Everett is a
male American Kestrel (Falco Sparverius). Everett came to WSU in
2007 from a local sanctuary called Cattails in exchange for a large python.
He suffers from a slight shoulder injury, but is still able to fly a little,
but not enough to be released.
American Kestrels are the smallest falcons in North America and are the
second smallest falcons worldwide. In most species of raptors, the male and
female look alike in appearance. DNA testing may be required to be sure of
the sex of a particular raptor. With kestrels, color dimorphism between
males and females makes visual sex determination easy. Male American
kestrels have spots on their chests and bellies, a bluish-gray streak on the
top of their wings, and a solid, black terminal tail band. Females, on the
other hand, have brown stripes on their chests and bellies, completely brown
wings (no blue streak), and multiple brown bars on their tails, rather than
just one.
All falcons have a few unique characteristics in common: malar stripes, a
falcon's "tooth", nasal tubercles and long pointed wings. Malar stripes are
black stripes that run vertically down the sides of a falcon’s face and
provide protection from sun glare. The same principle is used by football
players by applying black paint below their eyes.
A falcon's "tooth" is a small projection that all falcons have at the distal
part of their upper beaks. A notch to accommodate the falcon's "tooth" is
present in the lower beak. This "tooth" is used to help kill prey quickly
and efficiently. The falcon's tooth fits neatly between the vertebrae of the
mouse and the bird clamps down to snap the neck of its prey.
Falcons also have very long, pointed wings that help them dive at
breath-taking speeds. Their wings fold back sharply at the wrist and when
diving, they keep their wings tucked to their bodies to decrease air
resistance. The peregrine falcon is the world’s fastest animal and is able
to reach speeds over 200 MPH in a dive! Talk about fast! American kestrels
probably only reach diving speeds up to 50 or 60 MPH.
American kestrels are not a threatened species. They are very common and can
be found throughout the continental U.S., in to Canada and parts of Mexico
and Central America. They are associated with open grassland areas and can
be seen hunting from telephone wires to take mice, voles, insects
(especially grasshoppers), small songbirds, and occasionally small snakes.
Kestrels are one of only a few birds that can actually hover in flight on a
windless day. Many other raptors such as hawks will hover the air on
thermals or other wind currents, but the kestrel can actually remain
stationary in flight without air movement. Other birds known to accomplish
this feat are hummingbirds and kingfishers.
