Apologies for poor photo. This Common Raven was seen raiding a Pigeon nest on the brick ledge of an adjacent condo building (at approx 14th floor)…flew away with live Pigeon hatchling (in beak). Same Raven returned for 2 additional Pigeon meals. Quite a dramatic sight while enjoying my own breakfast. The overall size of bird, heavy black bill and deep vocalizations all clearly indicated a Raven.
