[cobirds] Two species of loons at Cherry Creek SP, Arapahoe County

Today at 9 am there were 2 Yellow-billed Loons together, about 6 ft apart, diving near Pelican Pt.  Best views are from the nearby marina parking lot. At the other end of the lake near West Shores was a single Red-throated Loon, with a needle-like bill, upturned, and a very white face & neck. No Common Loons seen!

[cobirds] Boulder Sapsucker

Hi

Given the degree of plumage variability between the Red and Yellow-bellied Sapsucker and based on the photos there may not be a definitive answer to which sapsucker is represented in the photos, but I could be wrong as I have been many times in the past.

Cheers

Bob Righter

[cobirds] Re: Boulder Sapsucker ID help please (Boulder County)

Consensus is that this bird is a young female Yellow-billed Sapsucker. The white wing patch seems to be obscured by chest feathers in my photos. 

This morning she was back at the same pine tree as yesterday.  

Thanks to those who helped me with the ID!

Hi folks,

This morning I photographed a sapsucker at the Boulder Community Gardens. My tentative ID is that it's a Yellow-bellied Sapsucker, but it confuses me because it doesn't show white wing patches. I'd appreciate any ID suggestions. 

Photos are at https://ebird.org/checklist/S205728343.

I'm thinking that this bird is a young female, transitioning between juvenile and adult plumage. There's a red patch on the top of the head but a white throat patch. It's speckled overall, with a general dark appearance. It has faint yellow coloring to the belly. Maybe the white wing patches are actually covered by the wind-blown chest feathers. 

I saw the same bird exactly a week ago to the hour on the same tree. It puzzled me a week ago because I didn't see white wing patches then either.  A week ago, I didn't have my camera.

The habitat is north-central Boulder on the edge of a suburban housing development about 3/4 east of the foothills. 

Thanks,

Richard Trinkner

Re: [cobirds] Boulder Sapsucker ID help please (Boulder County)

In examining some of Jim Ward's photos of the same bird in the below checklist it does look like the top tip of the white wing patch is visible, with the rest of it covered up by a few side/flank feathers that are untucked covering over the wing. Also Jim had shared a back of camera view with a BoCo chat group that showed a bit more of a white wing patch. In your photos it looks like a similar thing is happening >> if you look at where primaries are, the primary/secondary coverts appear to be mostly covered by untucked side/flank feathers.

Good birding,

Richard,

I think this is most likely an immature female Yellow-bellied Sapsucker.  It looks like birds I see here in Maryland in the fall/winter.  I think an immature male would be showing at least a hint of red feathering coming in on the throat given the extent of red showing on this bird the top of its head.

[cobirds] Grand Junction/Grand Valley CBC - Western Screech-Owl Results

We had a successful census of Western Screech-Owls (WESOs) as part of the GJ CBC.  Seventeen calling routes were assessed in the pre-dawn.  Boxes where calling was either not attempted or where calling failed were checked during daylight hours by looking inside with a camera-on-a-pole.  Most early-morning observers reported owls more responsive than usual with a few of the owls already calling when a car reached a designated stop.  One lucky pair of owlers encountered 10 Western Screech-Owls and 5 Great-Horned-Owls on their route; 15 owls in just over two hours is a good morning!  Our total of 91 WESOs was right on our ten year average.

Thanks to the many volunteers who have helped maintain and keep track of our WESO population!

[cobirds] Williamson’s (?) Sapsucker

Could the immature sapsucker at Boulder Community Gardens be a female or immature Williamson's rather than a Red-naped Sapsucker?

That would explain the lack of a white wing patch!

[cobirds] John Martin Reservoir CBC

Birders, 

Fifteen observers found 107 bird species on the 23 edition of the John Martin Reservoir CBC. Weather was calm, though cool, and water was mostly open on the reservoir, and partly frozen on Lake Hasty Most of the snow had melted from the 1 to 2 feet of snow that fell in early November. 

