Aurora Reservoir and Rocky Mountain Arsenal

March 15, 2009

Richard Stevens:

I rode my mountain bike around Aurora Reservoir (Arapahoe County) this morning. Temperatures warmed up nicely; winds were mild.

The Say's Phoebe reported yesterday was not found. The several hundred gulls were mostly Ring-billed with a few Herring and 2 California in the mix.

In the afternoon I revisited the east side of Rocky Mountain Arsenal (Buckley Road). No Burrowing Owls flew in during the night or early this morning. There were no Burrowing Owls seen along the DIA Owl Loop (Adams County).

Larimer & Adams Counties

March 14, 2009

Richard Stevens:

Gary Weston and I birded Larimer County today. Temperatures may have reached the 50s; winds were mild to calm.

We waited at Wellington Wildlife Area before sunrise for Short-eared Owls; none flew around this morning. Three Long-eared Owls were found in the northeastern windbreak. We wanted to check because today (Saturday) is the last day the property is open to the public until July 15th.

Next we drove south to Fossil Creek Reservoir and Swede Lake. In two hours neither last week's Eurasian Wigeon or Greater Scaups could be found. There were no geese to speak of around the property.

We checked as many of the bodies of water around Loveland as time allowed in search of uncommon gulls. A Glaucous Gull was found on the east side of Donath Lake. After 10 minutes, it took off and flew west. No luck was had at Duck Lake, Horseshoe Lake, Boyd Lake, Lake Loveland, Windsor Lake, Timnath Reservoir, and a few others.

In the afternoon Rebecca Kosten and I hiked the east side of Rocky Mountain Arsenal (Buckley Road from 56th to 88th avenues in search of an early Burrowing Owl arrival; without success.

The 8 mile round trip is a nice exercise but too time consuming at 3.5 to 4 hours. We are going to have to tune up our mountain bikes for future treks.

There was no wind at all and once the hum of the car tires on Pena Blvd (500 yards to the east) was ignored we listened to singing Western Meadowlarks, an occasional scolding by an American Robin, and the ranting of 3 flocks of European Starlings (totaling 341 birds).

A flock of 81 Dark-eyed Juncos (Oregon, Pink-sided, Slate-colored) near the creek was joined by 2 White-crowned Sparrows, 2 Song Sparrows, and 5 American Tree Sparrows.

Raptor sightings included 1 Prairie Falcon, a pair of American Kestrels, 2 Rough-legged Hawks, 1 Ferruginous Hawk, and 1 Red-tailed Hawk.

There were no Burrowing Owls along the DIA Owl Loop either. The immature Rough-legged Hawk was in the same spot as yesterday. The Ferruginous Hawk stood on the telephone poles where 96th avenue turns east from north of the Prairie Dog Village (at 3.4 miles east of Tower Road).

March 14 is my early date for a Burrowing Owl in Adams County. Most first sightings are between 3/25 and 3/30.

DIA Owl Loop

March 13, 2009

Richard Stevens:

Early in the morning I tried my luck at finding owls at riparian areas in Morgan County; without success.

A stop at Brush Wildlife Area (Morgan County) relocated the pair of Red-bellied Woodpeckers. The Eastern Screech-Owl found several weeks ago did not cooperate today.

Long-eared Owls can still be found at Jackson Lake State Park. Not much else was found though plenty of American Robins flew around.

In the afternoon I drove the DIA Owl Loop (Denver International Airport, Adams County) to see if any Burrowing Owls have arrived; none were found. I did see a Ferruginous Hawk flying over the Prairie Dog Village (CR 96 at 3.4 miles east of Tower Road).

A Rough-legged Hawk stood on one of the road signs.

Another Search for Eastern Birds

March 12, 2009

Richard Stevens:

At first light I was back at the Yuma County Road 45 Greater Prairie-Chicken lek. Several male birds eventually decided to try their luck at attracting a female; without success.

I birded around Wray (Yuma) afterward and visited the yards of three friends. Northern Cardinals visit all of their yards on a regular basis!

