I Know Why The Caged Bird Sweats

Lenox at Bedford, and Lenox tween Rogers and Bedford. Bird cages. With birds. What gives?

Birds Cooking In the Sun? Or Just Enjoying A Day Out On the Town?

I don't know nothin' about birds, but beyond the curious imagery of the street art, is there a reason why one might not want the birds to bask in the hot sun for too long? Granted the temp outside is probably in the safe zone. But like Tantalus, I wonder if this isn't a Big Tease to these animals.

I'm trusting, perhaps foolishly, that this is but a brief exhibition. Anybody know?
