Perhaps of interest, I found an immature male Orchard Oriole in Buena Vista this afternoon, along the 'Peaks View Trail' in the grove of trees just SE of S Pleasant Ave, appx 200ft from the trail. This appears to be the 2nd eBird record for Chaffee, and one of only a few for the central mountains.
I've linked my eBird checklist here, which includes a low-quality photo that I will replace when I get the chance. http://ebird.org/ebird/view/checklist/S37297570
