I would just like to point out that there are some stringent standards which are applied to breeding records. Please refer to the definitions of breeding codes in the Colorado Breeding Bird Atlas Manual:
Scroll down to the bottom for the definitions for each breeding code.
Two singing males on subsequent days in appropriate habitat, especially if they were counter singing, would garner at most a 'T'= Territorial= Probable. The presence of juvenile birds capable of sustained locomotion does not constitute a confirmed breeding record since they are capable of moving into the area from somewhere else. Without more direct evidence, we can only speculate on the origin of juveniles (south-bound migrants, molt migrants, locally produced, etc.).

Dave's photos prove three things, in my humble opinion:
1) Sparrows can be really difficult to identify,
2) a picture can say a thousand words,
And 3) two fresh-plumaged juvenile Baird's Sparrows were out there this morning.
I think these photos, in concert with other observations and evidence, demonstrate the first know successful breeding of Baird's Sparrow in Colorado. Congrats, Dave.

Greetings,
I've posted some of the photos from this morning on my Flickr site. There are 12 pics in all so instead of listing each individually, I connected with my home page. To view them, click on any photo, then use the arrow keys or mouse click the margins to move through them.
