Very few people have seen a falcon. While eagles have made a comeback since the '60s and the alleged DDT problems with raptor eggs (I said alleged, okay?), falcons are still relatively rare, where early in the 1960s they were very common. So, when my mother sent me a picture of a falcon nesting in a tree, I was immediately interested and clicked the link.
Mom said "I’ve received many remarkable nature photographs over the years but this photo of a nesting Falcon is perhaps the most remarkable Nature shot that I’ve ever seen. I hope you enjoy it as much as I did. Nature is truly breath-taking!
I've sent this to most of my older friends. The younger ones probably have never seen a falcon and wouldn't recognize it.
