This morning, while at a new trailhead facility along the north side of 
Piscataway Creek, a heard a nearby singing Prothonatary Warbler.  I 
spished a bit, and the warbler flew inside the trail kiosk (where I was) 
and landed on one of the crossbeams for the small roof. We looked at each 
other for a bit, and then it looked like the warbler was going to leave.  
I greedily spished one more time so I could continue looking at this 
brilliant bird at close range, when it flew directly at me.  It hit me 
forcefully on the elbow (forceful for a 16 gram bird that is), glanced off 
and flew into a nearby tree. It fussed at me for a few more seconds, than 
resumed singing, apparently content that its territorial rights had been 
preserved.
