burlington (Kit Carson County).  Pine Warblers have wintered here in the past.  Unfortunately, birding was slow today.  We did find a Great Horned Owl (perhaps keeping other birds from moving around) and two Yellow-rumped Warblers.

Three Great-tailed Grackles flew around Burlington (behind McDonald's and park near I70).

Later, we hiked around Flagler Reservoir (Kit Carson).  Two interesting birds were encountered.  A Swamp Sparrow was "called up" from below the dam.  Later Bryan spotted a Common Redpoll among a flock of House Finches (along the eastern side of the reservoir).

Many Rough-legged Hawks, one Ferruginous Hawk and a surprise Northern Goshawk were observed on our drive back to Denver (along Interstate 70).

Weather was quite cold today (temperatures never reached 30 degrees and anemometer readings were 14 mph, gusts to 22 mph).

Bonny Reservoir Christmas Count Week

December 23, 2013

Richard Stevens:

Bryan Ehlmann, Jacob Washburn, Ray Simmons and I visited Bonny Reservoir Wildlife Area today.  The timing was to include our sightings to the Bonny Reservoir Christmas Count (count week, not count day).

We considered our day to be quite successful as we found Eastern Screech-Owls (three locations), two Long-eared Owls, one Short-eared Owl, one Barn Owl and one Northern Saw-whet Owl.  We do not believe our Northern Saw-whet Owl was the same bird reported previously (ours was on private property which we had permission to bird).

Other interesting birds included a Northern Mockingbird, seven Red-bellied Woodpeckers and two Brown Thrashers.

Nearby Hale Ponds (Republican Wildlife Area) hosted a few interesting birds also.  We found two additional Eastern Screech-Owls, Eastern Bluebirds, Red-bellied Woodpeckers and Lapland Longspurs.  The highlight was a Winter Wren near Hale Ponds marsh.

Unfortunately, no Greater Prairie-Chickens could be located.  We also did not find the previously reported Harris's Sparrow.

Southern Colorado Trip

December 20-22, 2013

Richard Stevens: Southern Colorado Trip

December 20

On the way to pick up Bryan Ehlmann at the airport, I drove the DIA Owl Loop and found a Ferruginous Hawk, two Red-tailed Hawks and a Prairie Falcon.  No Short-eared Owls appeared this morning.

Later we picked up Jacob Washburn and Ray Simmons and headed south (Limon to Rocky Ford to Springfield).

A stop in Rocky Ford found many Eurasian Collared-Doves and one White winged Dove.  No Inca Doves, I have not heard of a sighting in Rocky Ford since January 2011.

December 21
Bryan Ehlmann, Jacob Washburn, Ray Simmons and I (along with three bird feeder watchers) conducted the Carrizo Canyon Christmas Count today.  We ended up with a respectable 63 species (however not close to high of 72 species in 2006).

Highlights included a Winter Wren, Western Screech-Owls, a Long-eared Owl, Short-eared Owl, Lewis's Woodpecker (just one), Rufous-crowned Sparrows (2), Eastern Bluebirds, Hermit Thrush (unusual for count) and one Bohemian Waxwing (among 62 Cedar Waxwings).

Misses included: no Barn Owls or Northern Saw-whet Owl this year, no flyover Sandhill Cranes, Northern Shrike but no Loggerhead Shrike, Curve-billed Thrashers lacking, no longspurs (which had been on all previous counts as were Barn Owls), could not find the resident Northern Cardinal this year.

Total: only 4 birders this year, driving miles down to 52 as we only had one vehicle this year, 22 miles walking (mostly by Bryan and myself).  The center point was near CR 8 & CR J so as to include Picture Canyon, North Canyon, Cottonwood Canyon, and Carrizo Creek.

Final count will be published in a future issue of "Colorado Field Notes".

December 22

After spending the night at a friend's ranch in Furnish Canyon our troupe headed back north.  We drove around Comanche National Grasslands at first light in search of Lesser Prairie-Chickens; without success.

A hike to two previous "leks" (by way of open trails, not closed roads) did not find any prairie chickens.  We did encounter a Curve-billed Thrasher, which was missed on yesterday's Christmas Count.

Birding Two Buttes Reservoir (Baca County) is tricky this fall due to flooding and construction.  We did come across the "bird of our trip".  A Carolina Wren was in the thickets below the northern rocky cliffs (below the dam).

We walked around Lamar Community College (Prowers County) in the afternoon.  A male Northern Cardinal with his splendid red colors stood out at the southern end of the College woods.

A male Red-bellied Woodpecker, not quite as brilliant colored, was found at the northern end of the woods.  Other birds included a Brown Thrasher (rare in winter), too many Eurasian Collared-Doves, a White-winged Dove, and White-crowned Sparrows.  No uncommon sparrows (Harris's or White throated) could be found.

