Bird Photographs on Flickr

I wrote earlier about my discovery of Flickr as a great source for bird photographs. As I have continued to explore Flickr, I have become more and more impressed with this resource. Flickr sorts photographs by Groups. Here I list bird groups with 1000 or more photos or 100 or more members:
