[cobirds] DFO's slate of June field trips open for registration May 1

CoBirders,

DFO's Big Year 2018 is charging ahead, with plenty of trips to offer lots of great opportunities. While still awaiting all reports from the several trips that went out last weekend, we are surely well past 230 species. 

Our full slate of June field trips will become available for registration on Tuesday morning May 1. In June watch for several overnight trips out of the Metro Area, as well other great trips. All trips are free. You can register here:


Note also that there are still spaces available on some May trips, including two open spots on a very well-timed (we hope) overnight trip to Southeast Colorado on May 8-9 (please contact me if you sign up so I can provide important details), and openings on a few other May outings.

Observers: Richard Cuellar



Visitors:
Only a few hikers came up to the platform today, only for the view. One young man, who had hiked north along nearly the entire Ridge, inquired where the dinosaur footprints were, as well as the quickest and easiest way to get back there.

Weather:
The day was partly cloudy, with cloud-cover increasing from an initial 30-percent (mostly at the horizons and to the east) to about 60-percent coverage (shifting, scattered cumulus interspersed with thin, higher clouds). Relatively mild winds of bft 2-3 came initially from the east but shifted about halfway through the watch to come a bit more forcefully (bft 3-4) from the northeast and north-northeast. The temperature rose from 15 C to 19 C before the slightly chilly northeastern winds dropped it back down to 17 C for the second half of the watch. Visibility from the platform was acceptable but not as good as usual. A noticeable, thick wall of whitish haze obscured the southeastern valley past about 10 km.

Raptor Observations:
All but one of the migrants passed by in the first three hours—before the wind changed to come from a more-northerly direction. Most came directly alongside and close to the Ridge, which allowed for very nice views of the Broad-winged Hawks, all of which were adults. A local Cooper's Hawk, with a full crop, was observed in the morning to circle up very high, drifting to the northwest over the west-side valley, but then it headed back southwest. After the weekend sighting of a Zone-tailed Hawk at Chatfield State Park (reported, with an accompanying photo, on CO Birds), every passing Turkey Vulture was regarded today with extra scrutiny, but all were determined to be the regular locals.

Non-raptor Observations:
Several swallows were seen flitting up and down the Ridge, often in small groups. Most of these were Tree Swallows but a couple of Violet-green Swallows were also spotted today. Quite a few unidentified songbirds, many of them likely warblers, moved north along the Ridge; one specific group looked and sounded a lot like Kinglets as they flew by. Also seen or heard were American Robin, Spotted Towhee, Woodhouse's Scrub-Jay, Western Meadowlark, Red-breasted Nuthatch, Blue-gray Gnatcatcher, Common Grackle, Black-capped Chickadee, Black-billed Magpie, White-throated Swifts, Common Raven, Northern Flicker, Mountain Chickadee, and Rock Wren. Seven Mule Deer were seen near Bare Slope in the morning.

Dinosaur Ridge - Bird Conservancy of the Rockies information may be found at: http://www.birdconservancy.org/
More information at hawkcount.org: [Site Profile] [Day Summary] [Month Summary]




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 Bird Conservancy of the
Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

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] Re: RFI -- crossbills and cone crops

Hi Stephen,

Thanks for your email. I don't have a well-defined protocol or standard for defining a good cone crop. I more or less think of good cone crops as something that you know when you see -- lots of small purple cones all over a tree, on most trees in a given area. Good ponderosa cone crops that I've worked on typically have a couple hundred to a thousand cones per tree. Good spruce and doug-fir crops often have 3-4 times that.

Put another way, you shouldn't have to work too hard to identify a good cone crop. Cone crops also tend to be quite similar across pretty long distances, so if on a casual hike you are noticing lots of developing cones on lots of trees, chances are the greater region is experiencing a good cone crop.

I hope that information is helpful.

Best,
Cody Porter

Hi all,

I'm here with my annual request for information on the whereabouts of good cone crops and crossbills.

Unfortunately, cone crops over much of the Rockies were non-existent or very poor this last year, causing a mass exodus of our usually abundant type 2 (ponderosa pine) crossbills to the Great Lakes and Northeast region (though it seems there have been several holdouts at feeders along the Front Range and even deeper in the mountains). Hopefully as summer progresses, good cone crops will develop and crossbills will return.

As usual, I am particularly interested in hearing about developing ponderosa pine, douglas-fir, and Engelmann/blue spruce cone crops. It is still too early to detect a developing spruce/fir cone crop, but developing ponderosa pine cones should be visible right now. Basically, look for lots of small purple cones on ponderosa branches (see attached photo for an example, taken on April 12 a few years ago). Come late June/early July, spruce and doug-fir will have similar small purple cones all over, if they are to have a good cone crop (attached is a not so great photo of that from July 6 two years ago).

