Autumn Nature in Rocky Mountain National Park

I miss visiting Rocky Mountain National Park nearly every week when I was working part-time in Boulder, Colorado. For the last several weeks I have been spending time a lot of time going through my image catalogs looking for bird images that I can add to My eBird checklists. I am about half way through 14 years of images. So far I found images of 375 species of birds in 46 countries, territories, and dependencies. One of the great things about My eBird is it helps me identify bird images by comparison with images in their collection, and by what birds would be common (or rare) for the locations where I took the images.
