When I'm shooting senior portraits, I typically start out at Kathryn Albertson Park - a lovely natural park with lots of wetlands for nesting water fowl. And since the weather is getting nicer every day, the park was full of Canada geese guarding little flocks of goslings.

You have never seen anyone - human or animal - who can give a better stink eye than a Canada goose with little ones who thinks you are getting entirely too close for comfort. What do you mean, you don't know what stink eye is?
Take a gander (ha! goose joke!):

Give that goose a wiiiiide berth. Or else.
