[cobirds] Hepatic Tanager also in Lamar Woods this morning

I was again surprised today to find a Hepatic Tanager this morning in Lamar Woods, surely the one reported by Scott Severs from this afternoon.   Winds this morning, while not as awful as yesterday, were still very strong and this tanager stayed mostly in thickets.   I got one good photo of this surprise visitor that I have uploaded to my Birds and Nature blog

[cobirds] Marston Reservoir, Denver

Some shorebirds are still at the south end of Marston Reservoir. I saw  6, Marbled Godwits, 2, American Avocet, 1, Willet and 5, Franklin's Gull in the south  area. Several days ago  there were at least 190-200 Franklin's Gulls at Marston, but their numbers disappeared quickly. Western Grebes remain at the lake along with the common Dabbling Ducks. Say's Phoebe are in various different territories around the Lake Marston.
 
Happy Birding!

[cobirds] Re: Colorado Springs Recent Sightings 4/28-30 (El Paso)

Forgot also to add an American Dipper in Manitou Springs yesterday (4/29), at the north end of downtown along Fountain Creek. This seemed especially strange as they are digging out sediment in the creekbed, so there was heavy machinery within 20 ft. up- and downstream and the water was murky as can be.

Hi All,

This is primarily I would think of local interest. No rarities to speak of, but there have been many birds around the Springs recently worth mentioning.

Monday (4/28) there were two Hermit Thrushes at the Colorado College Farm. I found several Cooper's Hawks: a nesting pair on CC campus, an adult male with a kill in Shooks Run Park, and two (one with a kill) in Williams Canyon north of Manitou Springs. In Williams Canyon there were two unexpected Osprey as there is hardly any water here (so likely flying up to Rampart Resevoir)—one perched on a pinyon up on the rim for an hour or so. At least one Prairie Falcon was also around, as well as several Blue-gray Gnatcatchers, and Yellow-rumps (which seem to be everywhere recently), Towhees, a pair of Gray-headed Juncos, Red-breasted Nuthatch, and several Broad-tailed Hummingbirds. Found also my first blooming Paintbrush (Castilleja) and Bluebells (Mertensia) of Spring.

Tuesday (4/29) Middle Shooks Run had an Orange-crowned Warbler along with the many Yellow-rumps around the park recently. Also a Brown Creeper. In the evening another Cooper's Hawk pair along W. Cheyenne Blvd. and a Turkey Vulture roost.

This morning (Wednesday 4/30) I walked in Sondermann Park which was very full of birds. Incredible amounts of Yellow-rumps (mostly Audubon's but a few Myrtle's too), at least three Orange-crowneds, Kinglets, and many (at least 15) Blue-gray Gnatcatchers comprised most of the songbirds. The highlights were my first shining Bullock's Oriole of the season at the far north end of the park and a Peregrine perched on a snag eating breakfast (a Mourning Dove). Also around were Blue Jays, singing House Wrens, Cowbirds, Broad-tailed Hummingbirds, a pair of Mountain Chickadees along with the Black-caps, a Red-tailTowhees, Song Sparrow, many Downy Woodpeckers, and of course countless Mourning DovesRobins and Flickers.

I think that's all. Hope everyone is enjoying the spring.

Happy Trails,

Hi all,

The Long-Tailed Duck female is still there as of sunset today.
I took a grainy picture for those looking to admire her:

Hi all --

The Long-tailed Duck continues as of 4:00 this afternoon.

Shameless pitch: Bluff Lake's bird walk is this Saturday, 8 - 10 am. Should be good -- I've had a gnatcatcher, hermit thrush, cowbird and several other migrants there in the last week.

Official CounterRoger Rouch
Observers: Don Taves



Visitors:
A large group of German high school students on a learning exchange with Wheat Ridge High visited the site but seemed more interested in the views than the birds.

Weather:
A morning blue sky quickly gave way to a mostly cloudy day. A gentle morning breeze, but winds averaging 4 bft. from the NE with gusts to 30 mph from mid-morning on. Temperatures in the 40's all day.

Raptor Observations:
While local Turkey Vultures seem to wander over a wide range this time of year, five were observed to follow a fairly distinct migration pattern. In spite of fairly strong winds from the NE, migrants and a few local Red-tails seemed to glide effortlessly to the north. The last hour of observation was the most active.

