Visitors:
We had 74 Visitors to the ridge today. Three of them were small children who were able to look through our binoculars to see mule deer close up.

Weather:
Today was a partly cloudy day full of fairly strong winds and the haze again today.

Raptor Observations:
Today we got a new highest count for the year. There were a lot of accipiters and for the most part migrants were low today. We had a kettle of 5 turkey vultures, a first year red-tailed that had both juvenile and adult plumage, and a probable male sharp-shinned hawk fighting the wind more than some of the others we saw. We had a local Red-tailed hawk chase a common raven away from its nest, and probably a different red-tailed hawk catch a mouse and eat it on a telephone pole. We also had a local Turkey vulture and a sharp-shinned hawk with full crop.

Non-raptor Observations:
We had a large group of Woodhouse's Scrub-jays, a few Black-capped Chickadees, a couple Mountain Bluebirds. There were a couple groups of mule deer found to the west, the east, and on our ridge on the western side.

Predictions:
Tomorrow looks to be full of rain and possibly storms. I'll look again tomorrow but a shortened count tomorrow is likely.

Site Description
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is the
best place in the world to see migrating Ferruginous Hawks. Hawk watchers may
see 17 species of migrating raptors; and it is an excellent site to see rare
dark morph buteos including Broad-winged hawk, Swainson’s hawk, Ferruginous
hawk, Rough-legged hawk and Red-tailed Hawk. Other raptors we see include Golden
and Bald Eagles, Northern harrier, Osprey, Peregrine Falcons, Prairie Falcons,
Cooper's and Sharp-shinned Hawks, American Kestrels, Merlin, and Turkey
Vultures. American Goshawk is uncommon but also counted each season. Non-raptor
species include Rock Wren, Bushtit, Western Bluebird, Sandhill Crane,
White-throated Swift, American White Pelican, and Dusky Grouse. Birders of any
skill level are always welcome. The hawk watch at Dinosaur Ridge is staffed by a
Hawk Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

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 hawk watch signs from the
southwest end of the parking lot to the hawk watch 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, and walk to
the flat area at the crest of the ridge. (Distance: 0.56 miles, Elevation gain:
259 feet)

[cobirds] Snipe winnowing northern Boulder County

I just heard the first winnowing snipe of the year to the north of St. Vrain Road, between 75th and Rte. 36.

Re: [cobirds] Common Grackle

I was birding at Hudson Gardens yesterday morning and saw a Common Grackle at the feeders.
We also saw a couple of Cliff Swallows over the Platt River - first of the season.
They're back !

[cobirds] California quail (but maybe an escapee) for your list

Hi Thomas,

A California quail appeared in my yard on Baseline Road in the early 1960s. I was taking an ornithology class from Dr. Gordon Alexander at the time, and he said it might have been an escapee, which seems probable. Are you counting escapes?

Over the 60+ years that I've been birding, there have been so many memorable moments. When we lived on Mariposa, Bluebell Creek ran in the backyard and was like a highway for wildlife. Once I heard a bird song and said, "If I didn't know better, I'd think that was a cardinal." It WAS a cardinal—a female. First time I realized female cardinals sang. When we first moved there in 1973, Steller's were the only jays.Then blue jays moved in and were dominant until the scrub jays arrived and lorded it over the other two species. Scrub jays would come to the bathroom window to remind me to replenish the peanuts.

A brown thrasher once spent the winter near our feeder when we lived on a slice of land surrounded by Teller Lakes Open Space. While we lived there we got a few one-day wonders: sage sparrow, red-headed woodpecker, and yellow-billed cuckoo. We occasionally had peregrine falcons and sandhill cranes and often saw osprey and bald eagles. Isn't it wonderful that bald eagles are now almost common!

My most memorable moments were during the six years when a pair of Swainson's hawks nested in a willow very near the house and successfully raised young each year. The protective parents were o.k. with us until the young fledged. Then they became so belligerent that I had to carry an umbrella to flourish when they dive bombed me. Or, maybe the most memorable moment was the time during a light rain shower when a great horned owl, who had been incubating in a nest near our home, decided the endeavor had failed. She flew up to branch, lifted her wings, took a long shower, and left. The male stayed around the nest for several days, sometimes looking into it and appearing disconsolate.

Now that we live in a retirement community, I'm thrilled just to get a kestrel perching on the balcony railing.

A mouse (or kestrel) is miracle enough,
Ruth Carol Cushman

Visitors:
We had 43 visitors to the ridge today. We have had a lot of visitors the last couple days wearing Chicago cubs (baseball) gear. Which I thought was an interesting observation since they were not playing the Rockies, and as a St. Louis Cardinal fan we had some fun banter.

Weather:
Today was a warm mostly sunny day with strong winds that changed from a Southeast to a Northeast throughout the day. There was a bad Haze over the entire area especially to the south of us.

