I noticed this pine warbler when I got up from my desk and saw him resting on the ledge right in front of my window. My office is on the 16th floor, so I was obviously worried to see a pine warbler hanging out up here. Sometimes we'll see rock pigeons up here, but it's out of the ordinary to see a warbler.
Then I began to see the obvious signs of a bird in distress: open mouth, and flexed wings. There were points that the bird really worried me (like when it was laying face-first on the concrete, with its butt in the air) but then it stood up and when I looked away for a minute it flew away. Let's hope this pine warbler made it back to park safely! :-)
These pine warbler photos were taken with my cell phone, and are in order:
