Terrible photo, but can ID.
Moved on from the top of the lamp post to perch behind Africa in the Unisphere.
From other times that I've seen this hawk in this area, I believe it is a red-tailed hawk. I recorded it about a year ago perched on a roost in the Sheboygan Avenue Community Gardens. This picture was taken near there, along University Avenue and the new state office building construction site. The hawk flew over to the golf course when I continued east on the sidewalk.
The Red-tailed Hawk (Buteo jamaicensis) is a bird of prey, one of three species colloquially known in the United States as the "chickenhawk," though it rarely preys on standard sized chickens. It breeds throughout most of North America, from western Alaska and northern Canada to as far south as Panama and the West Indies, and is one of the most common buteos in North America. Red-tailed Hawks can acclimate to all the biomes within their range....
