As for the weird department, here are two strange wild mallard captures.
First one - always thought mallards were strict herbivores until I shot this. AmberC was kind enough in the N&W forum to point out that they are, in fact, omnivores. Still, I've never before or since seen them being omnivoracious
Second one - a pair of mallards in a tree. In all the countless hours I spend in the field, I've only seen this twice. Btw, the male in this shot wasn't very good. He almost fell out a couple times in the wind.
