Rich Stevens' Bird Trips
September 2001
Colorado Plains to the Mountains 9/26-28
Wednesday 26
In the afternoon, Bryan Ehlmann and I headed for Flagler Reservoir.
Birding continued to be slow and we located no uncommon birds.
We ended our day hiking around Karval Reservoir Wildlife Area
(Lincoln County). This wildlife area has a small lake with a
bushy shoreline. It has good potential for Short-eared Owls also.
One Field Sparrow was the only uncommon bird found this afternoon.
A Great Horned Owl called in the distance to the west.
Thursday 27
We rose early (5:00am) and decided to search for the autumn colors
(and maybe a few birds) in the mountains. Our trek followed along
highway 94 to Colorado Springs and highway 24 to Antero Reservoir.
One Sabine's Gull was observed flying 100 yards off the south shoreline.
We circled the 3 sides of the reservoir that are public, but found no
additional uncommon birds. Twenty American White Pelicans, a dozen
Double-crested Cormorants, and two Barn Swallows were added to our day list.
A Osprey flew along the shoreline and overhead just before we departed.
Fall colors were as scarce as birds and we headed up Cottonwood Pass
(west of Buena Vista, Chaffee County). While stopping to photograph
Gray Jays, we observed two male and two female Pine Grosbeaks.
This pass may be one of the best for autumn colors for the next week or so.
We thought we were a week late for most higher locations.
We next back tracked to Buena Vista Overlook. A flock of 8 Bushtits
fluttered about the Pinyon Junipers. A Clark's Nutcracker flew over,
but did not stop. Two Pinyon Jays made a brief appearance also
and headed for the KOA campground to the north.
With three hours of light left, I suggested we try and reach the Royal Gorge
(10 miles outside of Canon City, Fremont County) before sunset.
We arrived an hour before sunset and just in time. Two Peregrine Falcons
were flying overhead, chasing the 200 plus White-throated Swifts.
The two Peregrines rapidly zoomed up and down the canyon as we
watched from the photo overlook (just outside of the eastern entrance).
The White-throated Swifts were so quick and I thought there was no way
the Peregrine Falcons could catch one. A few minutes later however a
Falcon came up the canyon and grabbed one of the White-throated Swifts.
The bird then landed 20 yards below as and ate his feast.
Friday 28
Bryan and I lucked out and stayed in a motel just 8 blocks from where
the Eurasian Collared-Doves had been reported earlier in the year
in Canon City. We spent about 2 hours searching for them; without success.
Our next stop was Pueblo City Park (Pueblo County). We parked
at the ball field and hiked downhill to the Arkansas River.
We then hiked east & south for a mile, back tracked and hiked a mile west.
Birds were scarce in the Olive Marsh area (eastward).
We found an immature White-throated Sparrow approximately 3/4 mile
west of Pueblo Blvd Bridge. Two Lincoln's, 2 White-throated,
3 Chipping, and a Clay-colored Sparrow were also added to our list.
On the trip back to the car, we heard one or two Rose-breasted Grosbeaks.
We only observed one male, although thought two were singing. The one bird
may have moved around quickly however in the 15 minutes it was only heard.
One male eventually flew from the cottonwood trees along the railroad tracks
to the trees around the yellow/brown house with red bush, uphill (to the south).
The house is east of the Pueblo Blvd Bridge and west of the trail up to the park.
We stopped at Big Johnson Reservoir (El Paso) and Castlewood Canyon
State Park (Douglas County) on the trip back to Denver.
No uncommon birds were added to our trip list.
Colorado's Eastern Plains 9/24-26
Bryan Ehlmann & I started out the week with great bird finds;
things have slowed down the last two days.
Monday 24
Jackson Reservoir:
We arrived at Jackson at 5:00am and managed to locate the resident
Eastern Screech-Owl. The bird cooperated and called for about 5 minutes.
The best sandpipers were at the southeast corner where we found
the Red Phalarope reported the day before by Leukering. We also
counted 10 Red-necked Phalaropes, 2 Black-bellied Plovers,
23 Semipalmated Plovers, and 7 other species.
Thousands of American White Pelicans are still here and
present quite a spectacular sight!
Prewitt Reservoir:
We next rushed over to Prewitt and decided to walk to the southwest
corner (round trip about 6 miles). From the SW corner, we observed
the Buff-breasted Sandpiper reported several days earlier by Leatherman.
