It's in Known by its Song, when Raven shows Weiss and Yang that she can transform into a bird. While she's flying around in bird form, Weiss specifically calls it a raven, and Yang says that she has seen that bird before. The bird then flies toward them through the trees and is suddenly replaced with Raven. In the next episode, Rest and Resolutions, while they're in the living room after Ozpin explained things off-screen, Weiss states that she and Yang literally saw Raven "change" right in front of them, indicating that the raven Weiss pointed out really was Raven Branwen.

As for whether or not there's a difference between crows and ravens... it depends on who you ask. For some, the difference is:

Raven:


 * Larger than a crow


 * Diamond-shaped tail


 * Beak is slightly curved with the feathers extending onto it


 * Shaggy neck feathers


 * Its call is a deeper, raspy croak

Crow:


 * Smaller than a raven


 * Fan-shaped tail


 * Beak is straight


 * Smooth neck feathers


 * Its call is a short "caw"