Non-raptor Observations:
The observation was terminated slightly early (14:00) due to scheduling complications. Seen or heard, Black-billed Magpie, Western Scrub Jay, Bushtit, Common Raven, Western Meadowlark, chickadee, and numerous White-throated Swift.

Predictions:
Optimistically, lighter winds will be more conducive to migration and more pleasant for the observers.

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.

Collin visited for more than an hour and was helpful in spotting the three migrating birds.

Weather:
Windy, about 20 mph, becoming more calm, between 5 and 10 mph, mid-day. Temperature ranged from 45 deg. F to 49 deg. F. No rain but constant clouds. Much higher wind began at 14:00 hr. MST with darker clouds. Time to leave.

Raptor Observations:
The local Sharp-shinned Hawk flew over the ridge on its way to Green Mountain. A pair of imature Red-tailed Hawks flew by twice. One of the two has an obviously missing 1st or second left wing primary and a center tail feather. The local redtails don't seem to be disturbed by these youngsters' presence. A local redtail was seen often, low on the east side of Dinosaur Ridge.

Non-raptor Observations:
A Hermit Thrush was seen in the juniper brush NE of our platform.

[cobirds] Colorado Springs Recent Sightings 4/28-30 (El Paso)

Hi All,

This is primarily I would think of local interest. No rarities to speak of, but there have been many birds around the Springs recently worth mentioning.

Monday (4/28) there were two Hermit Thrushes at the Colorado College Farm. I found several Cooper's Hawks: a nesting pair on CC campus, an adult male with a kill in Shooks Run Park, and two (one with a kill) in Williams Canyon north of Manitou Springs.

Found also my first blooming Paintbrush (Castilleja) and Bluebells (Mertensia) of Spring.

Tuesday (4/29) Middle Shooks Run had an Orange-crowned Warbler along with the many Yellow-rumps around the park recently. Also a Brown Creeper. In the evening another Cooper's Hawk pair along W. Cheyenne Blvd. and a Turkey Vulture roost.

[cobirds] MacGillivray's Warbler-- Pueblo West, Pueblo Co. 4/30


Mid-day today, there was a male MacGillivray's Warbler (my first of the spring) at Cattail Crossing Pond, in Pueblo West.  Margie Joy came by, and also saw it.  Other things of note:  two Canvasbacks continue, an Orange-crowned Warbler, a Wilson's Warbler, one Yellow-rumped Warbler, a flock of 15 or so White-throated Swifts (new bird for the Cattail Crossing bird list), and four species of swallows (Barn, Tree, Violet-green, and Northern Rough-winged).  This pond is an easy place to see Great-tailed Grackles and Yellow-headed Blackbirds too.  This turned out to be a very productive trip mid-day trip to this location.

[cobirds] Colorado county list updates

Hi everyone,

I will be updating the county lists for the end of April.  If you have any updates for me please send them my way.  If I could please have your updates no later than 5/6.

Also, for those of you who don't use the form (which is absolutely fine and I prefer this method), please put the counties in alphabetical order.  Even though you are not using the form I would appreciate you putting your lists in the order that matches the form.  This is a time consuming task and it only takes longer when things are not in order.  Thank you for your consideration.

[cobirds] Lamar (Prowers) and nearby places of late

It's been windy of late in Lamar, like everywhere else.  But I'll put southeastern CO up against anywhere for meteorological extremes.  We need to invent some new weather descriptors.  Sunday the big, ominous cloud approaching town from the west was the color of milk chocolate.  The small amount of rain that fell was more like dilute mud than anything else.  Ask everybody down here who owns a white vehicle because dark ones get too hot in the summer.  There was a bit of thunder, lightning, and hail mixed in for accent.  The State Patrol closed 287 south of town for at least the second time this year due to minimal visibility.  Somebody somewhere is getting a lot of free dirt.  The City needs to pay stipends, maybe provide lengthy residencies, for creative artists to brainstorm beneficial uses for tumbleweeds.  You have to admit, watching a platoon (division?) of them advance across a field, they are amazing plants.  Night (and day) of the living dead plants.  Botanical zombies.

The word "surprised" was applied to a Broad-winged Hawk seen here yesterday.  NOTHING should surprise anyone who has any experience about this place with birds, weather, or people (with or without binoculars).

