[cobirds] Bobolink, El Paso County

Late this afternoon, I saw a Bobolink at the western end of Tamlin Road, El Paso County, a short distance  before the pavement ends.
I saw it briefly in the grass by the fence then watched it fly  to the south.
It seems a bit early for this bird?
 
At the Squirrel Creek pond, there were 7 Least Sandpipers, 2 Avocets, about 120 Ibis, 3 Wilson's Phalaropes and a few ducks. The water level is low. 
There was a lone Canada Goose calling a lot; I wonder if it's the same one who lost his/her mate there last year; they were nesting and one morning I saw a Peregrine Falcon eating one of the Canada Goose right by the nest. I presumed he/she had killed the goose on the nest.

[cobirds] Boulder County, April 30th

Hello, Birders.

During the lunch hour today, Monday, April 30th, Andrew and I visited south Teller Farms (access from Arapahoe Road), and we saw an Upland Sandpiper--presumably the same bird I observed there yesterday. Today we saw it only in flight--flying north as if toward Teller Lake No. 5. Also present was a singing FOY Lark Sparrow.

A few other Boulder County sightings from earlier today for Andrew and me: Teller Lake No. 5 had a Baird's Sandpiper and a Great Egret; Coalton Open Space (east entrance, off McCaslin Road) had a Loggerhead Shrike and 3 FOS Western Kingbirds; and Prince Lake No. 2 had 4 Long-billed Dowitchers.

I note, by the way, that Greenlee "Reservoir" has great shorebird habitat, but not a lot of shorebirds, right now. This evening, Hannah and Andrew and I saw only a Spotted Sandpiper, a few Killdeer, and a flock (well, n=3) of Solitary Sanpipers. Also a White-faced Ibis, an indeterminate Plegadis sp., many Yellow-headed Blackbirds, and 2 or 3 Great-tailed Grackles.

One final comment. Ten years ago today, I moved to Colorado. Thanks to all of you for a warm welcome this first decade!

[cobirds] Poorwill, Plumbeous Vireo, Warbling Vireo, Virginia's Warbler found on Phantom Canyon Rd in Fremont County

During an overnight camping trip to Phantom Canyon Sunday night, 4/28-29, we
found several singing Virginia's Warblers, at least two singing Warbling
Vireos, a Plumbeous Vireo singing and acting like he was on territory,
Bushtits, and after dark we heard a Common Poorwill. Specifically, we were
camping at the ghost town site McCourt at ~6500' along SH 67 (the Phantom
Canyon Rd) in Fremont County.
Good birding to you.

[cobirds] Fremont Cty - White-eyed Vireo, Yes - Field Sparrow, No

First of all, thanks a lot to Brandon Percival for his report on the White-eyed Vireo on the Canon City Riverwalk.

 

Jeanne and I had already planned to go to Canon City today, but because of Brandon's post we listened to several recordings of the vireo and the field sparrow. We never did see or hear the sparrow, but within a half-hour of parking by the Sells Pond, we clearly heard the  vireo in some thick bushes right off the riverwalk path. We only got a brief glimpse of the bird, but it was enough to make a positive ID along with the song.

 

Other Fremont County highlights:

 

Canon City: Yellow warblers, 4 swallow species

 

Holcim Wetlands: Ladderback Woodpecker, Common Yellowthroat

 

Brush Hollow: Common Loon (basic plumage), Cassin's Kingbirds, Western Kingbirds

 

Good birding, everyone!

[cobirds] Cliff swallows have returned to Peyton, possibly a Cooper's Hawk

This year, over the past 2-3 weeks we have had an infestation of miller moths. My garage was full of these pesky things the past few weeks. I wished for a good solution and it happened.

 

Last year, we had 3 cliff swallow nests attached to our roof peaks. At any given time, you could step outside and see 40-60 cliff swallows swopping around within 10-20 seconds. Well, mysteriously, I noticed a sudden lack of miller moths the other day and no bodies in the garage. I had seen some swallows swooping around, and about the time the millers disappeared, I noticed a new mud nest under full construction.

 

Seems the cliff swallows from last year return to re-build their nest(s) and gorge themselves on a high-protein diet of miller moths, or at least the ones my terriers didn’t get (inside the house the moths don’t stand a chance.) I welcome these swallows: they can build their nests as long as they offer insect control.

