I like the "evil" look many ducks can have when looked at straight on. This one was actually looking for a handout. With many mallards, and quie a few Wood Ducks as well, it was a challenge isolating just one individual as they all eagerly came in for seeds. The trick was to throw some food very far - have them all go to that - and then throwing some closer and photographing the leading bird(s) swimming back in as all the others were still busy with the far stuff. Fun times!