Any information (even the absence of a good cone crop in an area) is greatly appreciated. The unpredictable nature of conifer cone crops and crossbills makes working on them an...interesting challenge, but the information you folks have given me over the past few years has made things go much more smoothly than I anticipated when I first started this project.

Good birding,

[cobirds] Bird Conservancy Banding Report - Chatfield Station, 4-30-18

Still slow, but getting a little more interesting!  Caught our FOS Yellow Warbler; I think this is the first time ever that we've caught one in April....our usual first date is May 5.  Also caught (and released unbanded as we don't do hummers) 2 hummingbirds - 1 Broad-tailed and 1 Black-chinned.  9 birds processed:

House Wren 5 (they are back in force; singing away)
Yellow Warbler 1
Spotted Towhee 1, banded 2016, recaught 2017.  A stunning male.
Song Sparrow 1

Come visit!  Station is open daily, weather permitting, through the end of May, except for May 10-12 and 28. We open nets about 6:30 and close around noon. If you would like to visit on a weekend, you must pre-register - go to the Audubon Society of Greater Denver website. Perhaps the best time for birders to visit is early in the morning during the week - fewer people and more birds! (School groups arrive each day between 9:30 and 10:30.)

[cobirds] Baby killdeer in April!

On 4/29, we saw 3 killdeer chicks feeding with their parents off Hygiene Road where people park to look north at the Bald Eagle nest (2 adults present).    Killdeer chicks are precocial, so may have been hatched that morning, but, man, seems early to me.  Northern Boulder County, for those scoring at home.

[cobirds] migrants, Larimer Co.

Wow, what a difference a few days make!  

After lamenting the paucity of spotted towhees and other birds in general throughout most of April, today's hike up Horsetooth Mountain was quite different.  Birds everywhere!  Including some early migrants.

Most unusual was a Western Tanager, a spanking bright male.  Also flagged by ebird was a Virginia's warbler (possibly 2).  Also new today were several blue-gray gnatcatchers. Full list from Ebird below.  Then, this afternoon at my feeders nearby, a male Lazuli Bunting showed up.

I guess the floodgates are now officially open!

[cobirds] Looking for barn swallow breeding sites

Happy Spring!

We are looking for sites where barn swallows are breeding in solitary pairs or in groups within and near Boulder County. We have been working on a variety of evolutionary and ecological questions using barn swallows as a model system within Boulder and around the world for over 20 years. Please read more about our work here: http://www.safran-lab.com/

If you own a structure that has breeding populations of barn swallows and would like to be a part of our study, please get in touch! 
Rebecca.Safran@colorado.edu.

Thanks so much!

[cobirds] Lazuli Bunting - Douglas

A lovely Lazuli started our morning -- first one of the spring for us. First one last year, April 24.
White-crowned, Chipping, & Song Sparrows. Gray-headed Juncos. Yesterday, eleven Pine Siskins. Today, wind.

Eastern Phoebe continues under the Colo 86 bridge, Walker Trail. The trail has had House Wrens for 3 days, but they haven't yet mounted the 200 feet elevation gain to our yard.

[cobirds] Sparrow I.D. - Pueblo

COBirders--  A few minutes ago while in my suburban-type back yard I saw a small sparrow that I couldn’t identify.  I didn’t have my bins and observed it for about a minute.  Very nearby, there was a Pine Siskin that I could use for size comparison. This sparrow seemed even smaller than the siskin (max. length 5”) and strikingly it carried its long tail very high, similar to a wren. The crown looked like that of a juvenile White-crowned; typical sparrow bill; no noticeable eye-ring or malar markings; back, dark with distinct medium brown and black markings; streaked breast though not heavily so; tail long, mostly brown. As the bird flew off it demonstrated an undulating pattern. It had been foraging in my raspberry patch which has rows of bare ground and newly sprouted plants in mulch.  Any thoughts will be appreciated.

[cobirds] Re: Glossy Ibis continues (Boulder Co.)



To all,
Yesterday evening Joe Hack and myself went to the pond to scope some of these birds, and we think we were able to identify both the hybrid and the glossy. Here is two pictures (phone through scope) of the bird that is (I think?) the glossy where you can see a dark face and iris.

Hi birders,

Friends Caleb Strand, Danny Montalvo and I relocated Ted Floyd's Glossy Ibis.  If you walk eastward along the trail north of Waneka Lake, there is a muddy pond on your left hand side with about 50 White-faced Ibis (not visible from the trail).  There is also a hybrid Glossy x White-faced Ibis mixed in with the other plegadis, so stay alert!  Pics of the hybrid will eventually be posted on eBird.

[cobirds] Wilson's Warbler Arrival - Centennial (Arapahoe)

This morning, I had a Wilson's Warbler in my Centennial, CO yard (Arapahoe). Also, two White-crowned Sparrows, perhaps lingerers from an earlier flock of six, and a Hermit Thrush. I also heard a House Wren, the first I've encountered in my yard in about a week.
