[cobirds] Chico Basin Ranch Banding Report, May 30, 2026

All spring we have not caught much quantity but we have been fortunate that we have caught some quality birds. Today was no exception and of course the highlight bird decided to be caught the last net check. What a surprise when I saw there was a female Painted Bunting that came out of the net. I was not the person who extracted it so I only saw it when it came out of the transport bag to be banded. I could not believe it but nothing else looks that color green of a female Painted Bunting. 

A couple Swainson's Thrushes, Wilson's Warbler, and three female Orchard Orioles were the most identified migrants of the day. The Northern Parula was still singing near the goats this morning as well as the Red-headed Woodpecker came and went a couple times near the banding station during the morning.

13 New Banded Birds

Wilson's Warbler- 1

American Goldfinch- 1

Lazuli Bunting- 1

Painted Bunting- 1

House Finch- 1

Blue Grosbeak- 1

Orchard Oriole- 3

Ash-throated Flycatcher- 1

Canyon Towhee- 1

Swainson's Thrush- 2

1 Recapture

Bullock's Oriole

1 Return- banded as an adult in 2025

Blue Grosbeak- She is at least 4 Years old 

The banding station will be closed tomorrow but will reopen Monday at sunrise until @11AM. 

If wanting to bird/visit the ranch tomorrow or next week, please register on the Aiken Audubon Website www.aikenaudubon.com

Have a good weekend and see you Monday!

Western Wood-pewee 3
Western Flycatcher 3
Least Flycatcher 1
Warbling Vireo, Western by measurements 1

Swainson's Thrush 1
Gray Catbird 1
Yellow Warbler 2

Two more days!

[cobirds] Re: Magnolia Warbler, CSR , El Paso Co, Thursday

I just want to agree with Diane that your posts and your banding have been great to read about. Candice and Tim Johnson

Hey COBirders,

I, too, tried banding in the drizzle Wednesday at Clear Spring Ranch - hoping for some sort of fallout, but it remained pretty quiet - and only 12 birds were  banded.

Today the site was sloppy wet, but there were more birds, both migrants and local nesters.

Highlight was a SY M Magnolia Warbler - my second this season. Very petite, very cute.

Also larger birds were banded today - for a total of 26 today - my best day this week. 750 for the season.

Including:

Blue Grosbeak, 4 (2 Ad M, 1 SY M, 1 Ad F) - BLGR’s just arrived this week.

W Tanager, Ad F

Bullock’s Oriole - Ad M

Swainson’s Thrush, Ad

Black-headed Grosbeak, Ad F

Brown Thrasher - SY (second year)

Lazuli Bunting, Ad F

Western Wood Pewee, 2 Ad, along with two yesterday - they just arrived Tuesday!

MacGillivray’s Warbler 2, SY F’s

and 3 Yellow Warblers, 1 Ad M, 2 SY F’s.

Friday is my last day at CSR banding…. really. It is getting to be too much for my aged knees, so I am letting it go.

Many thanks to those who shared supportive messages over the last 15 seasons. It has been way too much fun.

Last I looked I had banded about 33,000 birds at Clear Spring Ranch since 2012.  Lotsa Chipping Sparrows!!!

Thanks, and Happy Migration!

[cobirds] Re: Myers Gulch Tour coming up Saturday

My spelling is bad:  it's Meyer's Gulch \ Walker Ranch Trail. (Thanks Paula).     Note:  this is filling up pretty fast.  Will need responses to individual email, before 8 p.m.  Friday.  

Happy birding, 

John T

All:

        Another free birding and nature tour coming up this Saturday May 30th, at Myers Gulch County Open Space, west of Boulder.  

We will hike a portion of the Myers Gulch Trail to see foothills birds and identify edible, medicinal, and poisonous plants and wildflowers.  Expect to see green tailed towhees, vesper sparrows, bluebirds, violet green swallows, raptors, ravens, tanagers, and other mountain birds, as well as butterflies and pollinators. This area is "mammal rich" with coyotes, mule deer, fox, pocket gophers, and the occasional moose and black bear.  

Limit to 12 people.  Do NOT respond to this group email.  Rather - response to me directly if you want to be on this tour.   I will respond with times and meeting place, and what to expect.  

Thanks, 

John T (Tumasonis)