One Black-bellied Plover was also here.
Our trek took us next to the Russian Olive trees below the dam at
the outlet canal east of the manager's house. One immature
American Redstart fluttered about where the canal runs north-south.
As the canal turns east, we found a fall plumage Blackpoll Warbler.
Bryan heard a Red-bellied Woodpecker; however we never did see it.
Brush Prairie Ponds & Brush Wildlife Area:
We hiked both areas for 2 hours each. While we got a count of the
birds here, except for one White-throated Sparrow at Prairie Ponds area,
nothing uncommon was found.
Last Chance Rest Stop:
We arrived just before sunset. The area was quiet.
One Western Tanager was the only uncommon bird.
Tuesday 25
Bonny Reservoir:
We managed to get the Eastern Screech-Owl at Hale Ponds to respond to our tapes.
The usual Eastern Bluebirds and male Red-bellied Woodpecker were at Hale Ponds
along the Republican River. No Yellow-billed Cuckoos were found today or
Wednesday. The only warbler was a Common Yellowthroat (4-mile hike along river).
A second male Red-bellied Woodpecker was observed along the Republican River
0.5 miles east of CR LL.5 & 4. Many Chipping and Brewer's Sparrows were here.
The campgrounds (Wagon Wheel, North Fork, Foster's Grove) were quiet.
Several Red-tailed Hawks flew overhead; no Swainson's Hawks were found.
Two unidentified "Empidonax" species were west of Foster's Grove CG.
The shoreline of Bonny had several Western Sandpipers, Baird's Sandpipers,
and one Least Sandpiper; not much else moved about.
We explored several ranches north of Bonny for sparrows.
Again, nothing uncommon was located.
We ended our day at Hooper Ponds. A second Eastern Screech-Owl
called for us. Birding was slow.
Chipping Sparrows and Brewer's Sparrows seem to be everywhere.
Four Clay-colored Sparrow have been found.
Wednesday 26
Our day started with my favorite 4-mile hike along the Republican River
at Hale Ponds. Our list included the same birds as yesterday.
Two Wild Turkeys crossed County Road 4, 1.0 mile east of CR LL.4.
Burlington was checked for Eurasian Collared-Doves; we did not locate any.
We head next to Flagler Reservoir and then south.
The weather has been superb. Winds are mild and temperatures are
cool in the upper 70s. What a beautiful week!
Rigili Ranch 9/23
I accompanied the DFO people to the Rigili Ranch Sunday.
The temperatures were in the cool 70s and winds were mild.
While birding was slow this day, a visit to the ranch is
quite interesting as there is much potential there.
The highlights of the day for this eastern plains ranch:
A Green-tailed Towhee and a Willow/Alder Flycatcher.
We did kick up a Barn Owl in our six-hour travels
across this 1960-acre ranch.
Other species observed:
Ruby-crowned Kinglet (3)
Burrowing Owl (4+)
Wilson's Warbler (8+)
Yellow-rumped Warbler (23)
Orange-crowned Warbler (2)
Red-tailed Hawk (4)
Immature Dark-morph Red-tailed Hawk

On the 32 mile trip along CO Hwy 2:
Swainson's Hawk (4)
Red-tailed Hawk (2)
Prairie Falcon (1)
Northern Harrier (2m, 2f)
American Kestrel (1)
Last Chance Rest Stop 9/22 Afternoon
Bryan Ehlmann, Sue Dorsey, and I headed for Last Chance Rest Stop
(Washington County) after hearing about Loch Kilpatrick's great
morning there. We wanted to take a nice drive on this beautiful
day and this offered the chance to see some birds.
We spent two hours at Last Chance and did not find the good birds
reported by Loch. The bird of the day was a beautiful male Merlin.
We circled this small group of trees and did not find much until the
last 30 minutes. Birds suddenly appeared from nowhere. A flock of
38 Yellow-rumped Warblers was accompanied by one adult Tennessee Warbler
(gray-head, greenish back, white eye-brow, and white undertail coverts
[unlike yellow undertail coverts of Orange-crowned Warbler]).
We also observed 3 Pink-sided Dark-eyed Juncos, 2 Townsend's Solitaires,
6 Wilson's Warblers (3 males, 3 females), 1 Ruby-crowned Kinglet,
1 Western Tanager (imm/female), 1 Swainson's Thrush, 1 Orange-crowned
Warbler, many White-crowned Sparrows, and 2 Lark Sparrows.