 

As I was writing this, possibly a Cooper’s Hawk nailed a rabbit not 10 feet from my window. He was fairly large (at first I thought it was a golden eagle but later realized it wasn’t) and had real yellow legs and long black talons. He pounced on a young rabbit a few times, and after 5 minutes took-off with dinner in-tow; one less rabbit for my terriers to chase. It kind of took me by surprise as it happened so quickly, close and silently. As it flew off it had a fairly good wingspan (3-4’ ft?) and wasted little time getting airborne. I know we have hawks out, just not sure about what kind.

Official CounterJoyce Commercon
Observers: Cynthia Madsen, Dave Hill, Francis Commercon, Heidi Seeland, Jeff Birek, Robert Hill, Tim Smart



Visitors:
A Denver Field Ornithologist (DFO) field trip, led by Tim Smart, got started early on the Ridge, and included Jayne and George James as well as Robert Hill. A little later in the morning, an Audubon Society of Greater Denver (ASGD) field trip of fifteen, led by Dave Hill and Cynthia Madsen, arrived to learn about hawk identification and HawkWatch from RMBO biologist Jeff Birek. As usual, a number of hikers stopped by for the view; some of them curious about hawk-watching.

Weather:
The day was sunny and partly cloudy with minimal cloud cover (hugging the North and West horizons) early on, increasing to about 50 percent coverage scattered over the sky later in the day. Cool, level 2 B winds came from the East and Northeast. The temperature rose from 12 C to 15 C. There was reasonably good visibility but with noticeable haze to the South and Southeast.

Raptor Observations:
The best bird of the day was the adult Broad-winged Hawk that migrated directly over the Ridge mid-morning. A local Swainson's Hawk passed (going South) close by the Broad-wing, which made for a nice comparison of species. One of the local nesting Peregrines aggressively drove one and then another of two migrating Peregrines out of its territory early in the morning. There was a lot of local Cooper's Hawk activity, including some territorial flight displays, which were pointed out by Jeff Birek. Some local Turkey Vultures spent the day passing back and forth North and South from behind Mt. Morrison to Cabrini.

Non-raptor Observations:
Four American White Pelicans were spotted well South of the Ridge headed further South. Eight Common Ravens spiraled up over WestRidge and went South over Mt. Morrison. A group of about five Violet-green Swallows flitted about near the Ridge late in the afternoon. Other birds seen or heard included Blue-gray Gnatcatcher, Mourning Dove, Black-billed Magpie, Spotted Towhee, White-throated Swift, Bushtit, Yellow-Rumped Warbler, Broad-tailed Hummingbird, Western Scrub-Jay, Barn Swallow, and American Robin.


Report submitted by Rocky Mountain Bird Observatory (jeff.birek@rmbo.org)
Dinosaur Ridge information may be found at: http://www.rmbo.org/

Site Description
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is the
best place in the world to see migrating Ferruginous Hawks. Dinosaur Ridge may
be the best place in the country to see the rare dark morph of the Broad-winged
Hawk (a few are seen each spring). Hawkwatchers who linger long enough may see
resident Golden Eagles, Red-tailed Hawks and Prairie Falcons, in addition to
migrating Swainson's, Cooper's and Sharp-shinned Hawks, American Kestrels and
Turkey Vultures. Peregrine Falcons and Ferruginous Hawks are uncommon; Northern
Goshawk is rare but regular. Non-raptor species include Rock Wren, and sometimes
Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift, American White
Pelican or Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from the Rocky Mountain Bird
Observatory from about 9 AM to around 4 PM from the first week of March to the
first week of May.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take left
into first parking lot, the Stegosaurus lot. Follow small signs from the south
side of lot to hawkwatch site. The hike starts heading east on an old two-track
and quickly turns south onto a trail on the west side of the ridge. When the
trail nears the top of the ridge, turn left, head through the gate, and walk to
the clearly-visible, flat area at the crest of the ridge.

[cobirds] San Luis Lake, Alamosa County

We "discovered" lake San Luis (had never been there before) on the way to the  Sand Dunes yesterday, after unsuccessfully searching for the Red Knot at Homelake (Rio Grande County); of note however was one Clark's Grebe with the Western Grebes.
   
