[cobirds] Contact Info for Mike Carter, CBO founder & early director

Hi. I'm trying to get in contact with Mike Carter, the founder of Colorado Bird Observatory (now Bird Conservancy of the Rockies) regarding collaboration between CBO and banders at the Lykins Gulch/Allegra Collister Nature Preserve banding station in the early 1990s.  

If anyone has current contact information for Mike, I would appreciate it if you could pass my message along or let me know how to contact Mike.  I was given an @pljv.org email but a message to that email bounced. 

If you write me back, please don't reply all to the whole group. I wouldn't want Mike's information shared with everybody on this list. 

Thank you,
Megan

[cobirds] Chico Basin Ranch Banding Report, June 3, 2026-Bird Conservancy of the Rockies

Since it is the tail end of bird migration, I am not expecting any numbers. There has been some migrants still coming through. Northern Parula was singing when putting the nets up today. A Magnolia and Prothonotary Warbler were observed and photographed by birders at Headquarters little pond this morning. The nets are still catching Swainson's Thrushes. What will tomorrow look like? Hopefully, we can reach double digits.

Swainson's Thrush- 2

Orchard Oriole- 1

Bullock's Oriole- 1

Blue Grosbeak- 1

American Robin- 1

4 Breeding Bird Recaptures

The banding station will be open tomorrow through Saturday from sunrise until @ 11AM.

Any ideas? It clearly has a black stripe around the neck.

[cobirds] Inaccessible birding opportunity at Antero Reservoir in Park County

Antero is now closed to general access as it is being de-watered to move the water supply to a downstream reservoir with less evaporation. I viewed it with a scope today from at least two miles away at Buffalo Creek Reservoir. It is perhaps 50% de-watered now, and the South Fork of the South Platte is flooding its banks downstream of the reservoir with the discharge of water. Due to the distance and heat shimmer it was hard to be sure of any IDs except for Am. White Pelicans, apparent cormorants and generic flying gulls (no doubt most or nearly all California Gulls). There were thousands of birds there! Blurry blobs in the scope, and no doubt many little ones I could not discern at all. I estimated about 600-700 pelicans, and maybe 2000 gulls, and lots and lots of other birds, too. There are huge expanses of shallowing water and mud flats, and presumably many fish and other life available for the birds. It would be awesome to get in there to see what is there!  I'm wondering if the Snowy Plovers that breed there are able to nest this year with these changes. I hope so. But scads of other birds are reaping the bounty for now. 

The rookery at Eleven Mile Reservoir (California Gulls, Am. White Pelicans and Double-crested Cormorants) is going strong. Birds nesting there fly to Spinney Mountain Reservoir and Antero to forage.

[cobirds] Chico Basin Ranch Banding Report, June 1, 2026-Bird Conservancy of the Rockies

Happy June! Migration is winding down; but there are still some flycatchers, Lincoln's Sparrows, and Swainson's Thrushes that are trickling through. All recaptures were breeding birds and maintained or lost a little weight from banding time. Breeding birds will be burning the energy they eat during nesting season.

12 New Banded Birds

Common Yellowthroat- 1

Western Wood-Pewee- 1

Willow Flycatcher-1

Alder Flycatcher- 1

Northern House Wren- 1

House Finch- 2

Lincoln's Sparrow- 1

Swainson's Thrush- 2

Northern Mockingbird- 1

Bullock's Oriole- 1

5 Recaptures

Western Wood-pewee- 1

Bullock's Oriole- 4

The Banding Station will be open tomorrow through Saturday from Sunrise until @ 11AM. Please register on the Aiken Audubon website if interested in visiting the ranch. www.aikenaudubon.com

Enjoy the Day,
