Here is a photo of a Great Blue Heron in breeding plumage. Notice the blue lore in front of the eye.
I photographed this other Great Blue Heron on Captiva Island today. It was standing on the rail of a deck at a restaurant and seemed oblivious to the patrons. Notice the blue tone on the lore and upper bill. Great Blues are magnificent birds.
