[cobirds] Re: Northern Shrike, Boulder County

Paula, my backyard in Broomfield is part of the anecdotal evidence to which Peter refers. We've had a Northern Shrike hunting around the Lac Amora Open Space for the last few weeks, and I got some really cool photos of it with a male House Finch in its bill. I posted one of the pictures on my Instagram feed for Broomfield Widlife: https://www.instagram.com/p/B6vEZczjfeA/

I also have photos of that same shrike chasing a Blue Jay, and eating a cricket!

—On Dec 29 a Rusty Blackbird was reported at Bear Creek Lake Park. First reported Dec 23 by Robert Raker.

LARIMER COUNTY:

—On Dec 30 two Yellow-bellied Sapsuckers were reported in Fort Collins at Grandview Cemetery. One is a young male and has been reported south of the Trolley House several times in different trees. Last reported by Dave Leatherman "in a medium-sized deciduous tree due south of the Trolley House out on City Park Nine golf course. This tree has a white tag on the north side about 7 feet up that identifies it as a tree I've never heard of called "Pacific Sunset Maple". This is a hybrid between Acer platanoides (Norway maple, a widely planted native of Europe) and A. truncatum (Shantung maple, native to northern China). The tag also says it is the horticultural variety called "Warrenred".

The Trolley House is the westernmost building on the south side of Mountain Avenue just east of the cemetery entrance. There is an east-west row of 10 or so Scots Pines that runs from the sw corner of the building w toward the golf course. It seems the bird spends a lot of time in those pines and retreats out into deciduous trees on the golf course (between the Trolley House and the softball fields to the south). This young male was first reported by Dave Leatherman on Dec 23.

The other Yellow-bellied Sapsucker is an adult that favors Austrian pines just east of the gray portapotty midway along the southern cemetery boundary road and often retreats to the big cottonwood just east of the pines. This adult male is probably the same bird reported by Fawn Simmons on FC CBC, Dec 14 and seen periodically in the cemetery since mid November.

—On Dec 26 a Gyrfalcon was observed near the Larimer County Landfill in SW Fort Collins. First reported by Robert Beauchamp on Nov 3. This is the same location a Gyrfalcon spent much of last winter. Please post updates to COBirds.

MESA COUNTY:

—On Dec 30 a Dunlin was reported at Horsethief Canyon State Wildlife Area on the shoreline of a gravel bar on the Colorado River. First reported Dec 28 by Douglas Diekman.

—On Dec 29 a Golden-crowned Sparrow was reported at Grand Junction Wildlife Area. First reported on Dec 28 by Mike Henwood.

—On Dec 27 a Wilson's Warbler was reported at Grand Junction Wildlife Area, in willows along the Colorado River, by Mike Henwood.

PUEBLO COUNTY:

—On Dec 30 a juvenile "kumlien's" Iceland Gull was reported at Pueblo Reservoir on the Sandspit at the boat ramp at South Shore Marina by Brandon Percival. Although it's no longer recognized as its own species by the AOU, and has been combined with Thayer's Gull, it is rare in CO.

—A Great Black-backed Gull that has spent the last umpteen winters at Lake Pueblo (nicknamed "Murray") is here again. See COBirds for most recent sighting (Dec. 30)

It's Christmas Bird Count time across Colorado, between Dec 14 & Jan 5.

[cobirds] Grandview Cemetery on 30December2019

First off, the two Yellow-bellied Sapsuckers sought by many of late continue in the Grandview Cemetery area.

I first heard (pecking), then saw, the young male this morning about 11:30am in a medium-sized deciduous tree due south of the Trolley House out on City Park Nine golf course. This tree has a white tag on the north side about 7 feet up that identifies it as a tree I've never heard of called "Pacific Sunset Maple". This is a hybrid between Acer platanoides (Norway maple, a widely planted native of Europe) and A. truncatum (Shantung maple, native to northern China). The tag also says it is the horticultural variety called "Warrenred". I got a few photos of the sapsucker from a distance before the activity of Fox Squirrels chased the bird off and I could never find it again. The squirrels are after sap oozing from natural cracks in the bark and twigs, and from sap wells made this morning by the sapsucker. [There is some very interesting literature, mostly by famous ecologist Paul Ehrlich and students, about all the creatures that poach sap made available by sapsuckers (making sapsuckers a "keystone species"). This work was done at Gothic, CO using motion detection cameras and direct observation. Among the visitors were butterflies and bobcats, and Ehrlich's camp made the suggestion that spring hummingbird migration might well be timed to follow right behind sapsucker movements to allow the hummingbirds to plug into sapsucker-provided fuel stations at a time of year when plant blooms and other food sources are scarce.] The photo below shows a couple features that prove beyond a doubt there are two sapsuckers operating in the periphery of the cemetery. The black lower throat is not solid on this bird, nor is the red on the crown and the chin. I checked good photos provided by Joshua Smith (December 27 eBird checklist) and Adrian Lakin (today's eBird checklist) of the bird operating about midway along the south edge of the cemetery and out onto the golf course, which show solid red crown and chin, and solid black lower throat. Case closed.

Also below, see a Fox Squirrel lapping dilute maple syrup from a natural branch crack in the Pacific Sunset Maple shortly after the sapsucker disappeared.

