Subject: Re: [cobirds] Status of Yellow-billed Loons in Colorado
All pertinent points made by David, and all used in my visit to Pueblo Lake
SP today where I observed Red-throated, Yellow-billed, and Common Loons.
Also, the Red-bellied WP is still present further downstream near the
Nature Center where I was able to help several others get on the bird along
the trail.