San Luis Lake, Alamosa county:
 
125-150 Marbled Godwits
20+ Willets
18-20 Long-billed Dowitchers
500+ Wilson's Phalaropes
50+ Avocets
A single Greater Yellowlegs 
One unidentified Peep (too far)
 
I don't know what the normal water level is at this lake but judging from the large amount of dried up shore and the water not reaching  boat launches, it seemed very low. 
Having grown up near water with huge tide levels, my first thought was: low tide, good for shore birds; DUH!!!

[cobirds] Lamar (Prowers) visit (4/23-29) summary

Report from Lamar (Prowers) for April 23-29:
 
The tornados were exciting, or so they say.  I slept right thru it all, including the town siren, 585 lightning strikes in one 15-minute stretch (according to one of the Denver news reports), and fierce winds/rain.  They say tornados went both east and west of town, but luckily spared almost everything (except about 100 power poles) and everybody.  Electricity was out in Lamar from about 1:30am to 6pm on the 28th.  I woke up that morning dreaming of Painted Buntings, Swainson's Warblers, and Whip-poor-wills sitting around in the streets.  But the only species that seemed to have fallen out of the storm clouds was Say's Phoebe (at least 12 seen, with zero observed in the 5 days prior).
 
At any rate, I ended up with 98 species for the Lamar area, which compares with 135 during roughly this same week in 2010.  In general, I would say things were very slow (LCC especially so), but beginning to pick up.  No vireos, no orioles, very few warblers, very few thrushes, only 2 buntings, only 3 Ruby-crowned Kinglets (together at one place for a few days, no others), only 1 gnatcatcher, 1 grosbeak, no Broad-winged Hawks, no empids, good numbers of sparrows (including so many Gambel's white-crowns I found myself wishing for anything else, even one with a black lore).  The habitat looks great.  The insects are out (including zillions of Army Cutworm moths (aka "millers")).  If the birds arrive, they will have all the necessary accessories for migratory travel.
 
Best birds this week were in Jane Stulp's yard, which can be sleuthed on eBird.  Of course, this major farm operation is private, prior permission is requested, and Jane is most gracious when home and agribusiness allows visitors.
 
Outside the Stulp yard I had:
Rose-breasted Grosbeak (1 young male at Fairmount Cemetery (FC) on both 4/23 and 4/24)
 
Northern Parula (1 non-singing adult female at FC on 4/28, mostly in the elms among the north-south pine row east and uphill from the entry)
 
Upland Sandpiper (1 flew over the Lamar High School football fields, called as if to land, and kept on going on 4/28)
 
Long-eared Owl (1 hanging out at the south end of the Lamar High School windbreak on 4/27 and 4/28)
 
Barn Owl (in a private barn north of town, in a nest box)
 
Northern Cardinal (at least 3 singing males in the woods east of Lamar Community College, presumably females are on nests)
 
Red-bellied Woodpecker (at least 2, maybe as many as 4, at various places including LCC, Willow Creek Park, and FC)
 
Field Sparrow (1 in the LHS windbreak on 4/27, 1 singing in a private yard east of Wiley on 4/28).  The one at LHS was a "western".
 
Cassin's Sparrows back in appropriate sand sage and other scrub-prairie habitats
 
White-winged Dove (as many as 3 in a private yard in Willow Valley subdivision east of Willow Creek Park, also seen and heard other places including Riverside Cemetery on Maple Street a mile or so east of Main)
 
Olive-sided Flycatcher (1 imm. at Tempel's Grove on 4/28 (Bent CR35 about 3.2 miles north of CR SS, stay on the ditch road, park on the west side but don't block access to gas pump or hay piles))
 
Eastern Phoebe (Tempel's Grove 4/22 to 4/27 but may have left when the water level in the canal dropped to zero)
 
The dove population in Lamar is truly phenomenal.  I have heard many birders say/speculate collared-doves are hurting Mourning Doves.  That does NOT seem to be the case in Lamar.  Of note, but not necessarily related, the local Inca Dove population present a few years ago seems to have disappeared.
 
Nothing unusual at Last Chance today on the way home.
 
I have never seen so many Red Admiral butterflies (larval food plant being nettles) as have been active all along the eastern plains in the last week.

