I am so sad to report here that the Corn Crake was found dead this morning on Long Island. There is no immediate report as to what happened. I will update once I hear more. This is devastating news for the bird and for the hundreds of people still traveling to see it.
Addendum: a necropsy on the Crake revealed it had been most likely hit by a car. Both its legs and pelvis had been broken. It will have a permanent place in the Museum of Natural History. An extremely sad ending to a history making visit.