I'm only going to list uncommon species requiring documentation, or count high counts (HC), although many other uncommon species were also found. 

Long-tailed Duck (1)

Pacific Loon (1)

Killdeer (21) HC

Dunlin (2) HC

Least Sandpiper (2)

Hermit Thrush (1)

Brown Thrasher (2) HC

Chestnut-collared Longspur

Chipping Sparrow (1) New to the Count, documented by photos.

Canyon Towhee (30) HC, found in many habitats including tall sunflower patches.

Green-tailed Towhee (1) New to the count, documented.

There were NO mountain birds this year, except for one Townsend's Solitaire.

Most of the lowland riparian woodlands on the west side of the reservoir have burned in recent years, drastically impacting birds in this habitat. A few pairs of Northern Cardinals remain.

The deep snow in November drove many sparrows and grassland species out of the region, including the Le Conte's Sparrow and it's habitat in marshes.

Finally, and sadly, the most conspicuous species on the reservoir, besides living Snow Geese, is dead and dying Snow geese, subjects of Avian Influenza. In calm water, they float on the surface. They are imbedded in forming ice, and washed up on shore. The number on the reservoir is currently in the hundreds, perhaps more. 

Thanks again to the dedicated birders that make this a very special count.

[cobirds] 50th Pueblo Reservoir CBC -- 14 December 2024 -- 130 species

[cobirds] Initial results of the 2024 Denver CBC

The Denver CBC was held yesterday, Saturday, December 14.

100 species were tallied at the compilation and an additional 2 Count Week birds were noted (Tundra Swan and Eared Grebe)

Everyone felt the birding was "slow" with low numbers of individuals for many species.  However we did note (at the compilation):

Five species of Goose

Long-tailed Duck in two locations (Marston Reservoir and South Platte Park Reservoir)

White-winged Scoter

Two American Goshawk

Three loon species (Common, Pacific & Yellow-billed)

FOUR owl species (Eastern Screech, Great Horned, Pygmy and Saw-Whet)

Five Ruby-crowned Kinglets

a singleton Golden-crowned Kinglet

Winter Wren (complete with photos and recordings, so not a Pacific)

Big misses (not all areas have reported, yet)

Wood Duck

Northern Pintail

Northern Harrier

Rough-legged Hawk

American Pipit

No Harris's, White-throated or Swamp Sparrows

Final notes:

Very few ducks

Very few White-crowned and American Tree Sparrows

Very few Townsend's Solitaires and American Robins

Are they all still north of us and still to come?

Thanks to all the participants this year!  And special thank you's to Laura Steadman for whipping up a great potluck on short notice, all my AMAZING Area Leaders without which the CBC could not happen.  And a thank you to State Parks for use of the Chatfield State Park multipurpose room for our compilation and potluck.

[cobirds] CO Raptor ID Game

Hi CO Birders,

With all this talk of Christmas Bird Counts and winter raptor surveys, I thought I'd share a reminder that a few years ago I created a "Concentration" style game that helps people learn Colorado raptors. It's a great way to help newer birders get better with their IDs, and give more experienced ones an opportunity to have some fun while testing themselves.

https://cliq.biz/raptors/

Hope it's helpful,

- Chris Petrizzo, Broomfield

Re: [cobirds] likely juvenile Hybrid Greater White fronted goose? Dodd reservoir

I agree that your description sounds more like a juvenile, but I wanted to speak to the questions around hybridization involving Greater White-fronted Geese. There are several species that GWFG hybridize with, the most common (though rare) we would find in Colorado are hybrids with Cackling or Canada. Typically I rely on using the eBird media search when researching hybrids, as the regular ebird Explore Species search will not take you to the species pages for hybrids. As you can see in the screenshot below, there are several crosses in the drop down menu.

