As viewed from 5th and Los Angeles last Sunday evening:
That's not big pigeons on top of the Rosslyn Hotel sign, it's 3 chicks. As in girls. They climbed the sign and proceeded to pass the hooch between them.
The blond in the middle walked on the ledge of a 6 story building about a half hour prior. Me thinks she was a gymnast many years ago.
Other views from the evening in my flickr set.
p.s. i just checked out Angel's flickr pics and found a great one of the the little birdies, I mean girlies, on the sign.
