Female Harrier in Adult Male Plumage?

11 June 2014
This post is an interesting subject to explore. I was curious about an adult male Northern Harrier Peter Pyle published in Birding Jan/Feb 2014. He suggests that a male-plumaged specimen is actually an adult female in this caption: "...Although the specimen was labeled a male, it had a wing chord…
