The Rock Dove

Okay, this particular little bit of info goes specifically to my friends Mike, Rob and Lynn who were all at OVC on Sunday. Mike had asked what the difference is between pigeons and doves, and we all assured him that there was none.
The Pirate had come freshly from Barnes & Noble and had bought the "National Audobon Society Field Guide to North American Birds: Western Region" which has color photographs of all the birds listed.
Careful perusal of its color plates shows that the bird that everyone here calls a "pigeon," you know - that grey-bodied bird with the oil-slicked head, is in fact a "rock dove."
So, now you know.