Along the 60 mile drive from Denver, we observed 9 Red-tailed Hawks,
2 Swainson's Hawks, 1 Ferruginous Hawk, 2 American Kestrels, and
4 Northern Harriers (2 male, 2 females).
All in all, we enjoyed a good collection of birds and
nice drive on the Colorado Eastern Plains.
Return to Bluff Lake Nature Area 9/21
Bryan Ehlmann and I stopped at Bluff Lake Nature Area (Denver County) after
spending most of the day at the Denver Museum of Nature and Science.
Many sparrows were observed after we followed the trail as it dropped
downhill and then went south for 1 mile along Sand Creek. The species
list included Song, Lark, Chipping, Clay-colored, and Brewer’s Sparrows.
We returned to the gazebo downhill from the entrance and followed the trail
west. One Orange-crowned Warbler was just north of the larger gazebo.
A Red-eyed Vireo (bird of the day) was 40 yards east of the smaller 2nd
gazebo (and in the willow just north of the trail). This is the location
where Loch Kilpatrick observed his adult Northern Parula on Monday.
Two Wilson's Warblers was here also.
A hike out on the wooden walkway into the marsh added many sandpipers
to our day list. One Pectoral Sandpiper and one Stilt Sandpiper were within
20 yards of the walkway. We also observed 4 Greater Yellowlegs,
2 Lesser Yellowlegs, many Killdeer, and one Spotted Sandpiper.
Cliff Swallows were the only swallows seen today. One adult Bald Eagle
and one Red-tailed Hawk flew over the lake during our stay.
We did not locate the Townsend's Warblers, Northern Waterthrush,
or Northern Parulas reported earlier in the week.
One Western Flycatcher stood sentinel as we exited the
on the west side (opening between wooden and chain link fences).
We scanned unsuccessfully the many Prairie Dog Colonies for Burrowing Owls.
Chatfield Reservoir; Afternoon 9/20
Paul Langendorfer and I enjoyed a pleasant late afternoon at
Chatfield Reservoir. Temperature was around 82 degrees, winds none.
The juvenile Sabine's Gull was flying along the shoreline at the
swim beach at 3:45pm. Several Ring-billed & California stood nearby.
Few birds were found during a 2 mile hike south from the Kingfisher Bridge.
Two Wilson's Warblers were our only warbler sightings of the afternoon.
The Plum Creek Delta Area (southeast corner of reservoir) was the highlight
of our trek. One Pectoral Sandpiper was accompanied by 20 Baird's, 2 Least,
2 Semipalmated Sandpipers, 2 Sanderlings and one Lesser Yellowlegs.
Several dozen Killdeer also walked around the mud flats.
One sub-adult Herring Gull was with many Ring-billed Gulls and a couple
California Gulls. A dozen Western Grebes swam just offshore.
Two Peregrine Falcons flew over the area. One of the birds buzzed
the gulls, sandpipers, and 40 Mourning Doves several times.
We located no terns and did not find the Sabine's Gull at 7:00pm.
NOTE: Added on 9/25
Paul & I first observed the dark-morph juvenile Jaeger at 5:00pm.
The bird flew over our heads (10 yards to the north) and then away
50 yards, turned 90 degrees, then landed on the shoreline 150 yards away.
Unfortunately, boaters decided to land 20 yards from the bird
before Paul and I could get over Plum Creek and approach the bird
for a better look and photos.
We were able to see both the top and bottom of the bird and watched it
for several minutes before it landed. The bird looked quite dark when
standing on the shoreline (approx. 150-200 yards away).
The bird appeared dark brown. The central tail feathers barely extended
beyond the others. The bird's bill was massive, relative to its head.
The upper and lower wings looked quite dark. We did not see lighter
tips on the outer primaries (which looked similar in color to the wing).
I remarked to Paul that the broad wings and heavy body appeared to be
that of a Pomarine Jaeger. It seemed to me that the proportions seemed
balanced for a Pomarine. A Long-tailed Jaeger would have a smaller body
and the thin wings would have looked much longer. A Parasitic Jaeger
would have a slightly bigger body and wings, however a small bill.
We decided to report the bird to CoBus, however not the general public.
