It looks like Tompkins Square Park lost an eyass sometime in the last few days. Laura Goggin broke the news on her blog on Friday. I was out of town over the weekend, but made it down to the park to confirm the bad news.
Sadly, it looks like Laura made the right call. Searches of nearby branches and trees yielded no early fledgling. I heard an American Robin making alarm calls, but the robin had found one of the parents on a western branch of the nest tree about 15 feet from the nest.
