I found this site: http://hint.fm/wind/ interesting because it visually
represents the winds terminating precisely in the area Brian described, at
least, I think so. I am assuming where the lines converge and get more
concentrated are the areas most likely to have the highest number of
birds
t; say the more likely one to have more birds is the northern circulation

rds. Here is a zoomed in map:

You can already see reflections of these circulations in the current
surface observations:

While riding my bike in some drizzly weather I heard a couple of Red
Crossbills flying over old town Fort Collins.
Another wave of Wilson's Warblers were back in a box elder tree I have at
home numbering in the high teens, about 16 individual birds feasting on
some type of leaf hopper insect.
In answer to Bryan’s request for reports from the field, visits to several
locations in Fort Collins/Wellington area of north-central Colorado (eastern
Larimer County) both yesterday and today suggest that there was very little
turnover in birds present. Most of the birding both mornings was at
I believe the photos show a Brown-crested Flycatcher of the western
large-billed subspecies. I joined Brad and Dave Wade this morning in an attempt
to relocate this rare vagrant from south Arizona/NW Mexico(!) at the Cobb Lake
SWA, a 1-sq-mile property just north of Cobb Lake, southeast of Welli
The much ballyhooed fallout of passerines appears to have fallen elsewhere. At
least Bear Creek Park, Marston Reservoir and Chatfield State Park bird
populations appeared relatively unchanged this morning.
The saving grace, however, was the appearance of three species of water/shore
birds at
Each morning I walk a 2 mile loop down from our vacation home in Estes Park to
buy the daily newspaper. On this morning's walk I encountered what I can only
describe as a wave of Yellow-rumped Warblers moving through at about 8:00. My
conservative count was 30 birds in 3 minutes, and that was ju
We decided to believe the weather report that we saw when we went to bed
Wed night, so 3 volunteers, 2 other staff and I headed out to the banding
station for a 6:30 opening, despite the overcast sky and threat of rain.
We waited around for about an hour, anticipating/hoping for some clearing.
COBirders,
Yesterday and today a strange-looking dove came to my cracked-corn feeder.
It seems to be either an intergrade of White-winged with (?) or a WWDO with
melanistic attributes. I have posted three images on my Flickr page,

Hello, Birders.
My experiences in Lafayette, eastern Boulder County, today, Thursday, Sept.
11, were more or less aligned with those reported by others. Basically, the
birds around my local patch, Greenlee Preserve, seemed about the same as in
recent days, with Orange-crowned and especially Wil
We found most of the usual birds until we hit the long straight section
through the rabbit brush. Here we spent most of our two hour outing sorting
through a large and varied flock of birds.

COBirders,
Multiple people went birding today on my word. Multiple people didn't see
a change in fortune from previous days. But others did. What happened?
You may remember what the computer model output looked like showing two
distinct areas of convergence and circulation.