Duane Nelson finds a surreal, crisp Hermit Warbler at Tempel's Grove (Bent).  A woman from Rhode Island, who should have been too tired from the demands of her grouse tour led by Norm Lewis, finds a beautiful Golden-winged Warbler trying to blend in among Yellow-rumps feeding in the cottonwood flowers at Lamar Community College.  Mark Peterson finds not one, but two, Summer Tanagers on the ground flipping over leaves on Prowers Rd SS a little east of US287, with Guinea Hens and Peacocks in the background.  Two Gray-cheeked Thrushes have been seen of late, one at a private farm south of Lamar and another at Tempel's (in April, no less).  A very rare spring Rufous Hummingbird watched that chocolate sky last weekend.  Was it really a Broad-tail that flew thru the storm for a make-over?  At least 14 species of warblers have been seen in Prowers and Bent Counties so far (in April, no less).  Never in 40 years of coming down here have I seen so many Hermit Thrushes and Wilson's Warblers in spring as have been present the last few days.  Yesterday a Hermit Thrush was on the ground in a patch of prairie south of Holly where Lesser Prairie-Chickens have been reported, mixing with Grasshopper Sparrows on territory.  Nearby (Prowers Road B west of SR89 about a mile w of the Kansas line) two Mountain Plovers pulled cutworms out of a sparse, muddy wheat field.  Three more Hermit Thrushes were among the depressing dorm foundations in the former Japanese-American Relocation Camp at Amache w of Granada, where there was also a bright male Audubon's Warbler just sitting on the ground and a Least Flycatcher plying calmer air on the backside of a tight juniper windbreak.  Two Willets towered over a mixed flock of blackbirds in a flooded corral within the City limits of Holly.  The pair of Scissor-tailed Flycatchers reported near a motel in Holly could still be present.  Certainly super windy conditions require them to do something special in deference to those posterior plumes.

Getting back to Hermit Thrushes and Wilson's Warblers, every good patch of habitat has multiples of both.  It is like the south winds that preceded these relentless north winds brought them in, then sentenced them to three days of evolutionary boot camp trying to survive by hiding down low on the south side of understory vegetation eating whatever they can find. 

Anyone who thinks birds aren't tough, needs to have been outside the last couple days.

[cobirds] Cedar Waxwings

Along with our f.o.y. broad-tailed hummingbirds yesterday, our backyard was visited by a flock of ten cedar waxwings, who descended on an apple tree that is in full bloom.  They picked at the apple blossoms, along with a dozen pine siskens, several goldfinches, a few house finches, and a couple of black-capped chickadees--all picking at the apple blossoms.  It was a most busy tree.  Anyone know what they might have been eating?  Link to cedar waxwing pic:  http://www.wunderground.com/wximage/flowerman/378?gallery=EDITORSPICK

[cobirds] Broad-winged Hawk in Lamar

Birding was near impossible with the strong wind gusts up to 63 mph and nasty dust storm today in Lamar.  I was surprised to see a Broad-winged Hawk flying near a residential area this morning before I gave it up.  I spotted it a little later as it flew in to perch.  I got some very good photos of it that I have uploaded to my Birds and Nature blog.

[cobirds] Checking In from Golden

It's been a while since I've posted, and it's also been a while since the birds were active on the Colorado School of Mines campus. Recently, Lesser Goldfinch, Broad-tailed Hummingbird, American Kestrel, and Cliff Swallows have returned. Red-tailed Hawks and Turkey Vultures are soaring almost daily. Also, I've had a couple flyover grackles that I'm not confident calling between Great-tailed and Common, thoughts?

Continuing: I'm fairly sure there are at least three Northern Flicker territories on campus, though I've seen them range well over a hundred feet as they look for food. House Finches and European Starlings love sitting in the tops of trees, and there are also at least four members of the finch choir across campus. A Robin can be heard singing every morning and evening. When I walk into downtown, the finches are everywhere. Collared Doves seem to show up whenever they please and give a few coos from time to time. Geese have cleared out for the most part. And Kestrels may be nesting by the old Ford dealership on 19th.

Good Birding,
Elliott Gordon

[cobirds] Long-tailed Duck, Rocky Mtn Lake, Denver county

COBirders,
I dropped by I-70 & Lowell and confirmed Bob Canter's Long-tailed Duck amongst the white caps this morning around 10 am.  It was hanging with Ruddy Ducks.  It appears to me to be a female that hasn't quite completed the molt into alternate plumage but my experience with this species is also limited so I can't be sure if it is leaving juvenal plumage or just basic plumage.  The wind sure didn't help either as she stayed tucked most of the time. 

