Rich Stevens' Bird Trips
September 1999
Wheat Ridge Greenbelt 9/29
I birded Wheat Ridge Greenbelt (Jefferson County) for five hours.
At 7:05am there was a flock of 94+ Yellow-rumped Warblers plus one male Magnolia Warbler
feeding in the cottonwoods around the playground area.
At 8:15am I spotted a Northern Waterthrush just east of the Tree Bridge.
At 9:10am the flock of Yellow-rumped Warblers was just west of Prospect Bridge and
south of Clear Creek. This time I picked out the Magnolia Warbler and
two Townsend's Warblers. Also with the flock was a Virginia's Warbler.
At 9:30am a field trip of 300 school children showed up and I found few birds after that.
Also observed:
Orange-crowned Warbler (14)
Wilson's Warbler (2)
Blue Grosbeak (female)
Red-naped Sapsucker (male, first bridge of Tree Bridge trail)
Western Wood-Pewee
The Plumbeous Vireo observed on Monday 27th during a three hour search, could not be re-found.
I then hiked the two miles east to Johnson Park (another two hours).
The only birds observed at Johnson Park were three Orange-crowned Warblers.
Half way to JP, just east of Anderson Park, there was a Townsend's Warbler
accompanied by 34 Yellow-rumped Warblers.
It was a beautiful day after yesterdays snow (3 inches at my house on the plains).
Wheat Ridge Greenbelt 9/27
A quick trip (3 hours) to Wheat Ridge Greenbelt produced few bird sightings.
There was a Plumbeous Vireo sighted east of the eastern end of chain link fence.
Temperatures were around 50 degrees and it was breezy.
On the way home, I checked on the Burrowing Owl Colonies.
They should be moving out any day now!
Burrowing Owls
(2) (3.4 miles east of Tower Road and 96th avenue)
(3) --Picadilly Road; 1/2 mile south of 128th
(2) (Buckley Rd/56th ave; 1.5 miles north of Eagle Bunker)
CoBus Field Trip to San Luis Valley 9/26
Donna Fortney, Sue Dorsey, Bob Demsey and I traveled to the San Luis Valley and
the National Wildlife Refuges at Alamosa and Monte Vista.
We observed 5 Whooping Cranes (WHCR) at Alamosa NWR and many Sandhill Cranes
at both refuges. The best bet for observing the WHCR is to ask at the Ranger's offices
of the refuges for latest WHCR sightings.
At Homelake Wildlife Area and Smith Lake Wildlife Area,
there were few birds. The WHCR's made the trip well worth while!
Birding Eastern Plains 9/23-9/24
I traveled to the eastern plains of Colorado to bird the last two days.

Temperatures were warm and it was windy.

I ran into several other cobirders and we enjoyed a good five hours of birding
at Wheat Ridge Greenbelt. Weather was great with no wind and mild temperatures.

probably a second time 25 yards east of same corner)

A Trip to Colorado Springs 9/16
Donna Fortney and I traveled down to C.S. in search of the possible Inca Dove.
We spent three hours in the general reported area, without a successful sighting.
A trip to Fountain Creek Regional Park did not improve our bird list for the day.
There were many Wilson's Warblers and one Marsh Wren moving around.
A stop at Big Johnson Reservoir added four American White Pelicans and
several dozen Western Grebes and Ruddy Ducks to our day list.
At sunset at Castlewood Canyon State Park (Winkler Ranch),
we watched four Lewis's Woodpeckers flying around the cottonwoods north of the ranch.
A Beautiful Day at Wheat Ridge Greenbelt 9/15
Usually I do not stay in one location all day, but what a beautiful day!
The weather at Wheat Ridge Greenbelt was superb, cool and no wind.

I went to dinner and started home.
However, I could not resist going back to PROW location. No birds observed there.
I ended day by filming a lone Cattle Egret on Prospect Pond and
four Common Nighthawks flying overhead. I had not observed any CONI for
about 10 days and thought maybe that they had all migrated.
I managed to photograph all birds observed but Golden-winged Warbler.
(Probably witness shots only and none of computer quality).
Weld County 9/13-9/14
Monday afternoon on the way to Greeley Audubon Society meeting
I stopped at Latham Reservoir. The Ruddy Turnstone was still
on the south side of CR 48. There were several other species of sandpipers.
Tuesday, I birded Crow Valley Campground (Pawnee National Grasslands)
for five hours. In the first four hours, the only interesting birds observed were
a Townsend Warbler west of campsite #7 and a Red-breasted Nuthatch at campsite #6.
As I was walking to my car, four birders came and asked to see the TOWA.
I went back to campsite #7 and many birds came out of the trees to west.
Cassin's Vireo
Plumbeous Vireo
Townsend's Warbler
Bullock's Oriole
Along with many Wilson's Warblers, two Western Flycatchers, and a Western Wood-Pewee.
There was a second Plumbeous Vireo at the group picnic area.
A Broad-winged Hawk flew over the same area.
Three Short-billed Dowitchers fed in the pond to the north of the campgrounds.
No sandpipers could be found at Latham Reservoir or Beebe Draw Ponds on my way home.

Hunting for Boulder and Larimer County Pinyon Jays 9/11
Looking for a way to escape house chores Saturday,
I took Louise Jones to the Davis home northwest of Lyons.
Thanks much to Davis for being so gracious with his hospitality.
It required a two hour wait for the 25+ Pinyon Jays to come to the feeders.
During that time we observed many species and enjoyed a fantastic view.
The second highlight was a Northern Goshawk, which seems to visit his yard many days.
Other birds:
Evening Grosbeak (one has been visiting for a few days)
Lesser Goldfinch
Red-breasted and White-breasted Nuthatches
Two Broad-tailed Hummingbirds
Spotted Towhee
At least one Pacific Loon was still at Baseline Reservoir today.

It was another beautiful day to bird in Colorado.

I spent five hours hiking twice from the parking area at
the Resident Manager's home to eastern parking area below dam.
Then hiking three times along creek formed by eastern outlet canal:
- Chestnut-sided Warbler (fall plumage; 200 yards north of dam at 7:00am
and 50 yards north of dam at 9:30am)

On the way home, I decided to take 20-mile detour to Latham.
The Ruddy Turnstone was on Weld County Road 48,
east of bridge, west of the two large water pools.
It was 15 feet from the road on grass clumps as I watched for one hour.
There were many other species of sandpipers, including two Pectorals.
However, I struck out in search for Short-billed Dowitcher.
Birding Weld County 9/8
What a glorious day to bird in Colorado.
Temperatures were middle 70's and there was no wind.
Having read about Steve Messick's Buff-breasted Sandpiper at 5:50pm on August 7,
I reached Latham Reservoir (Weld county) at 7:00pm. There were no sandpipers at all.
By the time I drove south to Beebe Draw Pond (Weld County),
it was too dark to distinguish characteristics of the dozen or so sandpipers there.