Interestingly more than half of the confirmed ebird records for Greater White-fronted x Cackling Goose are from Colorado -- 179 out of 362. There was one reported at Dodd Reservoir not quite a week ago by Thomas Heinreich (in this checklist), in which that bird almost has a white cheek, but where white would be is just smudgy brown/dark gray. There are slightly fewer confirmed ebird records in Colorado for Greater White-fronted x Canada Goose -- 145 out of 952 (world wide). 

The other 2 GWFG hybrids we would potentially find in Colorado would be Snow x GWFG and Ross's x GWFG. However, there are only a dozen Snow x GWFG ebird reports in Colorado. There are only 2 total Ross's x GWFG records in eBird, one of which is in Colorado. Note these are observation counts and not necessarily individuals -- these are the truly rare birds!

In fact one of the coolest birds I've observed was a Snow x GWFG I observed in Southern Indiana. Check out the photos of it in this checklist: 

https://ebird.org/checklist/S124790038

Also, here is a checklist from when I observed a GWFG x Cackling Goose in Weld County: 

https://ebird.org/checklist/S101205369

Also, here are a couple of good resources I've found on hybrids:

Bird Hybrids of North America Facebook Group

Bird Hybrids Blog - Note it hasn't been updated in a few years, but has good write ups on most hybrids.

Thanks,

[cobirds] Hybrid Greater White fronted goose? Dodd reservoir

There's an odd looking greater white fronted goose, maybe a hybrid? S/he has the orange bill and orange (a little more faded than a usual GWFG) legs, white under tail, body color similar to GWFG, but no white on face and the goose just looks a little, well, different.

[cobirds] Free Lunch & Learn webinar open to all, on the Winter Raptor Survey Wednesday, December 11, 2024

Hi everyone.

Many of you may not know at there is a regular series of talks on Wednesdays once a month open to all, under the auspices of HMANA, on topics related to raptors.

This Wednesday,  a very pertinent talk on the Winter Raptor Survey  that anyone can sign up for, see below. If you're interested you can ask questions as well during the program.

You can also sign up to get emails from Julie Brown regarding future Lunch & Learn programs.

Previous talks are available on YouTube as well, if you search for "Lunch & Learn." You can find topics on raptor ID, raptor migration, etc.

I have seen most of them, either live,  or on recording, and have always come away knowing more.

December Lunch & Learn
Wednesday, December 11, 2024

12pm eastern 
We're looking forward to getting WINTERY this week! Vic Berardi, HMANA board member and chair of the Winter Raptor Survey committee will be joining us to talk about the Winter Raptor Survey program. He will discuss how to participate in this community science program, some of the raptors that you might see, and an update on the data that's been collected over the years. 

Vic Berardi is the founder of the all-volunteer Illinois Beach State Park Hawk Watch, which has conducted twenty-five seasons of full-time hawk migration monitoring since 2000. In 2013 he co-founded a new site at the Fort Sheridan Forest Preserve, also on the shore of Lake Michigan, in Highland Park, IL. Both of these sites contribute data to the study of raptors migrating along the western coast of Lake Michigan and through urban areas. Vic served as the Central Flyway Editor for Hawk Migration Studies for several years. In 2014 he was the recipient of HMANA's Appreciation Award for his outstanding service furthering hawk migration studies and conservation. In 2009 he was awarded the Service to Chicago Area Birders by the Chicago Audubon Society. In 2007 he was awarded the Grassroots Conservation Leadership Award for raptor education and research. Vic is also an accomplished photographer and regularly donates his photos to raptor conservation efforts. Many of his photographs have been on the covers of Hawk Migration Studies. He has also contributed to books by well-known raptor experts, including Brian Wheeler, Jerry Liguori, and Brian Sullivan. 

This program is FREE and open to all. Registration is required, please click the link below to register.
https://us02web.zoom.us/meeting/register/tZAvf-CvqD4jGNZqYKx7kZzW3V8dltb74Lqf

For those not able to join via Zoom, we will live stream the program on our HMANA Facebook page as well. Recordings of all programs will be available on our website, hawkmigration.org, following the event.