As windy as it was, there were also quite a few swallows (200?) on the lake.  Most were Cliff and Barn with at least 2 Northern Rough-winged and more Violet-greens than eBird liked (at least 8.)  No Tree or Bank Swallows that I could discern.  A few usual suspects brought the list to 19 species in 20 minutes.

Happy spring,
Chip Clouse
Olde Town Arvada, CO

[cobirds] black-throated gray warbler, dixon reservoir, fort collins

had a black-throated gray warbler this morning at Dixon Reservoir, presumably the same as the one reported by Brad Biggerstaff yesterday.  this was a male with jet black throat but the yellow spot on the face was hardly visible/noticeable. 

the bird was hanging out in the lee (East) side of the forest, near the water, along with several yellow-rumped, bluegray gnatcatchers and a ruby-crowned kinglet.

[cobirds] Marston Reservoir shorebirds, Denver

Although arriving at the "Isthmus Park" on the south side of  Marston just after a Bald Eagle flushed most of the birds this morning, I still was able to find 4 Marbled Godwits and three Willets on the shore.  To reach this small park take W. Grant Ranch Blvd. to S. Jay Circle.  Walk in and view from the gazebo for a fence free vista.

[cobirds] water forum in Boulder: not just for shorebirds & ducks

Dear CObirders, 

This topic could be construed to be tangential to Colorado birding or… absolutely essential.

Ever meet a bird that did not need water to survive?  Me either. My Atlas II block was in SE Colorado — the need for water for all of us was really painfully obvious there.

This informational seminar is free (as far as I know), and has some terrific presenters, as well as an appearance by a guy who authored the best book I’ve ever read on water management in the West: Eldorado Springs’ own Stephen Grace. (To imitate Joe Roller’s style, I wish to assert that it was lyrical and witty —  not a dry book!! )

Audubon lobbyist (former and now the Eminence Grise) Jo Evans will answer many burning questions (like, why can’t I use my own gray water—don’t we public citizens own the drops of water that fall from Colorado skies?) Allison Hollran will speak about our (arguably) most relevant CObirds issue: Conservation of Ecosystem. See notes below for a more complete list.

No disclaimer; event is free and I get no commission. BC Audubon had a presentation (by Jo) on water a few weeks ago and the audience could not stop asking questions. Come armed with your own.

I hope our moderator will show suppleness in admitting that this could be important for us to consider. Thanks to all, and see you there—

[cobirds] RMBO Banding at Chico Basin Ranch, El Paso Co.

Spring migration bird banding at Chico Basin Ranch (fee area) commenced on Wed. April 23rd.   We have banded 90 individuals of 17 species thus far.   It's been just the usual cast of characters for April, except for a Gray Flycatcher on the 24th - we rarely get these in spring (only four since 2002).  No Long-eared Owls seen or banded yet - unusual compared to the past three years.  It was too windy to open nets this morning.

[cobirds] Chatfield and Deer Creek Canyon parks (Jeffco/Douglas)

Back to Chatfield this morning. A LEAST FLYCATCHER was on the west side of Kingfisher Bridge, providing delightful views. The EASTERN PHOEBE there was immediately evident as I walked across the bridge and it very nearly got hit by a passing car when it chose a risky moment to fly low across the road. Why did the phoebe cross the road? To join its mate! It flew across and perched close by another Eastern Phoebe along the edge of the South Platte. And the Eastern Phoebe over at Plum Creek Picnic Area is also paired, as both were there together this morning, in trees close by the restroom. 

Back at South Platte on the west side upstream of Kingfisher Bridge there was a female BLACK-THROATED GRAY WARBLER. Also noted there were 1 or 2 Ospreys, an adult Bald Eagle, and a Blue-gray Gnatcatcher. Another Osprey was near the Chatfield Dam, and a Rock Wren was at the west end of the dam.

Rattlesnake Gulch Trail at Deer Creek Canyon Park had a PLUMBEOUS VIREO, about 20 Broad-tailed Hummingbirds (mostly displaying males), 2 Virginia's Warblers, 4 Blue-gray Gnatcatchers, 4 Lesser Goldfinches, and quite a few singing Ruby-crowned Kinglets.

