Nice! always thought K was Kohl, now I know better

Lots of nice misdirection. I couldn't find the fourth bird (somehow I considered Teal and then didn't try it.) Saw CYMK but didn't know K stood for Key (I knew it was black). Only came together at the end when I got the card set (I had been thinking of bridge, so key or royal could have been part of the set, whereas gift and credit wouldn't be). Quickly got the blue set (again key could have been part of it, and maybe teal) and had not quite enough time for the last two. But recognized all the connections after that.
