This month I would like to
introduce you to Willard, the Red-tailed Hawk, and some of the fascinating facts
about him and his species.
Willard's plumage is the Eastern color variation-note the distinctive red tail that gives this species its name.
If you haven’t already met
him at WBS’s Monsanto Environmental Education Center (also known as the
visitor’s center), I strongly suggest you make a trip out to see Willard. Willard is a Red-tailed Hawk (Buteo
jamaicensis).
Willard was orphaned when he was just a fluff ball of a
baby, and since we did not have any Red-tailed Hawk breeding pairs at the time,
we placed him with a pair of Harris’ Hawks so they could raise him. We wanted to make sure Willard did not
become imprinted on humans. These
hawks did a great job of raising him like he was one of their own.
Willard was hatched in the
wild in 1994, which makes him nineteen years
old this year. We know that
because he has been with WBS since he was just a chick. In the wild, Red-tailed Hawks live up
to 21 years and up to 29 years in captivity. The oldest reported Red-tailed
Hawk in captivity was 28 years and 10 months old.

Red-tailed Hawks are
native only to North America and are present year round in the continental
United States and Mexico. Their
summer breeding range is in some
northern states, Canada and even in southern Alsaka. Red-tails are the most commonly seen hawk in North
America. You won’t need to look
very hard to spot these birds outside.
They are often seen soaring over open fields or perched atop electrical
poles and trees along interstate highways and country roads.
These large hawks range
from 17 to 25 inches in length and weigh from 24 to 60 ounces (1.5 to 3.75 pounds). Their wingspan ranges from 3.5 to 4.5
feet. As with most birds of prey
it’s the females that are larger than the males. Males and females are not sexually dimorphic, meaning that
their plumage (feather color) is the same for males and females.
The Red-tailed Hawk has
one of the most variable plumages of any raptor, depending
on region. Besides the eastern color
variation like Willard, there are dark morphs and light morphs including, a
Krider’s subspecies, Harlan’s subspecies, Rufous morph, and there are many
reports of Albino and lucistic Red-tailed Hawks. Krider’s hawks are more often found
around the Great Plains in the United States and Harlan’s hawks are found in
Canada and Alaska. Below you can
notice the difference in plumage.
Note the much lighter plumage on this Krider's sub-species
Red-tailed Hawks are a
type of bird of prey, which puts them into the category of being a
carnivore. These hawks will eat
mostly mammals, but will go after snakes, small birds, and carrion (dead
animals). A common name most
people give these hawks is the “chicken hawk” because they are known to
sometimes prey on chickens, but Red-tailed Hawks
mostly go after small mammals. If you have ever gone to a cinematic
adventure (the movies!) and heard a bird of prey calling, it was most likely a Red-tailed Hawk
call. (To hear some of
the calls made by a Red-tailed
Hawk click on the link and then scroll down on the page.) Their call is the most common bird of
prey call to be used even if the bird in the movie is not a Red-tailed Hawk!
Willard
is available for adoption in our Adopt a Bird program. To find out more information, call
636-861-3225. All adoption
donations are tax deductible.
Unless
he is traveling to an education program with our Naturalists, Willard can be
seen year round in the weathering area behind the Monsanto Environmental
Education Center at the World Bird Sanctuary. The World Bird Sanctuary is open daily from 8am-5pm.
Willard
is a very handsome bird. You
should stop on by and visit him!