A quick detour to the Mike Higbee Wildlife Area just east of town did not find any uncommon sparrows either.

An Enjoyable and Successful Winter Day on the West Side of Denver

December 19, 2013

Richard Stevens:

Bryan Ehlmann and I made a quick trip through the DIA Owl Loop (as I took him to the airport).  After not seeing any owls for a few days, one of the Short-eared Owls was observed flying along the fence line east of the Prairie Dog Town located at 3.4 miles east of Tower Road & 96th avenue.  See map on Colorado Birding Society's website for recent additional locations that it has been seen (http://coloradobirdingsociety.net16.net).

I enjoyed birding Jefferson & Arapahoe Counties today.  Temperatures were slightly cooler than yesterday (mid 40s); winds were mostly less than 5 mph.

I walked around the various Campgrounds at Chatfield State Park (Jefferson/Douglas) looking unsuccessfully for the Brant.  Then met up with Robb Hinds and we hiked the mile or so down the Highline Canal searching for the Winter Wren reported on Sunday.  Directions were vague and we do not believe the correct location was ever found; the Winter Wren was not found.

After returning to the parking area, Trudy (sorry I do not know her last name but am quite grateful), informed us that she had found the Brant (possible gray bellied?) in Campgrounds A.  Robb and I hurried over and relocated the Brant below the hill, north of the Campgrounds.

Eventually the Brant and 60+ White-cheeked Geese flew to the parking area for the handicapped fisherperson's dock.  We rushed over and were able to get nice views of the geese.  The geese were last observed walking south up the asphalt path leading back to Campgrounds A.

On the way home, I stopped at nearby South Platte Park Reservoir and scoped the lake for about 30 minutes.  Two or three Long-tailed Ducks had been reported there and I wanted to try to confirm the report of three.  Unfortunately, I only found two; they were quite a ways off (along the northern shore of this rather large reservoir).

Then I scoped nearby (to the east) Blackrock Lake and relocated two of the seven previously reported Greater Scaup.  My hike did not continue to Eaglewatch Lake (just north of Blackrock) where the remaining Greater Scaup may have been.  Both lakes were ice free.

My final stop was Red Rocks Park (Jefferson).  I threw out seed and the Golden-crowned Sparrow along with three Song Sparrows appeared within five minutes!  Many Dark-eyed Juncos also came out.  The weather was quite nice and no Rosy Finches were flying around (better viewed on inclement days).

An Enjoyable Afternoon at the Rocky Mountain Arsenal

December 18, 2013

Richard Stevens:

We stayed home most of the day doing chores (well I did chores).  Rebecca Kosten and I decided to drive through the Rocky Mountain Arsenal (Adams County) after lunch and relished the 60 degree temperatures and the sunny skies.

On the way over, we stopped at Lakecrest.  No uncommon geese were among the six thousand+ White-cheeked Geese on the ice covered lake.  I did count 23 Ring-billed Gulls.

Both Lake Ladora and Lower Derby Lake were completely ice covered (no birds).  We kept an eye on the feeders north of the Contact Station for 30 minutes.  A total of four Dark-eyed Juncos (no sparrows) made an appearance.  The feeders were full but did not attract any uncommon birds today.  Note: Dave usually fills the feeders on Tuesdays; it usually takes the birds a couple of days to empty (best time to search of birds is early in the week).

Except for a couple of Northern Flickers and one Red-tailed Hawk that was our bird count.  The highlight I suppose was that the Bison were close to the road today (took some nice closeups).

After sunset, I walked the path through the Governor's Row area; no Long-eared Owls were found this night.  We did enjoy one of Colorado's better sunsets (the result of the polluted skies over Denver).

Another Look at Aurora Reservoir

December 17, 2013

Richard Stevens:

Jerry Petrosky, Bill Cryder and I hiked the southern and eastern sides of Aurora Reservoir (Arapahoe County).  Most of the interesting gulls were in Lonetree Cove (mile 3.0) which cannot be seen from other locations around the reservoir.  One can hike down from the southern entrance and reduce the walk to less than 1.5 miles.

One of two Great Black-backed Gulls previously reported two of the six Lesser Black-backed Gulls and two of the ten Thayer's Gulls were observed here.  A dozen California Gulls and 80+ Ring-billed Gulls were also present.

As we returned to the entrance, we noticed a large "whitish" Gull at Senac Cove (mile 2.5, also difficult to see from the swim beach or dam).  We took photos and called the bird the Glaucous Gull that has been around.  Later examining the photos, we decided that it was not a Glaucous Gull but perhaps the possible Glaucous-winged Gull that has been reported on several occasions.

After lunch, Jerry and I drove to a friend's ranch east of Banner Lakes Wildlife Area (Adams County, closed on Tuesday).  Two Long-eared Owls continued at the windbreak surrounding my friend's home.
