Great Egrets were hunted to near extinction in the 1930s for feathers
for use in women's hats. They are slowly recovering in some areas, but
their preferred habitats are also vanishing in many places. It has a
yellow bill and is a pretty good sized bird. They stand about three
feet tall, with total length from tip to toe about 40 inches. They have
a yellow bill, but black legs and feet.
What we call Cattle Egrets are thought to actually be from Africa. It
is thought they made their first appearance in South America sometime in
the 1940s, and have slowly expanded northward since then. They are
about half the size of a Great Egret. It has yellow legs and feet,
though mud may obscure this. Also, in the spring they have golden
plumage in various places on the neck. They are fairly common in places
where there is livestock kicking up insects, but its range expansion
hasn't hit the western states as much as the eastern states - at least
not yet.
Either way, the bird is increasing in number.
There is a third type of egret that is fairly likely in winter in
Arizona.
In Arizona I would expect they might be Snowy Egrets. These are about
the size of a Cattle Egret (only slightly larger), but have a black bill
instead of a yellow bill, and black legs.
