The first step in the key is whether the toes are webbed or not. I can't tell from the picture whether or not they are webbed. If they aren't webbed, then that would tell you that the bird is a heron, which the picture is not.
So, if the toes are webbed, then you go to 2. This bird's beak is clearly longer than its head, so you go to 3. Since this bird has a black top of its head, this bird is an Avocet.
