American Black Duck |
In order to identify a bird accurately many things need to be taken into consideration, such as body, bill, wing and tail shape,or eye stripes, crests, spots and streaks, color etc. Some birds however are especially difficult to distinguish from other species of birds, either because they appear to be almost identical to another species, or they have very few identifying field marks.
This is where the color of a bird's feet, bill or legs can come in handy. Some birds have very bright and colorful legs, like the American Black duck and the Lesser Yellow legs, and some have lightly colored legs, such as pink, gray and even green. The same holds true for bills and feet.

Notice that I simply labelled the photo above as Egret. This is because the image is unclear and I do not have sight of the whole bird. Although it seems to have a bi-colored bill the, bird is partly in shadow, and I can't see the legs accurately at all, so it makes it difficult to tell. Unfortunately it is the only photo I have and my camera equipment at the time did not produce the greatest images. Hopefully I will see this bird again in the future.
Enjoy,
Susan