Raptor Observations:
Most of our migrants were very low today. Even our far away migrants were close to the horizon. We had our first loose kettle of 3 turkey vultures, and a coopers hawk that was momentarily thwarted by the wind before moving north. We had an immature bald eagle do what I call the wave (or saw) technique while migrating that I have mostly seen in Red-tailed hawks. Going into a head-wind the raptor tilts its wings up to gain height before diving down and forward then repeat. This gains distance without having to flap, and usually only lasts for a few minutes. The unknown accipter was about a mile and a half away (under cabrini shrine) and was under eye level the entire time. This bird flapped a lot (uncountable), but the flaps looked stronger. This bird was most likely a Cooper's Hawk, but I couldn't be sure it wasn't a Sharpshin as the far away, brown bird had a green/brown grass background where it was disappearing for a few feet before reappearing. We had an evening surge of kestrels where we had 6 migrating kestrels after 3 MST (4 MDT). Today we had a local Turkey Vulture, Merlin, year 4 Bald Eagle, and an accipiter probably a Coopers flying south to the east of us under a migrant red-tail (So I looked away before an ID was made).

Non-raptor Observations:
Today we saw my first ever white-throated swift!! This bird was by itself and flew north as a non-raptor migrant. We also had mule deer on green mountain again, and saw a person in a parachute from pretty far away.

Predictions:
Tomorrow looks to be a warm and overcast day with a strong southwest/ tail-wind. Should be a great Easter, and I look forward to seeing those who will join me on the ridge and maybe their families.

Re: [cobirds] Common Grackle

Same thing over here at Ken Caryl - my first home area Common Grackle for the season was noted this morning. My yard average first of the season is March 28 (range for 10 years March 23 - April 2). Thanks eBird. I appreciate their regularity, if not their bird seed appetite.

[cobirds] Sagebrush Sparrow in Otero County 3/30

Van Truan and I saw and photographed a Sagebrush Sparrow, not too far west and south of the Cactus Wren location this morning.  This is in southern Otero County.  This ebird list is where we saw it.  


We saw a Snowy Plover at Lake Cheraw, two Baird's Sandpipers and three American Avocets at Lake Meredith in Crowley County.  Those were are only shorebirds, other than Killdeer.

Good birding,

[cobirds] Speaking of yard birds....CO Combined Yard List update

Hi all,

With the latest additions of Mexican Duck (from three yards!), Glossy Ibis, and now a solid Boreal Owl report (from Jack Bushong), the total is 402 species! Still hoping to get more info about the Lesser Black-backed Gull that was added to Bryan's list a couple of weeks ago.  

The list is almost ready to go "live" (rhymes with hive) on Google Sheets, hopefully by tomorrow.  I've been working with Bryan over the last several days trying to refine and streamline it. We've been discussing various options of what to include, how to link data, etc.

More later....

Thanks to all for sharing and contributing! 

--Thomas

[cobirds] Eastern Phoebe / Phoebes? - Arapahoe

This past week, I taught a sociology course on urban wildlife at DU. It's more about the human dimensions of urban non-human species than the ecological ones. But students and I spent a bit of the course birding around the suburbs of Denver.

On Thursday, we encountered an Eastern Phoebe along the High Line Canal in the Greenwood Village / Centennial area. On Friday, I swore I heard another one along the S. Platte River in Littleton -- along the Mary Carter Greenway trail on the north edge of Eaglewatch Lake. But it was the end of our time out, and I was gathering students to leave. So I didn't spend any time confirming what I heard.

[cobirds] Statistics

Although our yard list (101) pales in comparison with many others, I submit another statistic. In our birding career, Jeane and I spent nights in 37 Colorado cities and towns.  Some numerous times.  We did our part for the local economies.

Visitors:
We had 14 visitors to the ridge today, one person might become a member of the Denver Field Ornithologist along with his father who wasn't there.

Weather:
Today was a very overcast day that got colder as the day went on. The wind started from the Southeast and shifted to the Northeast. It threatened to rain on us and multiple times we had very light rain or snow that we could see, but not really feel. In the last hour, it switched to an off and on light drizzle, but my persistance was rewarded.

Raptor Observations:
Our migrants were mostly straight above us and close due to the low clouds and almost constant precipitation around us. As we were watching a migrating red-tailed a second red-tailed appeared roughly 3 times higher up than our migrant. The higher bird tucked its wings and dove straight at the migrant. When the local bird made contact there was a small puff of little feathers came off the migrant. The local attacked many times before it turned around leaving the migrant to go north. Our first Sharp-shinned hawk was very tiny suggesting that it was a male. This hawk was about 40 feet slightly above eye level. We saw a pair of Red-tailed Hawks, what I believe was a different pair than the day before, copulate along the western ridge.

Non-raptor Observations:
We saw lots of moving passerines in all directions. Mostly American Robins and Mountain Bluebirds, but there were a few where none of us saw the species. A few mule deer were within 60 feet away from me on the way down the trail.

Predictions:
Tomorrow we should have a sunny day with an ever changing wind. The trail should be muddy in the morning and dry out pretty well over the course of the day. Bring some sunblock and I'll see you up there.

