|Black-legged Kittwake (1st cycle). Marseilles, Illinois; 22 December 2013.|
My only experience with a BLKI coming in this close was with a bird that was ill back in 2010 and ended up dying the day after we rescued it. This individual reminded me a lot of that bird. My suspicion was that the LaSalle County bird was either emaciated or just not too keen on surviving. Birders searched for it today (23 Dec 2013), without success.
