Visitors:
17 Visitors. It was fun to watch the mountain bikers come up the trail in the high winds today. We also met a hiker celebrating his birthday. Thank you to Kathie Moses and Cayce and Chris Gulbransen for volunteering today! We appreciate you both for your spotting and for your company.

Weather:
It was a warm and windy day today. Winds were light to moderate, generally from the west, for most of the morning. Humidity was very low throughout the day, reaching 6% RH at one point. Temperatures peaked in the mid 80s in mid-afternoon, before the cloud cover returned and west winds intensified. The wind continued to pick up until the count was ended at 15:15 MST due to high winds.

Raptor Observations:
It was a surprisingly slow day for migration with only 6 birds seen on the total count. Our first bird was a Sharp-shinned Hawk was seen in the first half hour struggling in the winds. Most birds today were overhead, including two juvenile Red-tailed Hawks and a Cooper's Hawk, but we also had a distant American Kestrel to the west and one on the east. Local RTs were kiting in the wind for most of the day - we watched a local RT attempted to fend off a raven while carrying a large snake. There was a lot of swift and swallow activity today, even in high winds. A few Steller's Jays and a sapsucker flew past quickly in the early am.

Non-raptor Observations:
White-throated Swift 10, Broad-tailed Hummingbird 3, Mourning Dove 1, Double-crested Cormorant 1, Red-naped Sapsucker 1, Steller's Jay 2, Woodhouse's Scrub Jay 6, American Crow 1, Common Raven 2, Violet-green Swallow 45, Barn Swallow 2, swalow sp. 50, Rock Wren 1, Blue-grey Gnatcatcher 1, American Robin 1, House Finch 2, American Goldfinch 1, Pine Siskin 1, White-crowned Sparrow 1, Spotted Towhee 1, Western Meadowlark 2

Predictions:
Tomorrow, expect cooler temperatures in the 50s F with sun in the morning and increasing clouds in the afternoon. Winds are forecasted west from 15-20 mph with possible gusts of over 30 MPH.


Report submitted by Official Counter of the day shown above (dinoridgehw@gmail.com)
Dinosaur Ridge - Denver Field Ornithologists information may be found at: www.dinosaurridgehawkwatch.org
More information at hawkcount.org: [Site Profile] [Day Summary] [Month Summary]
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)

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,

[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?
