Jukka Jantunen has a big collection of Red-tailed Hawk photos on his Flickr account. His collection is really cool because it shows huge diversity in Red-tailed Hawks plumage-wise in the Yukon. These hawks seem to be impossibly diverse with their plumage; some individuals can look like a totally different species. I’ve attached the link to his Flickr collection here. If you have any interest in Red-tailed Hawks (and even if you don’t) his collection is educational and interesting. Feel free to check it out!