A drive on the country roads east of Wray found few birds. A couple of flocks of White-crowned Sparrows and several Song Sparrows were just about it. Again no Eastern Meadowlarks or uncommon sparrows (such as Field, Harris's, or White-throated) were observed.

A White-throated Sparrow was relocated at Sandsage Wildlife Area. I tried to locate the Eastern Screech-Owl heard last night; without success (have not figured out where he spends the day?)

More on the Eastern Plains

March 11, 2009

Richard Stevens:

I returned to Hale Ponds area (Yuma County) three hours before sunrise and hiked along the Republican River to Yuma County Road LL.5. I eventually found (heard) 4 Eastern Screech-Owls along the trek.

By the time I reached CR LL.5, it was around sunrise and sparrows started to move about CR 4. A Harris's Sparrow flew across CR 4 (near the old restroom area) and dived into the brush. A Northern Shrike was perched on the telephone wires east of the large cottonwood grove.

Temperatures were again in the low 40s; winds however were calm. I headed north to search for Eastern Meadowlarks and other uncommon birds. While I found two possibilities for an Eastern Meadowlark, neither called or sang to confirm that.

While walking along a section of CR 9 a rancher stopped to see what I was doing. He talked about these bright red birds visiting his feeders. The description suggested Purple Finches and he took me back to his ranch. Sure enough, two adult male and a female Purple Finches came by. He believed that the Purple Finches first showed up the day before Christmas.

I continued my tourney by driving the country roads along the eastern border of Colorado. While driving the 2 miles of Yuma CR RR south of Highway 36 a flock of sparrows caught my attention. A Vesper Sparrow appeared among the White-crowned Sparrows popping up from the field.

Sandy Bluff State Trust Land was closed to visitors. I stopped a played an Eastern Screech-Owl recording in an attempt to attract some sparrows. White-crowned and American Tree Sparrows flew up to take a look. An Eastern Screech-Owl answered the playback.

I always enjoy stopping at the historic Beecher Island. Terry Johnston does an interesting take of its history in one of his books. While trying to photograph a Say's Phoebe perched on a branch I heard the familiar song of Northern Cardinal. A bright red male fluttered about the western end of the property.

Simmons Wildlife Area off Yuma CR 22 is a fine example of eastern prairie land. Several dozen sparrows (including another Vesper Sparrow) flew around the property. Forty or so Lapland Longspurs and one male McCown's Longspur were among 200+ Horned Larks.

Back on Yuma CR RRRR, this time 1.6 miles south of CR 23 I found another flock of longspurs among the Horned Larks. Another male McCown's Longspur was picked out of 2 dozen Lapland Longspurs.

I stopped at the end of CR 31 and watched a few White-crowned Sparrows, 1 or 2 McCown's Longspurs, and many Lapland Longspurs fly about.

Just before sunrise I drove to Kevin O'Brien's' Greater Prairie-Chicken lek. No Greater Prairie-Chickens displayed on the lek, but I did see one cross the road. The property owner, a friend I have met on many occasions, came by to catch me up. He has only seen a few Greater Prairie-Chickens on his land in 2008 and 2009. He did give directions to a neighbor's property where he thinks "his" Greater Prairie-Chicken moved. He started running cattle on the land where his lek was located two years ago and thinks that contributed to the Greater Prairie-Chickens move.

I stopped a played an Eastern Screech-Owl recording as I passed Sandsage Wildlife Area. The resident Eastern Screech-Owl answered back nicely!

Colorado Eastern Plains

March 10, 2009

Richard Stevens:

I needed to get out and bird alone and do some walking. It seems that I have been doing too much "car birding" lately. Temperatures were in the 30s or low 40s; at least winds were not as strong as last weekend.

I spent the day walking around Bonny Reservoir (Yuma County) but keeping in mind that I wanted to checkout a possible Greater Prairie-Chicken lek at sunset.

The first three hours I did my 4 mile loop around the Hale Ponds area. Red-bellied Woodpeckers were west of the most eastern pond and also along Yuma County Road 4.

A Brown Thrasher was seen in thickets near the driveway of the first ranch west of Hale Ponds. These bushes have been quite good for Harris's Sparrows and other sparrows in the past. A flock of 9 White-crowned Sparrows and 17 American Tree Sparrows were all that were here today.

