We've got a raven.

[camwyn]

One sighting is a transient visitor, two sightings is a possible coincidence (even if the second sighting involves two birds), a third sighting that begins with hearing CROAK CROAK and looking out my window in time to see a big black bird flying away is a raven having taken up in the area.

We've had crows before, mostly just standard American crows but possibly one or two fish crows. The raven's new, though.
