.JUST as they ignore the pigeons that make up so much of their city’s meager wildlife, passers-by paid little attention to the curious scene on 29th Street and Ninth Avenue one brisk morning in December.
Jennifer Dudley of New York City Pigeon Rescue Central brought a bird to be X-rayed by Karen Heidgerd last month.
Jennifer Dudley, 44, a strawberry-blond opera singer, studied the corner of a mail distribution center entrance. A rumpled pink bathroom towel stained with bird feces lay on the ground. Nearby were a splay of cracker bits and the bottom half of a crudely cut plastic cup.
“They probably told him to shoo,” Ms. Dudley said, hypothesizing that building security had ushered the wounded pigeon from its resting place.
Another clue: “This should be green,” she added, standing above a mound of dark excrement a few steps away. “He’s definitely sick, but not starving to death.”
