Visitors:
4 young hikers, 1 asked if I were bird watching, and I explained. His response was Very cool. Justin then an RT came within easy view, kiting, I was able to show them and told them that it was hunting and that it can see a mouse scampering on the ground from 100 feet up, which was surprising to them.

Weather:
Slight initial haziness over downtown Denver caused by wildfire smoke. The air to the South was grainy and hawks would disappear while watching them through my binoculars. Cool breeze starting with level 3 and becoming level 4 from the East. The air was very clear. There was minimum cloud cover 5% increasing to a maximum of only 25%. Visibility was 19 km to begin with because of the haze and went to 39 km by the 10 MST hour.

Raptor Observations:
About 30 ft before I got to the watch I saw an RT overhead. I kept watching it but when I got to the watch I couldn't see it against the perfectly blue sky, so not counted. One juvenile Swainson's Hawk with a light head and spotted lateral breast, which was originally seen over North Table Mountain, flew through the Kestrel Channel dropping into the trees of Lookout Mountain, wending its way gradually to the East and coming over the Eastern slope of the mountain to migrate. Non-migrant raptors: RT 7, TV 5.

Non-raptor Observations:
The first paraglider at 10:30 a.m. DST at no lift at all but the 4 which came after 11:00 a.m. had excellent lift. VGSW 1, MOCH 1, BTHU 1, WOSJ 8, STJA 11, CORA 1.

Predictions:
Sunny, with a high near 89. Southwest wind 5 to 8 mph becoming northeast in the afternoon.

[cobirds] Support the Dolores Dippers in the 2026 COBC

Hi folks,

For the past few years, our team has placed second or third in the annual Colorado Birding Challenge. We had a great time in Gilpin County in 2024 and we almost won it all in Clear Creek County last year. This year, we are pulling out all the stops.

In my opinion, Dolores County is the best county in Colorado. As a matter of objective fact, it is the most underappreciated county, at least when it comes to birding. Birders from the Front Range don't often visit, which might have something to do with the seven-hour drive, but all seven hours are worth it.

This year we are once again bringing back our signature gimmick. If you donate to the Dolores Dippers, you will get a bird named after you. (How this works: we take photos of the birds we see during the Challenge and name each one after a donor, e.g., "this one looks like a Kyle." Yes, you will get a photo.)


Good luck to all the teams who will be birding less beautiful and interesting counties on Saturday for the same worthy cause!

[cobirds] Bird Conservancy of the Rockies - Barr Lake Banding Report, 9/2/26

We came prepared for anything......Another 100+ Wilson's Warblers?  A whole bunch of the 120 from yesterday getting caught again?  Instead a relatively calm/welcome day, with "only" 44 new WIWAs and a total of 65 new birds.  We were especially surprised at the low number of recaptures - only 7 of the 120 from yesterday were caught again, suggesting that most had found sufficient food yesterday to move on last night.

So, today we enjoyed looking at the birds and sharing them with our visitors!  (Big days are both an adrenaline rush and give us hope......Wilson's must have had a very good breeding season......but it reduces the opportunity to focus on each individual lovely bird.)

Here's the breakdown of today's 65 new birds:

Western Wood-pewee 1
Traill's Flycatcher 1
Western Flycatcher 1
Red-breasted Nuthatch 4
Northern House Wren 5
Swainson's Thrush 1
Gray Catbird 2 (FOS)
Orange-crowned Warbler 1
MacGillivray's Warbler 2
Common Yellowthroat 1
Wilson's Warbler 44
Song Sparrow 2

We are open Tuesday through Saturday, weather permitting, through October 23.  Most weekday mornings there is a visitor session from 7:30 to 8:30, and on the weekends there are sessions at 8, 9 and 10 a.m.  Reservations are needed; here is the link.   Please join us......It is a great year to visit Barr!

[cobirds] COBC Upate

COBirders,
We now have 22 teams signed up for the COBC on Saturday who will be birding in 19 Colorado counties. This is a great effort and I am hoping that there are still a few of you on the sidelines waiting to jump on the field!

Participating in the COBC is easy and fun! Here's a quick step-by-step for getting started.
  1. Make the decision to join in the fun!
  2. Visit https://charity.pledgeit.org/2026COBC and click REGISTER
  3. Select the appropriate registration. For one of the four competitive categories, select team captain as either a CFO member or nonmember, or you can select Bird Your Own Way for our open category.
  4. Next, enter your species and fundraising goals -- no wrong answers here! -- and then scroll down to select one of the five categories and the county you will bird in and agree to the waiver, then click Add Ticket
  5. Then you'll be guided through the account setup process and you're done!
The five categories include four competitive options: The Challenge, The Green Challenge (no motorized travel), The Under-25 Challenge and new this year, The Big Sit (birding from a single location). There is also a non-competitive category, Bird Your Own Way that, like the name implies, has neither rules nor prizes :)

Every participant will select a team name and be assigned a Team Fundraiser Page. You can share the link to this page with your friends, family and on social media to receive support in the form of a one-time donation or a pledge for an amount for each species of bird you or your team identifies on Saturday.

As an added bonus, EVERY DONATION RECEIVED WILL BE DOUBLED until we reach $10,000 thanks to a very generous gift from a CFO member!

I hope you will decide to join us on Saturday for a fun birding adventure that will also benefit CFO's programs and conservation efforts plus generate useful eBird data detailing the status and distribution of birds in Colorado!

Good birding,

Peter Burke
CFO Board of Directors

[cobirds] How to report your COBC team's total species count

Hi everyone,

To report your COBC team's toal, please submit an eBird Trip Report to cobc@cobirds.org by 5PM on Sunday, Sept. 6.

I suggest creating the trip report in advance so you can use it to track your species total throughout the day.

To generate an eBird Trip Report:

1.  Log in to your eBird account and go to ebird.org/mytripreports.
2.  Select "Create Trip Report."
3.  Enter a name (e.g., "Washington Wallopers Official COBC Total for Washington County").
4.  Set the start date to September 5 at 12:00 AM and the end date to September 5 at 11:59 PM.
5.  Set the visibility to "Public" and click "Create Trip Report."

Every checklist you submit on Saturday will automatically populate this report. Please note that the checklists must be under the same account that creates the trip report. The simplest approach is to designate one person to handle all checklists and create the report. Alternatively, as long as checklists are shared and accepted by everyone on the team, anyone can create it.

If you haven't already, please share your team's fundraising page with your personal networks...family, friends, social media. CFO received a generous challenge grant that will match any donations you receive up to $10,000 this year! We still need about $3,000 in donations to maximize this gift, so your support is needed!

Best regards,
Peter Burke, CFO Board of Directors
