Vanilla NWN has two bird models c_a_bird_rap (raptor) and c_a_bird_rav (raven) that are used for hawks and ravens. The aesthetic issue is that the raven model is just a recolor of the raptor model, so the raven totem animal companion/familiar looks like a blue hawk.
I made an override model with an improved beak and recolor of the raven model that would be better suited for corvids.