Hawk (a few are seen each spring). Hawkwatchers who linger long enough may see
resident Golden Eagles, Red-tailed Hawks and Prairie Falcons, in addition to
migrating Swainson's, Cooper's and Sharp-shinned Hawks, American Kestrels and
Turkey Vultures. Peregrine Falcons and Ferruginous Hawks are uncommon; Northern
Goshawk is rare but regular. Non-raptor species include Rock Wren, and sometimes
Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift, American White
Pelican or Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from the Rocky Mountain Bird
Observatory from about 9 AM to around 4 PM from the first week of March to the
first week of May.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take left
into first parking lot, the Stegosaurus lot. Follow small signs from the south
side of lot to hawkwatch site. The hike starts heading east on an old two-track
and quickly turns south onto a trail on the west side of the ridge. When the
trail nears the top of the ridge, turn left, head through the gate, and walk to
the clearly-visible, flat area at the crest of the ridge.

[cobirds] White Ibis flyover, Adams County

At around 5:30pm, while I was in a parking lot @ 35th & Tower (leaving a store), I saw two Mallard sized birds in the distance, about to fly over my car.  The flight pattern didn't look right for Mallard, so I sat in one spot without driving off, waiting for them to fly over.  They came in from the west and were backlit, but as they got near, I recognized them as ibis with the shape of their bodies and faces.  Expecting White-faced Ibis,  I kept my eye on them and nearly jumped outta my chair when they flew directly overhead, fairly low and I saw bright white plumage with black in the wingtips.  They were headed Northeast, but more east than north.  I looked up some reports on eBird and found they were seen at Barr Lake and Julesberg reservoir in the past - which would make sense considering the direction I saw them flying.  Hopefully someone will be able to re-find these two beautiful birds during the next few days !

[cobirds] Boulder County, April 29th

Hello, Birders.

Some odds and ends from around Boulder County earlier today, Sunday, April 29th:

At Boulder Reservoir, in the 2pm hour, Bill Schmoker and Hannah and I re-found the female LONG-TAILED DUCK discovered earlier in the day by Christian Nunes. Nice bird for Boulder County, especially so in late April. Also present at Boulder Rez were two distant, vexing Calidris sandpipers. Too far away to be sure, but I thought they had a decent chance of being Sanderlings in prealternate molt; on the other hand, they seemed too small; on the other other hand, they WERE far away...

Butterflies, too, at Boulder Rez. For the hour-plus we were there, we observed a constant passage of painted ladies migrating west-northwest across the lake.

Earlier in the morning, in the southern stretches of the Teller Farms region, I found an UPLAND SANDPIPER in the low grass just a bit west of Teller Lake proper. (Not Teller Lake No. 5, i.e., the more famous of the Teller lakes.) Coordinates were 40.022686 N, 105.155159 W, but I'm not hugely hopeful for a repeat performance, as I went on to hear the bird give several flight calls, suggesting it was flying away. Random thought: Look for Upland Sandpipers in Boulder County this spring and summer!--Think back to all the "Midwestern" goodies in the county last summer: Red-headed Woodpeckers, Eastern Phoebes, Cassin's Sparrows, Eastern Warbling-Vireos, Dickcissels, and more.

Earlier still, along the Fowler Trail, near El Dorado Springs, Bob Zilly and I enjoyed a dawn chorus of numerous COMMON POORWILLS, a few WILD TURKEYS, and SPOTTED TOWHEES. At sunrise we found two BLUE-GRAY GNATCATCHERS, a male and female, seemingly already paired.

One last observation from this morning: Numerous singing SAVANNAH SPARROWS for Bob and me at the City of Boulder Open Space headquarters off Cherryvale Road.

[cobirds] White-Winged Dove, Fremont County

Checking along Route 120 near Portland, I found a White-Winged Dove just past the second bridge from the east end (~1.8 miles in).  Not much else of interest other than a pair of very friendly Say's Phoebes.  Holcim wetlands were generally quiet, aside from the activity around the GBH and DCC nests.  There was a nice fly over of 9 White-faced Ibis and a Wilson's Snipe ran into the vegetation along the creek east of the wetlands.

[cobirds] Weld Wanderings

Hi,

Jeff and I headed up to do a relaxed day of birding in Weld County.

Our first stop was Crow Valley Campground where we found Steve
Mlodinow and Nick Moore already present.

