Here is what I found:
jackdaw |ˈjakˌdô|
noun
a small, gray-headed crow that typically nests in tall buildings and chimneys, noted for its inquisitiveness.
[Genus Corvus, family Corvidae: two species, in particular the Eurasian C. monedula.]

I do know there's a difference between raven and crows - this invites more research. Thanks!