Just as a minor addendum, around 8:30am there was a pair of Evening Grosbeaks hanging around in the creekside trees opposite the scoreboard area as well.

[cobirds] Link to possible Bendire's Thrasher photos from April 24, Las Animas County

Photos are now available for review for the reported Bendire's Thrasher south of Higbee, CO. The photos were taken by Linda Pittman of Sacramento, CA during a brief encounter with a medium-sized thrasher that crossed the road from east to west in front of our van, and then alighted atop a cholla cactus. From there it flew to another cholla and then to a dirt mound before flying off to the west. It never sang. The encounter lasted long enough for me to get out and set up a scope on it. This occurred at a bridge over a dry wash. At the roadside by the bridge were numerous large seed pods strewn along the road, resembling silver Christmas tree ornaments. The GPS coordinates were +037.60273, -103.33090. On Google Maps, the wash is labeled "Lindsey Canyon" and is located about 10 miles south of the Purgatoire River on Hwy 109, about midway between La Junta and Kim.
 
The photos are low quality (I am amazed Linda was able to get any photos at all!). They can be reviewed on-line at   http://lsp.smugmug.com/Photography/Colorado-2014/. I am afraid that the photos themselves do not identify this bird, but I do think that they corroborate (especially image #5, IMG1783_1) what we saw in the field (or maybe I am using my imagination, i.e. wishful thinking!). I believe they show a bird that is plain-winged, with a heavy but short bill that puts the bill between that of Sage and Curve-billed Thrashers. Furthemmore, the photos fail to show a dark malar. Both Curve-billed and Sage, unlike Bendire's, should show wing-bars and a blackish malar. Anyway the photos are available for Cobirds readers to view and draw their own conclusions. I will submit some of these photos along with a description to the CBRC for documentation purposes, although I don't expect these photos are adequate to support our claim of Bendire's Thrasher. Hopefully, it sticks around and can be appropriately documented.

DFO meeting Monday April 28, featuring Nathan Pieplow. “Five Audio ID’s every Colorado Birder Should Know”, Nathan will talk about how to separate the sounds of Williamson’s and Red-naped Sapsucker; the drums of Three-toed Woodpecker; the songs of Dusky, Hammond’s, and Gray Flycatchers; the winter calls of Horned Lark, American Pipit, and Sprague’s Pipit; and the calls of Common and Chihuahuan Ravens. A brief quiz at the end of the evening will help cement the skills in our brains. NOTE: The DFO meeting is in the Denver Museum of Nature and Science Planetarium. Enter through the north door by 7:30 p.m. We must lock the door a little after that time.

DFO Field Trips

Saturday May 3, 2014
South Platte River Trail
Leader: Jackie King, 720-381-3314

Meet leader at the parking area at 88th and South Platte River Trail at 9 a.m. From I-76 take E. 88th Ave. exit, go west on 88th for 1.6 miles then turn south at Colorado Blvd. Turn left again into the parking lot for the South Platte River Greenway Trailhead. This trip will be a half-day trip so bring water and snacks; lunch is optional. We will walk along the trail and see which migrants are there as well as enjoy the many resident birds that should be back. Leader uses a wheelchair for mobility so it will be accessible and easy, level walking. Good trip for new members and novice birders.

Sunday May 4
Brett Gray Ranch, Lincoln County
Coleaders: Mark Amershek and Bruce Neuman


Trip will be limited to 10 persons: please RSVP Mark at 303-329-8646 or <mamershek@msn.com> before May 1st. Meet and carpool at 5:45 a.m. at the KingSoopers parking lot on Fountain Parkway (just east of I-25) in Castle Rock, CO. Carpools will leave at 6 a.m. sharp. We need volunteers to drive (high-clearance, 4-wheel-drive vehicles); let Mark know if you can drive.

Brett Gray is a 49,000-acre Nature Conservancy working ranch location in Lincoln County (southeast of Colorado Springs). The driving distance from Castle Rock will be approximately 100 miles (a little over two hours).

The ranch will be birded by following the ranch roads in cars with stops to bird on level open areas (ponds, wetlands, grassland, and small creeks). This ranch is similar in habitat to the Chico Basin Ranch with two dam ponds and wooded areas. There are no restroom facilities at the ranch or nearby, so we will stop in East Colorado Springs on our drive down and again on our way back, plan accordingly. This will be an all-day trip so bring water and lunch. Scopes would be handy but not necessary. Two-way radios per car would be helpful. We will bird until 4 p.m. and should be back at Castle Rock about 6 p.m. 