The hope was the bird would return and other birders confirm our ID.
Return to Bluff Lake Nature Area 9/20
Bryan Ehlmann and I spent an hour at Bluff Lake Nature Area (Denver County)
early this morning. We found two Townsend's Warblers and did not find the
Northern Parulas or Waterthrush observed Monday by Loch Kilpatrick and myself.
We continued on to Wheat Ridge Greenbelt (Jefferson County). Again the
only bird of interest was a Townsend's Warbler. Birding was slow here.
A quick stop at Standley Lake (Jefferson) added a Sabine's Gull to our day
list. We did not have a scope with us and did not find the Common Terns.
We stopped at only two of the Prairie Dog Villages along my favorite Owl Loop
(Adams County). Five Burrowing Owls were at Powhaton & 128th avenue
and two birds were at 3.4 miles east of Tower Road & 96th avenue.
Bluff Lake, Denver 9/17
I spent 2 hours at Bluff Lake in the early afternoon. I had to wait for
the rain to stop. Temperatures were in the low 70s; skies were cloudy.
A Northern Waterthrush walked the shoreline approximately 80 yards south
of the northwest bird blind. The shoreline cannot be seen from the blind.
An interesting flock of birds was on the north side where the path goes
under the willows. The flock included two Northern Parulas, two Townsend's
Warblers, four Wilson's Warblers, and several Yellow Warblers.
At the same time I was observing the two Parulas, Loch Kilpatrick was watching
a third Northern Parula in the tall cottonwoods 500 yards east of my location.
In the distance we could hear Greater and Lesser Yellowlegs.
Two Great Blue Herons, an immature Black-crowned Night-Heron,
and a dark-morph Red-tailed Hawk flew overhead during my stay.
The cottonwoods 50 yards north of the marsh along the path had
a nice flock of warblers also. There were Wilson's Warblers,
an adult Townsend's Warbler, and a Ruby-crowned Kinglet.
Cherry Creek Reservoir 9/15
A short trip to Cherry Creek Reservoir this morning was not eventful.
There were only Ring-billed, California, and one second year
Herring Gull at the southwest marina.
It took 30 minutes to find the Green Heron at the wetlands pond
east of the Prairie Loop. The bird was at the eastern end of
the canal between the two islands.
From the handicapped fisherperson's dock, I could see
five Black Terns and two Forster's Terns out about 50 yards.
No warblers could be found in a two-hour search.
Barr Lake Area 9/14
We visited the Barr Lake area again this morning.
(Another beautiful day, no wind and temperatures in the lower 80s).
It was a pretty slow day compared to last week.
We did not locate the Sabine's Gulls reported earlier in the week.
A Townsend's Warbler was at mile marker 8.2.
A young American Redstart fluttered about at mm 8.3.
One Plumbeous Vireo was in the cottonwoods at mm 8.4.
We hit my favorite Owl Loop on the trip back to Denver.
Burrowing Owls were found at:
7 at Powhaton & 128th avenue
3 at 3.4 miles east of Tower & 96th avenue
5 at 1.0 miles south of Buckley & 88th avenue
Wheat Ridge Greenbelt 9/13
What a beautiful morning! There was no wind during our five-hour stay.
Temperatures stayed in the seventies; clouds did not roll in until we left.
The woods were silent except for a few birdcalls and the distance traffic.
We could hear well; unfortunately the woods were not very birdy today.
We hiked from Kipling to Youngfield and back. A lone adult Black-crowned
Night-Heron hunted along Clear Creek approximately 0.4 mile from Kipling.
Two Barn Swallows and one Cliff Swallow flew over the Night-Heron.
A single 1st year Western Tanager called near the Girl Scout Corral.
Nothing answered him!
Maybe the Sharp-shinned Hawk that flew by had something to do with that!
A male Northern Cardinal called and made a brief appearance just west of
the pond at the northeast corner of the chain link fence.
Two Wilson's Warblers called and a female/immature Townsend's Warbler
were in the cottonwoods just south of Prospect Bridge & the fence.
A fourth bird remained unidentified. It appeared to be a vireo, had
yellow on the breast, and white undertail coverts. We never saw the
bird from above and its wings and back remained a mystery.
Two male Downy Woodpeckers fluttered about at the west end of the
chain link fence. Several Northern Flickers called here also.
