Superb Afternoon at Barr Lake State Park

October 7, 2011

Richard Stevens:

After two weeks of owling every night, Bryan and I resigned after hiking around in 24+ mph winds Thursday night into Friday morning. I dropped Bryan off in Brighton and got a ride over to Barr Lake (Adams County). Rebecca dropped me off and went on to chores.

Surprisingly, winds were 4 mph or less at Barr Lake from 3:00 pm to 6:15 pm. During this time, I had planned to walk from the Visitor's Center to the Old Stone House (approximately 3 miles). Several flocks of birds changed those plans.

A Field Sparrow had been spotted earlier behind the Visitor's Center. So many sparrows were west of the building; it took 1.5 hours to look at them. The final count was 81 White-crowned Sparrows, 3 Chipping Sparrows, 1 Harris's Sparrow, 1 Savannah Sparrow and a Field Sparrow.

Not one of my regular hikes, I walked along the southern weedy edge of the canal from the Visitor's Center to the first tall tree. The Harris's Sparrow was in the pile of dead brush (perhaps 60 yards southwest of the Visitor's Center).

While, another 20 yards farther west, I saw the Field Sparrow with dozens of White-crowned Sparrows below the top of the canal. This flock eventually reversed directions and ended up back behind the Visitor's Center. While I was able to get fair looks at the Field Sparrow three times, I could not tell if it was the one banded earlier in the week.

Returning to the Visitor's Center, I relocated the Harris's Sparrow and a dozen White-crowned Sparrows, which were last observed flying south and landing in the only tall Rabbit Brush south of the Visitor's Center.

Another interesting bird kept flying out of the grasses and landing deep in the grasses several times. It turned out to be a Chestnut-collared Longspur in basic plumage.

One House Wren stayed around the feeders. A female/immature Lark Bunting was on the ground below the Visitor's Center feeders. When I went inside to record the sparrows on their white board, a male Wilson's Warbler flew into the western window. Mostly the Wilson's Warbler is mentioned as he was the only warbler I found during the visit.

I then spent an hour wandering around the banding area. As expected, most birds were found at the southwestern edge of the area (direct sunlight on the trees). A Great Horned Owl was watching from the tall cottonwoods.

A Cassin's Vireo eventually flew to the tree-covered finger of land that juts into the lake. Over sixty Chipping Sparrows and four Black-capped Chickadees were also in that area.

With little songbird activity, I changed to shorebird mode and walked to the north end of the sand/mud spit. Shorebird action was slow however did include: 1 Black-bellied Plover, 3 Pectoral Sandpipers, 1 Sanderling, 4 Western Sandpipers, 4 Baird's Sandpipers and 6 unidentified peeps (not Least Sandpipers).

Other birds on this spit included 18 Snowy Egrets, dozens of American White Pelicans, Ring-billed Gulls, 8 California Gulls, 5 Double-crested Cormorant and a Great Blue Heron.

One other interesting bird was spotted halfway between the banding area and the first Osprey nesting platform. The bird flew up seven times and disappeared in the weeds 20-25 yards from the shoreline. This bird was quite dark with a hint of rufous color from head to tail (slightly darker wings). It was a very small bird with a short tail and needle like bill. Too big to be a House Wren, It showed no white, just plain dark rufous, streaked belly and flanks. It had to be a Winter Wren (although seemed out of place)!

I called Rebecca for a ride about 6:00 pm. We met at the boat ramp area and then went looking for Short-eared Owls along the DIA Owl Loop. None appeared tonight. Two Burrowing Owls were seen at the prairie dog village (3.4 miles east of Tower Road & 96th avenue).

Rocky Mountain National Park and Highway 34

October 6, 2011

Richard Stevens:

Bryan Ehlmann and I tried to get up Trail Ridge Road, Rocky Mountain National Park. We wanted a last view of White-tailed Ptarmigan in the park before Trail Ridge Road is closed for the season. However, the road was closed at Rainbow Curve due to snow.

We climbed to the top of the old ski area in Rocky Mountain National Park and sat until dark before dropping back down to our car.

One Boreal Owl was heard on the trip down.

Two Northern Pygmy-Owls responded to recordings played when we drove down highway 34 back toward Loveland.

During our recent owling treks (September 28 to October 6), we would set up "listening stations" (see recent articles in "Colorado Field Notes") when below 10,000 feet. Most exploring for Northern Saw-whet Owls and Northern Pygmy-Owls. When we finally got the time to listen to the recordings, we had attracted 3 Northern Saw-whet Owls and 2 Northern Pygmy-Owls.

Loveland Area and Cow Creek Trail

October 5, 2011

Richard Stevens:

This afternoon, Bryan Ehlmann and I visited some new friends in the Loveland area (Larimer County). They put us on to three Northern Saw-whet Owls (spread over two Locations).

We set up our "listening stations" and found another two Northern Saw-whet Owls southwest of Loveland.

