I worry that your article will leave people with a bad impression of the raven.
I have lived in Lancaster for 18 years. For the same amount of time I have been fascinated with the wildlife of the area. I can honestly say that the tortoise and raven are not the only species that are suffering because of man's greed and compulsion to build.
The ravens are exceptional birds. They have been cursed with an undeserved reputation of being outlaws. They are accused of being bloodthirsty carnivores. They have been feared as a bird of ill omen, fabled to forebode death, and to bring infection and bad luck. All of these tales are untrue. Quite the opposite has been proven by science.
They can grow to be over 2 feet long, and because they are aggressive bold and curious, they can be frightening. They are friendly, but they prefer to avoid man--their only predator. They have been forced to live with us, however, as we take over more and more of their territory.