Site Description
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is the
best place in the world to see migrating Ferruginous Hawks. Hawk watchers may
see 17 species of migrating raptors; and it is an excellent site to see rare
dark morph buteos including Broad-winged hawk, Swainson’s hawk, Ferruginous
hawk, Rough-legged hawk and Red-tailed Hawk. Other raptors we see include Golden
and Bald Eagles, Northern harrier, Osprey, Peregrine Falcons, Prairie Falcons,
Cooper's and Sharp-shinned Hawks, American Kestrels, Merlin, and Turkey
Vultures. American Goshawk is uncommon but also counted each season. Non-raptor
species include Rock Wren, Bushtit, Western Bluebird, Sandhill Crane,
White-throated Swift, American White Pelican, and Dusky Grouse. Birders of any
skill level are always welcome. The hawk watch at Dinosaur Ridge is staffed by a
Hawk Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

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 hawk watch signs from the
southwest end of the parking lot to the hawk watch 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, and walk to
the flat area at the crest of the ridge. (Distance: 0.56 miles, Elevation gain:
259 feet)

[cobirds] Hairy Woodpecker (Wheat Ridge, CO/Jefferson County)

I am reviving this old thread. I think I may have seen the same bird at Prospect Park near the parking lot. See attached photo. I had no idea some Hairy Woodpeckers could look like this.

Terri and all,

Very interesting; thank you for sharing. 

Here's what i found online from Garth Spellman, when looking at a similar photo:


Garth Spellman, the curator of ornithology at Denver Museum of Science and Nature, gave this reply when I inquired about his thoughts on this Hairy:

 

Looks like this individual has a problem with its melanin pathways. Black plumage is normally straight melanin and browns or tans are phaeomelanin. Oftentimes birds have problems or develop problems in these pathways that can lead to aberrant plumage. This can often happen in older birds, but not always. The brownish color actually looks like the same color found in Hairy Woodpeckers down in Panama (yes they get all the way down there). The subspecies in Panama is small and brown."

At Wheatridge Greenbelt today (near the Prospect Park parking lot), I found this Hairy Woodpecker with chocolate brown tail feathers. From what I find, this coloration is more common in the Pacific Northwest.  Does anyone have more information?  Definitely a first for me and hoped it would be interesting to others.

Visitors:
We had 25 visitors to the ridge today who varied from super interested to being downright disrespectful and went off trail despite the directions we gave. Hopefully, we will see most of these visitors again.

Weather:
Today was a very sunny day. The sky was cloudy most of the day, but the clouds were very thin and wispy. It gave a nice background to view migrants. The wind started from the Southeast, and it switched to an eastern (cross-wind) which did seem to affect migration.

Raptor Observations:
Most of our migrants were directly above us or to the west of us. We had two local Turkey Vultures one of which was a juvenile. One of the two turkey vultures was being hounded and attacked by a Red-tailed hawk. We saw Red-tailed hawk courtship a few times, and a local male kestrel flying south.

Non-raptor Observations:
We saw the same raven pass by at least four times. We could tell it was the same one because it was missing 2 or 3 secondary flight feathers. We had my first on the ridge Stellars Jay today that stuck around for a few moments. We also had a herd of about a dozen elk, and another herd of about 15 mule deer both around bare slope.

Predictions:
It's possible I looked at tomorrow's weather for this section yesterday. It looks to start raining around 1 and keep raining the rest of the day. The temperature looks to be in the 40s with a moderate wind shifting from the east to the north. I'll be up there until the rain is super strong, or it becomes clear that nothing is moving in the rain. As always if it builds into a thunderstorm we will leave the count early.

Visitors:
We had 7 visitor to the ridge today, a few of which I believe will come back and see us again.

Weather:
Today was a great day weather day. There was a Northwestern wind all day and temperatures fluctuated with the wind. We appeared to have a consistent surface wind, and most of our migrants were able to fly above the wind with little trouble.

Raptor Observations:
Most migrants in the morning were very high over the headwind. Once the winds got stronger the migrants were lower and struggled more. In the morning we had a harrier chased south by a couple red-tails and a Turkey Vulture fly due west. A golden eagle tried to head north to the west of us and got chased by a pair of red-tailed hawks. He then tried to head north along our ridge and got chased back south by another pair of red-tailed and we didn't see it again. Later on a Sharp-shinned hawk appeared to try and migrate and got thwarted by the wind. It tried a few times before appearing to give up and settle by mount morrison. We saw a local Red-tail carrying a vole (small rodent) two different times today about 4 hours apart. We later saw two red-tailed copulating to the west of us.

Non-raptor Observations:
We had a few Townsend's Solitares hanging around the ridge all day. There was also elk along bare slope where they usually hangout.

Predictions:
We should have the temperatures in the mid-forties with a shifting wind from the southeast to the North. With that shift in wind there will be rain starting around 1. Depending on the strength of the rain and how the sky is looking will determine if we shorten the count tomorrow.
