Re: [cobirds] Follow-up on Cherry Creek SP Harlequin Duck report?

Around 5pm, I biked the length of the dam trail and all around the marina / picnic area, but dipped on the Harlequin duck. However I did have my FOY water maggots / jet skis

Good birding,

Hi all,

even after including rarities I can't find a way to report my sighting of the Harlequin Duck on eBird.

Help?

Thanks

[cobirds] House Wrens -- with just one, I rejoice

With many, I get weary. But I'm glad the wren houses are up & ready, as well as the swallow boxes (we've never had a bluebird, alas). Also, our Black-chinned Hummingbird has made his first appearance, unless he was on a hurry north, like the one Pam heard. We have a few Broad-tailed out here in the prairie, but they won't stay. I'm enjoying spring news from everyone, especially John T's wonderful broad survey from a few days back.

Re: [cobirds] Astero Res in Park Co. to be drained & closed-? impacts

The White Pelicans no longer nest at Antero, I don't think, but they do visit there. They nest on an island at "nearby" Eleven Mile. And those in South Park seem to mostly remain in South Park, not to say that couldn't change. There are also foraging impacts for California Gull and some others, and nesting impacts for Eared Grebe, which uses Antero, and some nesting shorebirds including Snowy Plover. And lots of other changes that will result from de-watering the reservoir. But it was dry for two or more years recently when there was work on the dam, and things returned to a good condition after water was returned. In a time of such a water shortage, what really could be done?

While Denver Water, which owns Antero Res., is working with CPW to minimize negative impacts to fish by relocating them to other lakes I don't see any consideration or minimization of impacts to Am White Pelicans that nest around Antero Reservoir every year (there are ebird reports of Pelicans seen there already).

No, I am not aware of what mitigation could be done but it certainly should be explored and some discussion of conflicts when bunches of Pelicans (that eat large amounts of fish) decend on other lakes. I remember when the owner of a private lake in Buena Vista began shooting at the Pelicans because they were eating the fish he paid to stock in his lake until told by CPW he could not do that without a depredation permit' from USFWS. The lake owner applied for the permit but it was denied. The problem was addressed with CPW providing the lake owner with non lethal products to harass the Pelicans off the lake.

I will contact CPW about this issue. Does anyone have any ideas on mitigation?

[cobirds] BIRD BOMBS: At the Feet of the Foothills explodes this Thursday Apr 23 at 7 pm

Hi CoBirders,

Register now for the DFO's next BIRD BOMBS explosion Habitat Blast: At the Feet of the Foothills, set to go off this Thursday April 23 at 7 pm (MT). Join this free Zoom webinar and learn about the bird communities of the hogback zone and the lowest foothill slopes. We'll focus on the Front Range and Rampart Range region, but the presentation will apply to similar settings elsewhere in Colorado, too. This strip of Colorado includes some of our most beloved parks and birding spots.

View the whole BIRD BOMBS video library here and on the Denver Field Ornithologists' Youtube channel.

Observers:

Visitors:
3 visitors. Although visitors were few in numbers today, we enjoyed spending time watching the birds with them. Thank you also to Derek Freed and Chip Dawes for volunteering today! Today was truly a team effort with the distant high birds.

Weather:
It was a hot and sunny day. Temperatures quickly rose to the low 80s F where it remained for the rest of the day. In the morning, clouds were few but by the late afternoon there was a thin wispy cloud layer in addition to scattered denser clouds. After a brief hour or so of light west wind, winds were light to moderate from the southeast, at their most intense during midday and early afternoon. During the final hour of the count, wind occasionally gusted from the west before switching back to east.

Raptor Observations:
Raptors definitely took advantage of the sun and warm temperatures today, and even local birds were high up within less than an hour of the count start. Most Broad-winged Hawks today were seen in the first full hour of the count quite distantly, but we had one later glide overhead relatively close midday as well. Sharp-shinned Hawks made up the majority of the accipitrines we saw today, moving throughout the day. A few Swainson's Hawks, including a dark morph, were seen in the afternoon. Unlike prior days, only a few migrating American Kestrels were seen towards the end of the count. Outside of raptors, we had two small groups of Franklin's gulls overhead - one group so close that you could see their pinkish tinge!

Non-raptor Observations:
Canada Goose 2, White-throated Swift 3, Broad-tailed Hummingbird 3, Mourning Dove 3, Franklin's Gull 40, Double-crested Cormorant 1, American White Pelican 4, Say's Phoebe 1, Blue Jay 2, Woodhouse's Scrub Jay 1, Black-billed Magpie 1, American Crow 2, Common Raven 2, Black-capped Chickadee 1, Tree Swallow 3, Violet-green Swallow 1, swalow sp. 1, American Bushtit 3, Rock Wren 1, Blue-grey Gnatcatcher 1, Red-breasted Nuthatch 1, House Finch 3, American Goldfinch 1, Spotted Towhee 1, Western Meadowlark 1, Red-winged Blackbird 2

Predictions:
Tomorrow, we expect similar high temperatures and sun. Winds from the southwest are predicted, light to moderate in the morning but stronger in the afternoon, with possible wind gusts of 30+ MPH. Make sure to bring lots of water and sunscreen!

Count data submitted via Trektellen.org - [Project Details]

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, and American White Pelican. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by Hawk Counter(s)
and volunteers from March through early 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 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] More birds in Golden-Jeffco

Fortunately the bird action has improved since I was complaining about it.

Our FOS birds are:

House Wren

B. Oriole (heard)

Am Goldfinch (alternate plumage)

Others are singing and it is much nicer than before.
