Since several people responded, I’ll now respond to whole group. Wendy Beers and I checked it out yesterday, prepared for potential rescue. The problem appears to be 3 patches of tar on its side/belly that it was spending all its time trying to remove, rolling over repeatedly to pick at it. I think the leg is fine (which I couldnt see the day before), and the bird is still very able to dive and quickly swim a couple hundred feet underwater. Thus, rescue would be mostly impossible. That said, it should be able to eat at the moment and is also pretty protected within the harbor (right next to Yacht Club yesterday). Animal Control did not return calls.
