[cobirds] Re: Possible Yellow-billed Loon, Cherry Creek State Park

[David Tønnessen]

Hey Cole,

Echoing what Nick said, I would've expected a paler loon overall with a 
heftier bill rather than what looks like stark contrast between dark upper 
parts and pale below, features typical of Common Loon. While not entirely 
invalid, bill color isn't something I find especially helpful for ID of the 
two species in basic plumage at a distance, especially as I've seen Commons 
with yellow-looking bills whether as a result of lighting or just general 
variability. A combination of hefty bill and overall structure, stronger 
scale pattern in the back, and overall pale and low-contrast plumage from 
the top/back of the neck to the underparts I find to be most helpful in 
picking out Yellow-billed.


Good Birding!

Re: [cobirds] Sandhill Cranes flying southeast over east-central Denver (Denver County)

[Ray, Graham]

About 10 minutes ago approximately 100 Sandhill Cranes flew over Stapleton - 
generally in a southern direction.  I was shoveling the driveway and heard a 
strange sound - I thought I had mice or squirrels in the bushes.  Then I looked 
up and there they were!  So exciting!

[cobirds] A fun time along the Platte river, Arapahoe County

[Michael Robinson]

I observed a hugh flock of sandhills cranes flying south above the hogbacks 
near Chatfield reservoir at 11:45 AM on Monday, Oct 28.
Estimate at least 500 in three waves.  Appears this sighting has been reported 
earlier and just confirming my observation.

Re: [cobirds] Possible Yellow-billed Loon, Cherry Creek State Park

[Nicholas Komar]

Cole, in my opinion the bill is too small, not yellow enough and the head is 
too dark. However better photos could prove me wrong. 

Good birding,

[cobirds] Possible Yellow-billed Loon, Cherry Creek State Park

[Cole Sage]

I saw what I believe is a Yellow-billed Loon at Cherry Creek State Park
Lake loop.

Ebird checklist with photos:
https://ebird.org/checklist/S61011454

Ebird comments copied below:
Seen from lake loop and observation area by me and another birder (I am so
sorry but your name has slipped my mind). We both noticed that the bird
seemed to have an unusually yellow bill that seemed slightly upturned. On
closer examination I could find no black on the tip. Based on what I have
read all common loons should have a black tip(?). The bird was far away so
pics are cropped.

I have only seen one Yellow-billed Loon so please correct me if I am
wrong...

[cobirds] A fun time along the Platte river, Arapahoe County

[Brian Johnson]

I went to my usual patch along the South Platte River between Bowls and the 
begging of the Northern Wildlife Area. I found some rather nice and exiting 
patch first patch records for me. The first excitement was the large flock 
of *American Pipits *feeding in the river along the many river rocks, 
moving downstream and back up stream between the south end of Hudson 
Gardens and Reynodl's Landing Park. There was probably about 30 of them, 
but exact numbers where hard to come by with them flying all over the 
place. At the end of the walk I came across the most exciting first patch 
record, a lone *Sandhill Crane* circling over Cooley lake and gaining 
altitude quickly. It was by it's self, maybe separated from the main flock, 
and bugling constantly. I later saw a lot more cranes at Clement Park in 
Jefferson County, which gave me a more unobstructed view of the hogback. 
Along with the birds it was nice and cold, my preferred weather.
Good Birding,
Brian Johnson
