In my previous post, forgot to mention both KINGLETS.  I normally wouldn't consider that omission worthy of a second post, but for the numbers.  Plenty of GOLDEN-CROWNED, but it was RUBY-CROWNED that really seemed to be everywhere--my conservative estimate was 15, but there may have been many more.  

Also perhaps worth mention was a flyby Sapsucker.