The campground was quite birdy, mostly Spotted Towhees and a solid mix
of sparrows (White-crowned, Brewer's, Clay-colored, Chipping,
Lincoln's, Vesper), but with a few other treats. Jeff and I were able
to see the Palm Warbler found by Steve and Nick as well as at least
one Wilson's Warbler. To round-out the warblers, we had
Orange-crowned (couple) and Yellow-rumpeds (mostly Myrtle). We also
found a Hermit Thrush as well as Nick and Steve's Long-eared Owl doing
an outstanding branch imitation.

Jeff and I then drove WCR 96 (the birding route) and had surprisingly
little. We found no longspurs and no plovers. Lots of Vesper
Sparrows and Horned Larks. One possible female Lark Bunting was
observed through the curve of the windshield.

We wrapped up the afternoon doing some water-birding with some nice results.

The farm pond north of Galeton on WCR 51 held 5 Marbled Godwits.

More Marbled Godwits (roughly a dozen) along along with lots of
Wilson's Phalarope, Long-billed Dowitchers, and a couple possible
Short-billed Dowitchers were present on WCR 59 just south of the Kuner
Feedlots (US 34).

Loloff held six Whimbrel on the west side near the oil tanks as well
as a Willet and more distant dowitchers.

Beebe Draw at WCR 42 was sporting yet another Marbled Godwit as well
as two Long-billed Curlew.

American Avocet and Black-necked Stilt and ducks of all types were
also seen in many locations.

A great day to be out with some fun birds.

Good birding,

Kathy Mihm Dunning
Denver

[cobirds] White-eyed Vireo & Field Sparrow (Fremont County) 4/29

Hi all,

Six birders (4 from Colorado Springs and 2 from Pueblo) walked along the Canon City Riverwalk in Canon City this morning, during an Arkansas Valley Audubon field trip.  We walked from Raynolds Ave. west to Sell Ave. and back, our highlights were a singing FIELD SPARROW and a singing WHITE-EYED VIREO.  Both of these are quite rare in Fremont County.  They were in-between Raynolds Ave. and Sells Ave., the sparrow was between the bluff trail and the river trail, and the vireos was along the bluff, south of the Bluff Trail.  Other things this morning were Yellow-breasted Chats, Bullock's Orioles. pair of Western Bluebirds, Yellow Warblers, quite a few Yellow-rumped Warblers near Sells Ave. parking of the Riverwalk.  After the riverwalk, we walked around Pathfinder Regional Park, the White-throated Swifts put on a nice show there.  After lunch, we checked Holcim Wetlands, near Portland, nothing too exciting, though always nice to see the nesting cormorants and Great Blue Herons.
 
Good birding

[cobirds] Boulder Co. Long-tailed Duck, Glossy Ibis 4/29/12

Hello birders,

At about 6 am, there was a breeding-plumaged female LONG-TAILED DUCK with a group of REDHEADS and 1 LESSER SCAUP in the northwest corner of Boulder Reservoir. No large shorebirds at the NW corner, but there were 2 SEMIPALMATED PLOVERS and 7 WILSON'S PHALAROPES. 

Over at Cottonwood Marsh, there was 1 WILLET and a SOLITARY SANDPIPER. A flock of ibis flew in, and one was a GLOSSY. The other 7 where WHITE-FACED. 

Good birding,

[cobirds] RMBO CBR Banding Saturday

Hi COBirders,

Report for RMBO banding at Chico Basin Ranch for Friday (4/27) and Saturday (4/28) (El Paso County, fee area)

Most days this week we got the distinct impression (again) that this is early in migration. Slow starts, sometimes no birds until about 10 am, then some small flocks moving up into the grove as it gets warmer. Just not many flocks the past few days.

Friday, 9 new birds banded
Blue Jay 2
Brown Thrasher 1
Orange-crowned Warbler 1
Audubon's Yellow-rumped Warbler 1
Spotted Towhee 3
Chipping Sparrow 1

and not much else seen in the grove, either.

Saturday 23 new birds banded
Warbling Vireo 1
Blue Jay 2
Hermit Thrush 4
Am Robin 1
Brown Thrasher 2
Orange-crowned Warbler 1
Myrtle Yellow-rumped Warbler 4
Audubon's Yellow-rumped Warbler 4
Spotted Towhee 2
Chipping Sparrow 2

The Ladder-backed Woodpeckers persist - possibly nesting, Long-eared Owl (one) has been seen early, but mostly leaves grove as we start moving around. Western Kingbirds have been seen and heard since Thursday, and a lone Lark Bunting male was seen yesterday. Many Blue Jays around, some with brood patches developing.

