Well, Suz on Sixth, who took the photo, has an update for us.
I thought that you may be interested to know that the dead pigeon is a) still dead, b) still outside of my window, and c) not at all pleased with the soaring temperatures — its feathers are all a-jumble! Of course, that could also be due to the exploding bacterial colony where its gut used to be and the oddly curious pigeon bretheren that visit, and preen, on occasion. But, I digress.
Efforts have been made to get the tenant across the shaftway to do something about the poor dead bird. But the tenant does nothing.
So how long before this pigeon decomposes?
Said tourist back in February: "Before full decomposition you will have three more Subway sandwich shops in your neighborhood."