Then we hiked Cow Creek Trail in Rocky Mountain National Park. We heard two Northern Pygmy-Owls. No Flammulated Owls called tonight. A New York birder heard one south of the Cow Creek Bridge on Monday night.

Trap Park

October 4, 2011

Richard Stevens:

We stuck to our plan of hiking into areas, waiting until dark, then walking back out and owling. This afternoon, we chose the Trap Park (and Creek) trail (Larimer). It is a long hike to the end; however is relatively "flat" mostly 10,000 to 10,200 feet in elevation (length approximately 3.0 miles). We did detour to Flat Top Mountain which was quite a climb (although only 355 feet and 0.7 miles).

Winds were 5-9 mph tonight. Owling was not as successful. We only heard two Boreal Owls. Bear signs (clawed Aspen trees) was quite numerous. No Bear sightings (not that we care to run into any) since they can outrun and out climb us.

One American Three-toed Woodpecker was the daytime highlight.

Teller City and Jack Creek

October 2-3, 2011

Richard Stevens:

Our choice for birding and owling this afternoon was the old Teller City Ghost Town (Jackson County). The history of the area as a Silver Mining town is quite interesting. For a short period of time, over 200 miners and "friends" occupied the town. Remnants of the old town are highlighted with a self-guiding tour. Parts of the "house of ill repute" still stand.

Two American Three-toed Woodpeckers were heard drumming along the northern trail. The resident Northern Pygmy-Owl called at dusk; however again eluded our eyes.

After dark, we made one of our longest hikes. The Jack Creek trail hike as a little over 6.0 miles (one way), elevation 9300 feet to 10,800 feet.

Winds calmed down tonight (well most of the night); skies were mostly clear.

Boreal Owl count was good. We took waypoints on 9 owls. There is no way to calculate how many of the total Boreal Owls were in the area covered. Surely, we did not find all or perhaps 50 percent? It would be great to be able to know or calculate.

It should be mentioned that driving from highway 14 to Teller City requires a 4-wheel drive vehicle. I would not attempt it in any car that I liked or wanted to keep. It is not a good place to break down either (I expect AAA does not visit or charges a fortune for retrieval).

Our owling for the night was not over. We decided to sleep in our car back in the Colorado State Forest. For the third time in the last 10 years, both a Flammulated and Boreal Owl were heard at 4:30 am! One of my favorite places to camp!

Laramie River Road & Zimmerman Lake Loop

October 1, 2011

Richard Stevens:

Bryan Ehlmann and I went birding up Laramie River Road today. We ran into a Wyoming birder who reported a Pileated Woodpecker at the Tunnel Campgrounds (Larimer County). If we could photograph or get a decent sighting, the bird would be a first state record.

Unfortunately, no Pileated Woodpecker was found in a 3-hour search. There have been four reports of a Pileated Woodpecker in Colorado. All were single birder sightings; none has been confirmed.

Tunnel Campgrounds did have a male American Three-toed Woodpecker and 2 Townsend's Warblers as consolation prizes.

Next, we hiked the Zimmerman Lake Loop Trail (Larimer). We were not disappointed. Two White-winged Crossbills circled overhead between the trailhead and the lake!

Our plan was to hike up to tree line (11,005 feet) wait until dark and return to Zimmerman Lake (10,495 feet), then continue to Highway 14.

We enjoyed a night of almost no wind and clear skies. Up there, stars appear to be in the millions! The eastern ridge must block most northeastern winds; we could have heard a pin drop!

Owls did not disappoint us either. We found/ heard only three Boreal Owls, (no reason to hit the owls with a spotlight and disturb them, we only wanted to get a count). There might have been a fourth, too close to number 3 to be sure.

We enjoyed the night so much, that when reaching our car, we decided to hike up to Montgomery Pass. The trail follows an old jeep trail and is not difficult to follow in the dark. The trailhead is just a little north of the Zimmerman Lake Loop trailhead.

I was familiar with this trail as it was climbed when I was trying to hike the 300 highest passes in Colorado. By the way, I only have three to go and I will have accomplished that!

Again, we relished the calm night and owls. The forest is quite noisy even at night! Figuring out what was calling is always interesting and challenging! In the mammal category, several bull elk were heard bugling.

At least another 3 Boreal Owls responded to our recordings. Montgomery Pass (11,004 feet) was reached about 4:00 AM. The return trip was just as pleasurable.

Owling Canadian Fork River

September 30, 2011

Bryan and I continued our owling. This night we hiked deep into the Colorado State Forest along the Canadian Fork River Road (Jackson County). We found three Boreal Owls around Kelly Lake and took GPS waypoints.

Weather continues to be cooperative. We are running into mild wilds, star filled, clear nights. Bear activity appears to have increased. We found many Aspens ripped up by bears. Are they sharpening their claws? No bear sightings yet.
