Let’s start with a couple of ducks. This one winters across most of the Lower 48, but breeds in Canada and Alaska. It is heading north right now, so look for it on lakes and rivers. Hint: This image is of a female, but it shows the distinguishing feature that gives the species its name.
Identifying birds is at the very heart of bird watching. Each bird encountered is like a little puzzle or mystery to solve, because, while birds of a single species all share a certain set of physical traits, no two individual birds, like no two individual humans, are exactly alike.
