Just before the rains came last evening, while walking the dog in my backyard, 
I heard a single 'qwok' looked up and saw a largish winged bird flapping 
rapidly NW which would be more or less on a path from Sapsucker Woods to Cayuga 
Lake (or many other ponds along the way).

Listening to all readily available recordings of Black-crowned and 
Yellow-crowned Night Herons convinced me it sounded more like BCNH. But the 
wing profile was rather narrow (leading to trailing edge) and the bird seemed 
overall rather darker blue. Googling flying Night Herons, I found more YCNH 
images that looked like that, whereas BCNH seemed to have a fuller rounder wing 

So, nice NEW yard bird, but semi-unsatisfying that I couldn't nail it to 

I saw no reports on this list from anyone observing either at SSW yesterday. 
Did anyone?
