[cobirds] Short-eared Owl, Longmont, Weld/Boulder County

[Todd Deininger]

Driving home from work last night, 10/20, a Short-eared Owl just missed my 
windshield. It was flying west out of Weld County into Boulder County on County 
Line Rd just south of the St Vrain River, 40.151768,-105.055336.

[cobirds] Final vote Nashville 8, Orange Crowned 2

[kickback]

Eight responders think the bird in the original picture is a Nashville
warbler. Two lean towards Orange crowned but I don't think they lean
very strongly.

Main reasons in favor of Nashville

1. White vent with yellow coverts
2. Complete eye ring , no black loral line
3. Complete gray hood although demarcation between throat and hood
indistinct
4. Bill shape
5. Head shape

Several people think it is an immature female Nashville warbler..

Thanks for all of the comments

[cobirds] New Images Posted to Website - Bald Eagle, Common Loon, Gray Jay, Harlequin duck, kingfisher, meadowlark, Taiga Spruce Grouse, Willow Ptarmigan

[Ronald Green]

In the middle of August I traveled to Alaska for two weeks. During the first
week I stayed at my brother-in-law's cabin on an island in a small lake in
Two Lakes where I was able to observe and photograph a group of loons
(around 9), as well as a older baby. It was not uncommon for them to swim
within 5 feet of our floating pontoon. Other bird images were taken from
such places as Denali and travels along the road to Seward. Many of the bear
photographs, and some of the other animals, were taken in a wildlife
conservation area. Others such as the moose were all images taken from out
in the wild. I hope you enjoy the images. Your comments are welcome.

[cobirds] Blue-headed Vireo (Pueblo) 10/21

[Brandon K. Percival]

There was a Blue-headed Vireo seen just inside of the Pueblo Zoo from Pueblo 
City Park at first, and then only seen from inside the zoo, near the Bison 
exhibit.  Both Leon Bright and I were able to see the bird.  I was able to get 
numerous photos.  The bird was in a loose flock of birds, that included 
Yellow-rumped Warblers, as well as Pygmy and White-breasted Nuthatches, Brown 
Creepers, Mountain Chickadees, Ruby-crowned Kinglets, Bushtits, and Cedar 
Waxwings.  It seems like the flock of birds moves from Pueblo City Park into 
the Pueblo Zoo, where there is a lot of berries to feed on.

At Pueblo Reservoir eariler this morning, there were five Common Loons 
present.  Most of them were from West Fisherman's Point west to the State 
Wildlife Area old boat ramp.

Good birding,

Brandon Percival

Pueblo West, CO

[cobirds] Golden-crowned Sparrow---Red Rocks/Jeffco 10/21

[markchavez]

The Golden-crowned Sparrow was present again today with a White-throated 
Sparrow.  If you get up there try to bring some seed.  If we keep these feeders 
stocked you never know what will show this fall/winter.

[cobirds] golden-crowned sparrow discussion

[Dave Leatherman]

Golden-crowned Sparrows seem to be a recent source of amazement: we are 
somewhat amazed they're here at all (most of us), amazed they aren't building 
up a population (Suzi), amazed they are absent (Bob), and amazed they aren't 
documented (Brandon).  

My thoughts, at the distinct risk of oversimplifying things, would be they 
occur in small numbers in Colorado, probably every year, in migration 
(especially October).  Sort of like Varied Thrush.  A few probably find niches 
that allow them to overwinter.  Because they are cryptic, particularly when 
associating with large numbers of White-crowns (gambelii, etc.), and because 
their habits are also not conspicuous, about the only time we "get onto them" 
is at feeders like the one at Red Rocks.  I suspect if the birds at Red Rocks 
or Tunnel Drive were banded, we would find out it is the same individuals 
coming back year after year.  When a particular "regular" dies, there is a void 
of years until another one, during a solo off-course migration or association 
with species that normally pass thru and/or winter in Colorado, finds a 
particular niche of dry brush with abundant food (we birders may or may not 
know of), and stays.  They don't build up numbers probably because they don't 
breed here.  And they aren't documented because documenting with the official 
Colorado Bird Records Committee, as opposed to posting on COBIRDS or in The 
Journal (Colorado Birds, "News From The Field"), is more time-consuming (no 
excuse, just a fact).  Surely, Golden-crowned Sparrow has always been on the 
list of species for which the RC would like documentation.  Probably birds like 
the ones at Red Rocks and Tunnel Drive are seen by many people other than the 
original finders, and there is an assumption the finder will write it up.  I am 
among "the guilty majority" (sounds like a special interest group) who have not 
written up Golden-crowned Sparrows and many other rare birds, and personally 
plan to make a project out of getting somewhat caught up this winter.

[cobirds] Swamp Sparrows and Eared Grebes; Manitou Lake, Teller Co

[Jeff J Jones]

This morning, ~9:30am, there were two calling swamp sparrows in the marsh
beneath the dam at the ne corner of the lake. Got good looks at one.

 

Also present were two winter-plumaged eared grebes. Also a dipper below the
dam spillway. Otherwise the usuals.

[cobirds] Golden-crowned Sparrow Red Rocks

[picapica]

>From my records:
Single Golden-crowned Sparrow was seen on Red Rocks Christmas Bird Counts 
12/15/1990, 12/16/1995, 12/21/1996, 12/19/2009.
Addional records for Golden-crowned Sparrow at Red Rocks: 1/5/1991, 1/25/1992, 
2/14/1993, 4/16/1994, 11/19 and 12/10/1994, 1/21/1995, 12/15/1996, 1/7 and 
2/2/1997, 2/1/2010 and 10/17/2010. All were single individuals with the 
exception of 1/11/1997 when my notes show two individuals with the possibilty 
of 
a third.
I do not have records prior to 1990. Since I do at least two counts associated 
with the CBC, I believe it is possible that Golden-crowned Sparrows were absent 
from the Trading Post feeders in mid to late December beginning in 1998 through 
2008. For me their seeming absence is as much an enigma as is their presence.