 
 
Good Birding,
Mary Driscoll
Unincorporated Arapahoe County

Observers:



Visitors:
The only visitor was a man, with his dog, who stopped briefly for the view and commented on the wind.

Weather:
The day was mostly sunny with spotty cloud cover. The wind, mostly from the northwest, was unrelenting at bft 5 with gusts reaching bft 6 and calmer moments at bft 4. Visibility was generally good except for a periodic brown haze that would hang in front of Mt. Morrison due to dirt and dust blown up from many places, including the quarry. There appeared at times to be some light rain further south along the Ridge as well as along the top of Green Mountain.

Raptor Observations:
The two migrants, a female American Kestrel and an adult Turkey Vulture, came early and at about the same time. Both travelled close to the Ridge. There was a fair amount of local raptor activity in spite of the wind. A local Cooper's Hawk was observed over the valley to the West of the Ridge. Local Turkey Vultures traversed West Ridge and Mt. Morrison. Local Red-tailed Hawks were observed over both valleys from WestRidge to Green Mountain. A local Peregrine Falcon and much later a local immature Golden Eagle were seen high to the south over the Ridge. A local Prairie Falcon was seen a few of times, northwest of the platform to high to the south. Later in the morning, a local male American Kestrel fought the wind to fly west, dropping low below Mt. Morrison perhaps to hunt.

Non-raptor Observations:
Approximately 40 White-throated Swifts passed the HawkWatch site heading north, seemingly not bothered much by the wind; about 10 or so appeared to be staying in the area. Also seen and heard were Yellow-rumped Warbler, Violet-green Swallow, Broad-tailed Hummingbird, Black-billed Magpie, American Robin, Western Meadowlark, American Crow, Common Raven, and Mourning Dove.

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.

"Quest for 100 Species"

Join John Vanderpoel for this most promising time of spring when the migration of the waterbirds and passerines overlap. You will explore many hot spots in Boulder County, including a wonderful private estate adjoining Panama Reservoir. Species expected include the sandpipers, stilts, avocets and perhaps a Long-billed Curlew, as well as early warblers, grosbeaks, tanangers and ducks in their brilliant breeding plumages.  Meet at 7 a.m. at Walden Ponds on 75th Street. Bring a lunch and water and be prepared to walk several miles.  No reservations needed, but we do hope that you will car pool!

[cobirds] Chatfield SP Hildebrand Ranch Park (Jefferson/Douglas) and Marston Lake (Denver)

Today (Apr 28) along Deer Creek at Hildrebrand Ranch Park there was a male BLACK-CHINNED HUMMINGBIRD, as well as my 1st Orange-crowned Warblers of the season and a Green-tailed Towhee. 

Two WHIMBRELS flew north over the South Platte arm of Chatfield, while I stood near the river's inlet into the reservoir. They were calling and afforded a decent view even though they passed over at a moderate height, flying strongly into the brisk wind. Two American Avocets and a Spotted Sandpiper were also at the Platte inlet. An EASTERN PHOEBE was along the path immediately east of Kingfisher Bridge. And another EASTERN PHOEBE was at the Plum Creek Picnic Area; it was moving between the restroom and bridge. Both phoebes were silent. A LEAST SANDPIPER was at the marina sand spit, and a flock of about 185 American Pipits were feeding at the spit. They just kept coming and coming up out of the grasses and low weeds there as I approached. An OSPREY was soaring over the lake. Plum Creek Nature Area had a Blue-gray Gnatcatcher and a Common Yellowthroat. 

Yesterday (Apr 27) at Marston Lake I saw a COMMON LOON and a SEMIPALMATED PLOVER. Bird numbers were a good deal lower than on my prior visit last week.

[cobirds] Red-breasted Merganser, El Paso Cty

Eric and I stopped by Prospect Lake (Colorado Springs) briefly today.  The wind chased us away from a mostly empty lake pretty quickly, but not before we got good views of a female Red-breasted Merganser.  I'm not sure if they are considered rare enough for this list, but I've never seen one before. 

Here is my best shot: https://www.flickr.com/photos/29823227@N03/14077284733/
