More Wanderings Around Denver

January 5, 2010

Richard Stevens:

I cannot come up with an adjective for what a beautiful winter day Tuesday was! Temperatures in the mid 40s and calm winds until about 1:00 pm. Calm before the storm, tomorrow temperatures could be 20 degrees colder and snow predicted.

At 7:30am, I returned to Overland Park Pond and looked for the Barrow's Goldeneye around the Florida Avenue overpass. Not finding it within 50 yards north of the overpass, I walked south the 0.8 miles to the Evans overpass. Still I did not find the duck and started back to my car.

They maybe something said for looking too early in the morning. As I walked north, many ducks swam away from the near shore. They may spend the night along the near shore and escape detection as it cannot be seen from the bike path.

When I got back to Florida Avenue, the male Barrow's Goldeneye was just north of Florida Avenue (and of course, next to my car).

Next, I went over to Red Rocks Park for another look at the Golden-crowned Sparrow. As I was looking for a lazy day, I sat for an hour and watched the birds (from below the southern end of the deck behind the trading post).

The Golden-crowned Sparrow came twice to feed on the seed thrown on the ground by someone (thanks much!, I added seed later). The Chipping Sparrow came for long periods. Many Western Scrub-Jays, Dark-eyed Juncos and Spotted Towhees were there to watch also.

The Golden-crowned Sparrow had some interesting behavior. It would chase one particular female Dark-eyed Junco. Other juncos around the sparrow were not disturbed, but this one female (I watched, it was the same junco on each occasion) would be chased away from the seed. The sparrow chased it long distances along the stone wall and then returned to eat several times. I was left to wonder what was up with that junco?

On the way to 88th Avenue and Colorado Blvd, I stopped at the parking area at Lowell Blvd and I76. I picked up my American Dipper year bird and one Bob Canter sighting!

Headed next to South Platte River to see how many Long-tailed Ducks I could find (up to 4 reported on Monday). On the way over, I stopped and scoped the small open water area of the southeast corner of Tani Reservoir (Hwy 224, east of Platter River). There were hundreds of ducks including the male Barrow's Goldeneye. Also picked up my first Ruddy Ducks of 2010. No uncommon gulls were among the 400+ Ring-billed Gulls and 2 Herring Gulls.

Once at 88th and Colorado avenues, I walked the east side of the river along the fence for East Gravel Lakes. A male Long-tailed Duck was among many Common Goldeneyes, Buffleheads, etc.

Next I walked to the north and west end of West Gravel Lakes. At first, there were no Long-tailed Ducks; after 15 minutes, two immature Long-tailed Ducks swam from around the dam's tower. The Long-tailed Ducks would dive for up to a minute and only surface for 5 seconds. It took a while to determine how many were there. I stayed for another 30 minutes to see if the adult female would show; she did not.

Needing more exercise (not really) I walked the west side of the Platte River down to the green and white tower/tank. Hoping to find the female Barrow's Goldeneye I observed recently (never did) I found a female Long-tailed Duck on the Platte (where river is split by "island/sandbar" whatever it would be called).

Four Long-tailed Ducks! Great stop! I digiscoped all but do not except anything but witness shots as most were through chain link fence and long distance away.

Update: After reviewing the photos, I believe the Long-tailed Duck on the Platte River was the same female observed on East Gravel Lake. It did fly up and head toward Tani Reservoir and could have circled back to East Gravel Lake (just North of Tani).

I ended my birding day back at Barr Lake State Park, again missing the Winter Wren reported last Sunday.

Front Range Jaunt

January 4, 2010

Richard Stevens:

Instead of getting sleep (who wants to do that) I drove the DIA Owl Loop before sunrise. No owls. Raptor count was 2 Red-tailed Hawks, 3 Rough-legged Hawks, 1 Ferruginous Hawk and a pair of American Kestrels.

I searched about an hour for the Winter Wren reported at Barr Lake; without success. Along the canal below the dam I did find, 9 Song Sparrows, 1 Virginia Rail, 1 Wilson's Snipe and one Marsh Wren.

Then I took off for Larimer, Broomfield and Boulder County jaunt to bolster my 2010 year list. With many places to visit and only about 8 hours of daylight, I had to skip the Kodak Watchable Wildlife Area (report of a Red-shouldered Hawk). My mistake as the Red-shouldered Hawk was relocated on 1/6!

Grandview Cemetery, Fort Collins (Larimer) It took about 10 minutes to find the male White-winged Crossbill at the southern end of the cemetery. Once in awhile a quick search is nice!

Simpson Ponds Wildlife Area (Larimer) The Rusty Blackbirds have moved on to private land. I was fortunate to find someone to allow me to check it. Could not find any Rusty Blackbirds along the river or side streams at Wildlife Area. Update: Two Rusty Blackbirds were relocated on the Wildlife Area property on 1/5.

Cattail Pond, Loveland (Larimer) Drove by on my way to Dry Creek Reservoir. Did not see any Great-tailed Grackles but I did not search for them either.

Dry Creek Reservoir (Larimer) One Long-tailed Duck and 7 Greater Scaup. Had to wait for Long-tailed Duck to swim from behind the hill to southwest. Private property, no access.

Erie Reservoir (Boulder) Many gulls but no uncommon ones. A pair of Red-breasted Mergansers was year birds.