Hope to see you there!

This is our 3^rd season doing volunteer Winter Raptor Surveys (WRS) in Colorado for the Hawk Migration Association of North America (HMANA), since moving to Denver from Cornwall, Orange County, New York. We had done 8 seasons in NY,  along 4 different routes.

We conducted our 2^nd Winter Raptor Survey of this winter season yesterday, going from Bennett to Jackson Lake on an all-day trip along small dirt roads, mainly. This route was begun only in December 2023, and we did it 3 times in December 2023, and January and February 2024.

We had the best numbers and quality along this route this time, with a total of 69 raptors including:

Prairie Falcon 5

Merlin 6

Ferruginous Hawk 4

Golden Eagle 1 adult

Sharp-shinned Hawk 1

Northern Harrier 3

Bald Eagle 2

American Kestrel 34

Red-tailed Hawk 13

 

Our 1^st WRS of this season was in South and East Boulder a week ago. I did not post the results on COBirds as there was nothing special we saw. We did see 60 raptors:

FH (Ferruginous Hawk) 3

AK (American Kestrel) 18

RT (Red-tailed Hawk)  32

BE (Bald Eagle) 6

NH (Northern Harrier) 1

 

Anyone can do a Winter Raptor Survey (WRS) for HMANA, if you know of an area which has wintering raptors, and you have reasonable raptor ID skills. As you do it, your skills will improve.

https://www.hmana.org/winter-raptor-survey/  is the official website with plenty of information on how to conduct a survey. You can do as little as one survey a year in January, or go whole-hog as we do, doing a survey in December, January, and February; and we do 4 different routes – which means we do one a week for the 3 months.

If you need help creating one, you can always count on me to come with you and help set up a route.

Robert Beauchamp has had a WRS along the Nunn Raptor Alley since 2022 after I posted our results, and had encouraged raptor enthusiasts to start their own WRS. He did his 1^st WRs of the season, also yesterday, and you can read his report, as well as ours at https://wrs.hmana.org/public_html/index.php  where you can find reports of every WRS in the country on the main page.

If you want to find WRSs in other states, go to the left sidebar, and click on Survey Map, zoom in and click on the WRS you want.

This is a good way of finding raptors if you're interested in going and looking for them. If you don't have a WRS, you can only see the general area the raptors were seen. Since I have a WRS, I can see specific details of when, and where specifically, a particular raptor was seen on anyone's WRS.

Contact me if you have any questions.

[cobirds] Denver Christmas Bird Count (CBC)

One final plea for observers for the Denver CBC this upcoming Saturday, December 14.  Area names in red are areas that could use more eyes and ears (see list and map below).  Even if you cannot help with the Denver CBC due to date conflicts, PLEASE consider helping out on any CBC this season.  CBCs are fun and have provided wintering bird data for 124 years!  No matter your birding skill level, YOU can help!

For the Denver CBC, areas in red text (below) needed additional observers.  Area leaders in black text can ALWAYS use additional help.  Please consider lending your skills this season.

Denver CBC Compiler: Joey Kellner at SWDenverBirding at gmail.com

Contact me at the email above and I can send out contact information for the areas below.

Thank you!

[cobirds] Union Reservoir December 7th

Hi all,

Archer Silverman and I went up to Union Reservoir yesterday and found all of the reported birds to continue -  very cooperative Yellow-billed and Pacific Loons, one (possibly two!) Long-tailed Ducks, a female Barrow's Goldeneye, massive numbers of Common Mergansers and Cackling Geese (with a few Red-breasted Mergansers and Ross's Geese mixed in), and most notably a confiding Short-billed Gull. Wingtip photos were taken and an apparent lack of extensive black on the outer webs of p7 and p8 indicates that it is a genuine Short-billed with no suspicion of a Common Gull (pending review by Nick Komar, though). A very birdy and productive spot.