Long-eared Owls can still be found wintering in the Hale Store windbreak. Having made a count earlier this winter, I only walked around long enough to confirm that at least two Long-eared Owls remain.

Next I walked the gated road along the south side of Bonny Reservoir. Another pair of Red-bellied Woodpeckers and a flock of 7 Eastern Bluebirds were observed along here. The resident Wild Turkey left many tracks and eventually I found 2 of them crossing the road.

From the dam I could pick out 2 Greater Scaup among quite a few ducks and geese. At least two Cackling Geese, many Snow Geese, and at least 2 Ross's Geese were among the hordes.

Finally I walked CR 3 along the northern side of Bonny Reservoir. A pair of Northern Cardinals were west of the campgrounds. The Long-eared Owl observed earlier in winter in the windbreak east of the campgrounds was not found today.

No Burrowing Owls have arrive yet at the Yuma County Road 7 Prairie Dog Village just east of Highway 385. The nearby Greater Prairie-Chicken lek did not have any displaying birds this evening.

First Grouse Trip of 2009

March 3 through 9, 2009

Bryan Ehlmann:

The first grouse trip of the year is on the books. It was a little early to hunt for grouse but Lori and Chuck Wheeling found it to be the only time they had this year for the trip. Sue Ehlmann joined us for a successful trip. We found all the gallinaceous birds on our target list. Even the most difficult one, if you want to guess the answer is below.

March 3
We started out by looking at Rosy Finches at Fawnbrook Inn at Allenspark, Boulder County and then going into the mountains west of Denver. Our first attempt at White-tailed Ptarmigan was a bust. We looked for a good hour and a half, no luck.

We got a quick look at Barrow's Goldeneyes as we passed the Blue River Water Treatment Plant in Silverthorne, Summit County.

No feeders with seeds were found in Kremmling, Grand County and we drove up to Rabbit Ears Pass where American Three-toed Woodpeckers were also missed.

At sunset we drove Jackson County Road 26 north of Highway 14. Two Greater Sage-Grouse were found which allowed us to skip the Timberlake Lek north of Craig.

March 4

Before sunrise we sat at the 20 Road Sharp-tailed Grouse Lek south of Hayden, Routt County. It is definitely early in the season, but we got lucky. Two males displayed on the east side of the road for us!

Our next location was Oxbow Wildlife Area. Again it was early but we hoped to catch an early Sage Sparrow returning to his breeding grounds. Unfortunately neither a Sage Sparrow or Sage Thrasher could be found.

A Cameo-Coal Creek Canyon, Mesa County a Chukar jumped out of the ditch on the west side of the road across from the old stone house.

We started up the Grand Mesa to search for crossbills and owls. It was snowing rapidly when we arrived at the Powderhorn Ski area. A Three-toed Woodpecker was heard drumming below the western end of the upper parking lot.

Taking the advice of Richard Stevens we returned to Denver rather than drive farther up the Grand Mesa and a possible snow storm.

March 5

Too early for Black-throated Sparrows at the Colorado National Monument, Mesa County we drove the subdivision just outside the eastern entrance. At least 21 Gambel's Quail were found walking around just after sunrise.

The monument was slow. Too early for Gray Vireos, Gray Flycatchers, and Warblers, we did hope for a White-throated Swift or two. The view was spectacular; birds were rare.

A Juniper Titmouse was found in the campgrounds. Several Pinyon Jays called from below the overlook but they eluded our binoculars. Finally at the overlook, three White-throated Swifts flew by looking for insects which seemed pretty rare in the cold air.

At Escalante Canyon, Delta County we drove down to Pinnacle Rock to see if the Black Phoebes had returned yet. It did not appear that they had. On the trip out Lori pointed out a Chukar on the rocks just east of the sheep corral.

Confluence Park in Delta added additional Barrow's Goldeneyes, Ross's Geese, and a Tundra Swan to our trip list.

Fruitgrower's Reservoir, Delta had a few ducks and grebes, no shorebirds. Two Lewis's Woodpeckers were in the cottonwoods below the west end at Evelyn Horn's home.