Banding resumes Monday, through Saturday.

See you soon,
Steve Brown (chief grunt)

[cobirds] Boulder Res - Long-billed curlew

Started a 42 mile birding ride at Boulder Res where we spotted a Long
billed Curlew, Marbled Godwit, two Willets and an Am Avocet.
Continued to Lagerman res, which was quiet for shorebirds, but the
osprey nest is occupied. Not much at Clover Basin either. The Owl
nest in the rookery near Crane Hollow road continues. Did not see
the Stilt at Golden ponds,but we did have some nice looks at Cinnamon
and Blue-winged teal.

[cobirds] CHAT Banding Station Report 4/28/12

A typical opening day at the Chatfield Banding Station – few birds but lots of cheerful visitors, happy to be out enjoying a beautiful spring day.  Banded six birds – 1 Hermit Thrush and 2 Spotted Towhees (arriving right on schedule) and 1 Common Yellowthroat (a full week earlier than its normal first capture at CHAT).  1 Black-capped Chickadee and a Robin.  House Wrens are back and making lots of noise, but they stayed up high today.

 

Open daily (except for May 18-19), weather permitting, through June 3!

[cobirds] Prospect Park, Jefferson County, 04/28/12

Hi all,

I led a DFO trip this morning to Prospect Park in Wheatridge, Jefferson County. It was a beautiful morning, despite the temps being on the cool side. Passerine migrants were pretty much non-existent besides Yellow-rumps, but we made up for it with an eclectic mix of good sightings. Highlights are

Virginia Rail with babies - on the south side of West Lake there is a boardwalk, from there we first saw an adult, then three of us had three separate sightings of what would have to be at least one, probably two, hatchlings. Is it way too early?
Broad-winged Hawk - one flying low over us and kept going north, giving us good looks but we can use a longer one
American Bittern - pretty much the first bird of the official trip, landed on a tree to give everyone a good scope view
Plegadis ibis - 3 of them, presumably white-faced, never did land for a look
Peregrine Falcon - a quick flyby

[cobirds] 1st year(?) White-crowned Sparrow, Louisville, Boulder County

For the last several days, I have had a White-crowned Sparrow singing softly almost all day long from within my spruce trees in front.  I have a small yard, but they come by every year in migration.  This year, the bird sounds quite tentative, as if practicing its song for the first time.

[cobirds] Broad-winged Hawks, Larimer

Hi everyone,

I led a beginner bird group this morning in Fort Collins, generally along the Poudre River Trail just west of Riverbend Ponds Natural Area. Very little in the way of migrant songbirds (or almost any songbird, for that matter) this morning - the strong winds overnight seemed to suppress activity, sad to say. Still, I kept the group entertained somehow.

One thing that helped was finding a pair of Broad-winged Hawks circling overhead and drifting northward along the Poudre drainage around 9am or so.

We also liked finding a baby (?) snapping turtle along one of the trails at the natural area. It was surprising seeing what looked like a recent hatchling, even though it's only late April.

Good birding,
Eric

[cobirds] Eastern Phoebe Boulder County

Cobirds:
Stopped at Twin Lakes this morning. Found an eastern
phoebe calling and foraging along the irrigation ditch. From
Gunbarrel go to 63rd, turn on Natuilus Drive east, and go to Eaton
Park (left). Walk along the irrigation ditch on the lake side (the
lake with water in it). I saw and heard the bird along there.

The Twin Lakes great horned owls have two visible chicks (3/4 grown)
in the hollow snag along the hiking trial, just like last year.

[cobirds] Night birding Pueblo County late 4/27 & early 4/28

Gene Rutherford and I did some night time birding late yesterday and early this morning.

Up in the Wet Mountains, near Beulah, we heard 6 Flammulated Owls, 6 Common Poorwills, 1 or 2 Long-eared Owls.  These were heard on 4/27 (after 10pm).  We didn't hear or see any Northern Saw-whet Owls, which seemed surprising.

Then we checked marshy areas in the eastern part of Pueblo County, and had two or three calling Black Rails, a Sora, a Virginia Rail, a singing Marsh Wren (not a usual breeding bird in Pueblo County), and several Great Horned Owls (these were before 3am).