Prince Lake #2, Thomas Reservoir (Boulder) Nothing but snow covered ice.

Parkside Center Pond (Off Lowell Blvd, Broomfield) About 100 gulls including a 1st cycle Thayer's Gull. Nice looks, close to road.

Valmont Reservoir (Boulder) Spent the last hour of daylight scoping the gulls. Tens of hundreds flew in during that time. A truck drove down the dirt road and honked horn. Gulls flew up, giving good looks and landed on ice even closer to me!

I thought that at the distance of my location I would only be able to pick out large white gulls and dark ones. Two 1st cycle Thayer's Gulls flew up and were somewhat easy to ID. The 1st cycle Great Black-backed Gull came in also. Hundreds of gulls were too far away to ID.

Note about entrance at Red Deer Drive. I went into office and asked what time they closed as gate is locked. One person said it was a good idea to not be in there after 4:00 pm. Another person said they work until 5:00 pm. I noticed later that the gate was locked at 4:30 pm, so it was lucky that I parked outside of the gate and walked extra distance!

After dark, I checked out some Boulder County owl spots. Long-eared Owls on private land. No Northern Pygmy-Owls, but I did hear an Eastern Screech-Owl along the South Mesa Trail (across from Doudy Draw).

First Week of 2010 Birding

January 6, 2010

Bryan Ehlmann:

Five of us returned to Denver this morning hoping to beat the oncoming winter storm; which we did!

We stopped at Flagler Reservoir (Kit Carson), found almost no birds moving around and continued west.

January 5, 2010

Bryan Ehlmann:

Eight of us conducted the Bonny Reservoir (9th consecutive) Christmas Count today. Details in February's "Colorado Field Notes".

Highlights included many owls (Eastern Screech-Owl, Long-eared Owl, Short-eared Owl, Great Horned Owl), Red-bellied Woodpeckers, Eastern Bluebirds, Winter Wren and Common Redpoll!

January 4, 2010

Bryan Ehlmann:

Ten of us conducted the Wray Christmas Count today. Details in February's "Colorado Field Notes".

Highlights included Harris's Sparrow, White-throated Sparrow, Northern Cardinals, Common Redpolls, Eastern Screech-Owls, Long-eared Owls, Short-eared Owls and Wild Turkeys. Best bird(s) were 2 Greater Prairie-Chickens, which are difficult to get on any Christmas count.

January 3, 2010

Bryan Ehlmann:

Eight of us conducted the Lamar Christmas Count today. Details in February's "Colorado Field Notes".

Highlights were Harris's Sparrows, Red-bellied Woodpeckers, Northern Cardinal and Short-eared Owls.

January 2, 2010

Bryan Ehlmann:

Six of us traveled to Lamar today.

We drove roads north around the Falcon area (including Elbert Road) searching in vain for the Snowy Owl reported last week.

A drive around Rocky Ford found 2 White-winged Doves and one Inca Dove at the traditional locations.

We searched south of Las Animas at the infamous "secret bird feeding station". Nothing uncommon was found.

At dusk we searched the Upper Queens Reservoir area for Short-eared Owls; without success.

First Bird of 2010, Jackson County

January 1, 2010

Richard Stevens:

Four of us started 2010 earlier by cross country skiing in the Colorado State Forest. Our first bird of the year...........Boreal Owl! My second best "first of the year bird" ever.

On the way back to Denver, we missed Northern Pygmy-Owls up Rist Canyon (Larimer County), but added two Long-eared Owls to our 2010 list at a private ranch in Boulder County.

Later in the day I went searching for the Lewis's Woodpeckers of Louviers (Douglas County); without success. I continued to Sedalia and found one of the American Three-toed Woodpeckers West of Sedalia, 0.2 miles east of Rampart Range Road.

Few birds moved about Cherry Creek Reservoir (Arapahoe). The lone American White Pelican was still there. A second Pelican had been there for a day or two, but has now vanished?

The mystery of the 2nd Pelican may have been solved. The first Pelican which has been around for weeks was being eaten by a Bald Eagle on January 3rd. Perhaps the other Pelican suffered the same fate?

A few Great-tailed Grackles continue to hang around the south end of the Tree Nursery at 152nd Avenue and Picadilly Road (just north of Barr Lake, Adams County).

Colorado State Forest Birds

December 31, 2009

Richard Stevens:

This afternoon we found a few Rosy Finches at the Colorado State Forest Visitor's Center. Plenty of Pine Siskins, Mountain Chickadees, a pair of Pine Grosbeaks and a male Evening Grosbeak were seen.

Our search for Greater Sage-Grouse yesterday was a bust; however, we enjoyed the mountains!

Jefferson County birding

December 30, 2009

Richard Stevens:

I took two out of state birders up to Reynolds Park and Pine Valley Ranch Park today.

We heard a Northern Pygmy-Owl south of the larger (western) parking area for Reynolds Park.

At Pine Valley Ranch Park we briefly saw a American Three-toed Woodpecker up the hill (south) of Pine Lake. No Northern Pygmy-Owls could be tempted to respond to my recordings.

Clear Creek and Summit County

December 29, 2009

I took two out of state birders into the mountains to search for Rosy Finches and White-tailed Ptarmigan. We found Rosy Finches, but struck out on Ptarmigan on Loveland Pass.
