Here's a bit of a study on the Seagull, a.k.a. Laridae, from the order of Charadriiformes.
First, I have determined that they are curious things.
They're also a bit greedy and will stick around if there is potential for a snack.
They're stubborn. This guy just wouldn't move or go away so easily.
They're a bit awkward when walking (though any walking is impressive with those little legs, I have to say).
They have a good sense of style, since they always seem to choose the prettiest places.