A flock of 6 Wilson's Warblers, 1 Orange-crowned Warbler, and a second
Townsend's Warbler was in the cottonwoods north of the tree bridge.
(Trail leading west from the south side of Prospect Bridge over Clear Creek).
The woods south of the tree bridge were completely silent.
Two Wilson's Warblers were in the Russian Olive Trees at the northeast
corner of Bass Lake. Except for American Goldfinches, House Finches,
European Starlings, American Crows and 6 White-breasted Nuthatches,
that was our list of birds for the day.
Chatfield Reservoir 9/11
First light found me at Chatfield Reservoir. There was zero wind until 1:00PM.
Temperatures stayed in the 70s until after 2:00PM. What a beautiful day.
(Until I heard in the late afternoon about tragedies back east).
I spend three hours birding the Kingfisher Bridge area to about 1.5 miles south.
Two flocks of Wilson's Warblers totally 10 birds contained one immature American
Redstart and 2 male Yellow Warblers. I came upon 9 Catbirds, 3 House Wrens,
one American Robin, 3 Cedar Waxwings, and 2 Red-breasted Nuthatches.
Two immature male Broad-tailed Hummers put on quite a show chasing each
other the whole time I was in the area! There were a total of 7 BTHU observed.
No flycatchers could be found!
Next I walked the shoreline between the two Heron Rookeries. One Black-bellied
Plover was preening himself about halfway between the two heronries.
At the Plum Creek Delta area (southeast corner of the reservoir) many birds
were along the shoreline. One Caspian Tern stood among 20 Ring-billed and
7 California Gulls. One juvenile Sabine's Gull flew overhead.
Two Clark's Grebes were "accompanied" by 8 Western Grebes. A lone
Osprey stood on one of the tree stumps sticking out of the mud.
The numerous sandpipers feeding along the shoreline included
one Pectoral, 31 Baird's, 2 Least, and 8 Killdeer.
Seven Great Blue Herons fed in the area also.
The swim beach area on the western side of the reservoir added
17 Ring-billed and 9 California Gulls to my day list.
Wheat Ridge Greenbelt and Barr Lake 9/7
Bryan Ehlmann and I drove over to Wheat Ridge Greenbelt (Jefferson County)
this morning. Temperatures were cool; winds were calm.
Bryan found a Cassin's Vireo crossing (and moving west) at the path
that goes uphill to the subdivision to the south of the tree bridge.
One Townsend's Warbler was south of the chain link fence just south
of the Prospect Footbridge. No other warblers could be found.
A Plumbeous Vireo was in the trees just south and west of the
eastern bridge (off the Kipling Avenue entrance to WBG).
Bryan Ehlmann, Rebecca Kosten, and I went to Barr Lake (Adams County)
Friday afternoon. Temperatures were in the 70s; winds were mild.
We did not locate any of the uncommon warblers found earlier in the week.
Two American Redstarts were at mile marker 8.4. Townsend's Warblers
were at: 1 at mm 8.6, 2 at mm 8.4, and 2 at mm 8.2.
Two unidentified "Empidonax" species, one Western Flycatcher,
two Red-breasted Nuthatches, four Western Kingbirds, nine
House Wrens were also found. One immature Bullock's Oriole
was just west of the dam at mile marker 7.3.
We drove my favorite owl loop on the trip back to Denver.
Burrowing Owls were found at:
(3 birds at 1.0 miles South of Buckley Road & 88th Avenue)
(7 birds at 128th avenue & Powhaton Rd
(2 birds at 3.4 miles East of Tower Road & 96th Avenue)
Along the eastern side of the Rocky Mountain Arsenal we also
observed 3 Western Kingbirds, 5 Lark Buntings, Chipping Sparrows,
Lark Sparrows, Vesper Sparrows, and one Swainson's Hawk.
Return to Barr Lake 9/3
Paul Langendorfer and I traveled to Barr Lake this morning.
At 6:15am, we were the first of 40 or so birders who searched this morning.
The Nashville Warbler was under the large cottonwood tree at mile marker 8.6;
it later flew to the weeds on the south side of the canal.
The large cottonwood also contained 9 Townsend's Warblers.
The Canada Warbler and Golden-winged Warbler popped up
briefly from the weeds south of the canal.
The Townsend's Warblers ended up there also.
Among flocks of Wilson's Warblers two Townsend's Warblers
each appeared at mm 8.5, 8.2, and 7.6. Two immature
American Redstarts flew about just east of the banding station.
