Grey Dove Griffon

As common a sit in cities as the regular pigeon or dove, the Grey Dove Griffon is a small relative of the griffon that is no bigger than a regular house cat. It is named for its plumage and the colour of its fur, as its front half resembles the pigeon. It thus can be mistaken for one if someone is not looking closely.
The Grey Dove Griffon is, sometimes, aggravatingly intelligent. They often out-compete the local crows and ravens. But some people have taken advantage of this, and Grey Dove Griffons are trained as couriers for messages, as they are more focused on the possibility of a reward at the destination than their smaller-brained cousins.
