After the puzzling success of yesterday's plane spotting post, we've returned to ask for some more help. Goth reader Stefan writes in:

Hi, At a little After 3:00pm, Sitting at my desk, I noticed something circling 1 Madison Avenue. It looks like a Falcon or a Hawk. Don't know if he was visiting or picking a home, but he was definately flying around up there and flew in for a landing. I mananged to get a few shots before he flew away.

So what, exactly, is this bird? Sort of looks like a stealth bomber to us-- but again, we're really not big experts on local fauna. A little help?
