I previously posted about how Crows (Ravens) are considered by Scientists as being just as intelligent as Primates like Chimps and other Mammals, particularly Dolphins.
Here's an intriguing video of one that can talk, sing, and even curse!
According to Wikipedia, the Raven and Crow are the same. However, some say there is a difference, as in this video:
I believe there is a difference. From the internet & I quote: "Ravens differ from crows in appearance by their larger bill, tail shape, flight pattern and by their large size. Ravens are as big as Red-tailed Hawks, and crows are about the size of pigeons. The raven is all black, has a 3.5-4 ft wingspan and is around 24-27 inches from head to tail."