My guess is both the young male sapsucker and the squirrels will be back in the Pacific Sunset Maple at some point tomorrow, which is supposed to be in the mid-40s for a high and there should be good sap rise from all the recent snow.

The adult male sapsucker favors Austrian pines just east of the gray portapotty midway along the southern cemetery boundary road and often retreats to the big cottonwood just east of the pines.

[cobirds] 8 Greater White-Fronted Geese on Timnath neighboorhood lake

The lake is located on Twin Bridge Road and is near Bethke Elementary School. There is a trail around the lake, and there is parking available on the shoulder of the road. The lake is small enough that you could probably see everything from the car.

They were sensitive to human presence, but they still cooperated for some great photos (Macaulay assets)

[cobirds] Gyr not observed - am 12/30 - Larimer

No luck this morning on Trilby. Did see a Ferriginous Hawk and a nice light-morph Rough-legged Hawk.

Also, note to the other birder who's was there early, and left for work - you left your coffee mug on the fence, near the base of pole 16.

Good Birding,

[cobirds] Goose hybrid at Belmar Park, Jefferson?

Hi everyone,

I was out at Belmar Park yesterday afternoon when I spotted this goose among a group of Cackling Geese. These are the best shots I could get: unfortunately he never lifted his head while I was present. You can still make out black on his crown, the white cheek bordered by a little black, and the stark white neck speckled in spots by more black. My best guess is this might be a Cackling x Ross's or Cackling x Snow hybrid, but I wonder if anyone else has any other/better ideas?

Thanks!

Max Miller, Denver

LARIMER COUNTY:

—On Dec 27 two Yellow-bellied Sapsuckers were reported in Fort Collins at Grandview Cemetery by Dave Leatherman. One appears to be a young male and was last observed in an ash just south of the Trolley House. The Trolley House is the westernmost building on the south side of Mountain Avenue just east of the cemetery entrance. There is an east-west row of 10 or so Scots Pines that runs from the sw corner of the building w toward the golf course. It seems the bird spends a lot of time in those pines and retreats out into deciduous trees on the golf course (between the Trolley House and the softball fields to the south). Today the bird flew out of the pines into the ash, where it stayed motionless in one spot in the upper crown just soaking up the sun. This bird was first reported by Dave Leatherman on Dec 23.

The other Yellow-bellied Sapsucker was a male observed midway along the south edge of the cemetery in an elm. It was seen by Joshua Smith at approx. the same time Dave Leatherman saw the other one, hence we are now confident there are currently 2 different Yellow-bellied Sapsucker's at Grandview Cemetery. This male bird is probably the same adult male reported by Fawn Simmons on FC CBC, Dec 14 and seen periodically in the cemetery since mid November.

LOGAN COUNTY:

—On Dec 23 a SNOWY OWL was reported at North Sterling State Park by CO Parks & Wildlife. There was a SNOWY OWL found in the same park by Kathy Mihm Dunning in 2011. Pictures indicate the current owl sighting appears to be near the same location as the one in 2011.

[cobirds] Loveland birding (Larimer)

Today I scouted for the upcoming Loveland CBC which will be held Wed, Jan 1, 2020.

Highlights included:
3 Red-breasted Mergansers at Horseshoe Lake

1 Marsh Wren at Thompson School District Bldg

Dry Creek Reservoir (no ice) hosted a good variety of waterfowl and gulls including Thayer's and Lesser Black-backed Gulls.

A female Great-tailed Grackle joined the Blackbird roost just west of Cattail Pond at dusk.

I could not relocate Gyrfalcon or Bohemian Waxwings.

Re: [cobirds] Northern Shrike, Boulder County

What a thrilling thing to see!

I know this is totally anecdotal, but it's seems like I'm hearing more and more about shrikes hunting in suburban yards. Maybe in 10 years they'll be here in town all the time, just like the Cooper's Hawks have converged around the buffet stations in the suburban forests.

[cobirds] Aurora Res (Arapahoe) Loons

Greetings All

The photo of a loon identified as a Pacific at Aurora Res earlier this week looked likely to be a photo of a RT Loon.

So, I went out to look today and found 4 Common Loons and a YB Loon. I assumed the YB Loon to be the same as seen there early in December. The earlier bird was enormous, even in comparison to a COLO and had little or no "ear spot". Today's bird was marginally larger than nearby COLO and had a moderately prominent ear spot. Both had nice fringing to back feathers, so bird in both sightings was a youngster

Otherwise, nothing markedly rare a Aurora Reservoir. 5 Lesser BB Gulls and 5 Thayer's Gulls were nice, but no Glaucous Gulls or other less common gulls.

Good Birding

[cobirds] Northern Shrike, Boulder County

Wow! I just walked outside and instantly heard the screams of a small bird in one of my spruce trees. I walked up to the tree expecting to see one of my Cooper's Hawks, but a Northern Shrike burst out of the tree clutching a House Finch within inches of my face! I could still hear the poor finch screaming 1 1/2 blocks away.

[cobirds] Brant still present at Lake Arbor

The Brant was observed around 1:00 pm while scoping from the south shoreline of Lake Arbor and scanning to the west. When I relocated to the picnic pavilion on the west shoreline in an attempt to get a better view and perhaps a digiscope photo, I lost it in the mass of hundreds of milling white-cheeked geese.