A Great Horned Owl hunted at mm 7.3
curve just before trail drops below the dam).
Linda Andes and her group found a Rock Wren around
the dead limbs at mm 8.3. Thanks for the heads up!
Paul and I traveled to below the dam and added
no further uncommon birds to our day list.
On the trip back to Denver, we drove my favorite Owl Loop
and found Burrowing Owls:
9 at Powhaton & 128th avenue
2 at 3.4 miles east of Tower & 96th avenue
5 at 1.0 miles south of Buckley & 88th avenue
Clear Creek County 9/2
Kevin & Betty Meston of Maryland and I traveled to Guanella Pass.
Skies were partly cloudy; winds were strong.
We managed to find two White-tailed Ptarmigan in the first 30 minutes
of our hike. The birds were 200 yards south of the junction of the
Rosalie and 603 trails (and 60 yards east of Rosalie Trail).
We searched for another hour and found no additional birds.
On the trip up we stopped briefly at the Guanella Pass Campground.
We found a male Three-toed Woodpecker in the first 20 minutes.
Luck was with us today! The TTWO was 60 yards southeast of the
entrance to the campground. A male MacGillivray's and two Wilson's
Warblers were along the stream that leads west.
Our next stop was Georgia Pass. We found two male and three female
Pine Grosbeaks on the drive to the summit. The birds were 0.2 miles
from the top. They fluttered back and forth across the road.
Six Gray Jays and two Clark's Nutcrackers were feeding at the top.
We stopped last at Pike National Forest east of Bailey. No TTWOs
were located in our two-hour hike along the Skipper Trail. A male
Williamson's Sapsucker was just north of the Buck Creek bridge.
Several Townsend's Solitaires and two Western Bluebirds were
encountered along the hike. Chipping Sparrows seemed to be everywhere.
Barr Lake 9/1
Since I dropped off friends at DIA this morning and had to pickup
another friend later in the day, I birded 6.5 hours at Barr Lake.
There was no wind until 2:00pm. Temperatures rose throughout the day.
On the trip to Barr Lake, I drove my favorite owl loop.
Burrowing Owls were observed at:
9 birds at Powhaton Road & 128th avenue
6 birds at 3.4 miles East of Tower Road & 120th avenue
2 birds at 1.1 miles South of Buckley Road & 88th avenue
Along the east side of Rocky Mountain Arsenal (4.0 miles),
there were 43 Western Kingbirds, 31 Lark Buntings, 100s of
Vesper Sparrows, 2 Grasshopper Sparrows, many Chipping
Sparrows, one Eastern Kingbird, and one Red-tailed Hawk.
My 6.5 hours at Barr Lake produced some interesting sightings.
An Olive-sided Flycatcher was singing at mm 8.4.
Just west of here, two Townsend's Warblers were fluttering about.
At mile marker 8.2 there was a flock of birds, which included
14 Wilson's Warblers, 7-9 Townsend's Warblers, 4 Yellow
Warblers, accompanied by 18 Black-capped Chickadees.
Continuing east, at mm 7.6 (boat ramp), two additional Townsend's
Warblers were in a flock of 5 Wilson's and 2 Yellow Warblers.
A final pair of Townsend's Warblers was at mm 7.3 (just before
the road curves north down below the dam.
Two lone Barn Swallows hawked insects at mile marker 7.2
I circled the trees west of the Bird Observatory and found one
immature American Redstart at the south end of the grove.
There were several flocks of Wilson's and Yellow Warblers in the
trees along the outlet canal below the dam.
Construction trucks below the dam kicked up 27 Black-crowned Night-Herons
and 19 Great Blue Herons. Four Franklin's Gulls flew overhead also.
My next stop was the trees north of the banding station. One flock
of birds included the female Canada Warbler and a Blackpoll Warbler.
Two Townsend's Warblers were here also, however I did not count
them as additional birds for the day (they could have come from
flock observed earlier in the day.
One Snowy Egret was feeding in the shallows at mm 8.0.
After picking up Bryan Ehlmann at DIA, we headed for Cherry Creek Res.
We did not locate the Green Herons at the wetlands pond east of the
Prairie Loop. There were 6 Black-crowned Night-Herons and 5 Great
Blue Herons however (and many mosquitoes).