The last hour of daylight was used up at Black Canyon of Gunnison National Park, Gunnison County. On our third pass between the entrance and the Visitor's Center, Lori again with her great eyes spotted a Dusky Grouse about 15 feet off the road. It was about 20 yards west of the road to the campgrounds.

March 6

Before sunrise we drove Gunnison Road 884 toward the Waunita Hot Springs Lek. A Gunnison Sage-Grouse walked across the road; another flew over our heads and over to the lek.

We searched an hour at Tunnel Drive in Canon City, Fremont County for the Golden-crowned Sparrow. Several White-crowned Sparrows and one Rufous-crowned Sparrow were found, but no Golden-crowned.

It was recommended that we drive the Swallows Road just west of Pueblo Reservoir, Pueblo County. The road is known for Curve-billed Thrashers, Sage Thrashers, Shrikes, and Scaled Quail. Only 3 Scaled Quail and a Loggerhead Shrike were recorded today.

We stopped briefly at the marinas at Pueblo Reservoir, Pueblo County. No rare gulls were found in 30 minutes at each marina and we decided to move on.

Few rare birds had been reported at the various southeastern reservoirs and we decided to reach Cottonwood Canyon, Baca County while there was plenty of daylight to bird.

The usual residents were found at Cottonwood Canyon. Added to our trip list: 2 Rufous-crowned Sparrows, 2 Lewis's Woodpeckers, half a dozen Canyon Towhees, 8 Chihuahuan Ravens, and a pair of Mountain Bluebirds.

No Eastern Phoebes or kingbirds were expected and none were found. After dusk we did hear 2 Western Screech-Owls and saw one of them land in a tree above our heads.

March 7

Fourteen Lesser Prairie-Chickens displayed at the Kansas Lesser Prairie-Chicken Lek outside of Elkhart, Kansas.

Being 50 miles farther south than the Campo Lek, Colorado didn't add any migrants to our trip list. A few White-crowned Sparrows, Song Sparrows, and 1 Vesper Sparrow and Western Meadowlarks were around, not much else.

We passed the road into the Campo Lek on our trip back to Springfield, Baca County. The road heading north from there is usually good for Sage Thrashers; it appeared to be too early for them.

A Burrowing Owl was found in the prairie dog village just west of there. A Curve-billed Thrasher was under the trees with the large Swainson's Hawk nest, again not far west of the Campo Lek road off Baca County Road G.

Two Buttes Reservoir, Baca County was quiet. Chuck found a male Ladder-backed Woodpecker along the creek. We couldn't find a Barn Owl or any migrating birds.

Lamar Community College was also quiet. We couldn't find the previously reported Northern Cardinals or Red-bellied Woodpeckers. A female Red-bellied Woodpecker was seen at Willow Creek Park north of the College.

We missed Eastern Screech-Owls at Bonny Reservoir, Yuma County but were rewarded with several short looks at Long-eared Owls.

March 8

Six Greater Prairie-Chickens were watched at a lek on private land in Yuma County. We then drove over to the Yuma County Road 45 Lek where two additional Greater Prairie-Chickens were still displaying.

The stop was a success. We found 2 Northern Bobwhite on the old logs near the old city dump. Since our tremendous snow storms a couple of winters ago, many of the gallinaceous birds took a big hit. Northern Bobwhite seem to have taken the worst of it.

All the great gulls found at Jumbo Reservoir, Logan and Sedgwick Counties appeared to be gone by the time we reached the area. Two Greater White-fronted Geese and many Ross's Geese remained.

We drove the Mountain Plover Loop in Weld County. A few Lapland Longspurs still wander around the short grass prairie. We didn't find any McCown's or Chestnut-collared Longspurs, Mountain Plovers or Burrowing Owls. Crow Valley Campgrounds appeared empty of birds.

March 9

It was our second attempt at finding a White-tailed Ptarmigan. This time the search was a success. A Ptarmigan was found walking around the rocks on the west side of Highway 6 as we scoped the area from the first pullover south of the Summit. Thankfully it saved us from the 0.6 mile climb up the west side to their usual location.

Lori and Chuck has just enough time to make it to DIA and their flight home.
