Order: Falconiformes (Accipitriformes)
|Buteo (Etymology: Buteo is the Latin name of
the Common Buzzard) is a genus of medium to fairly large, wide-ranging
with a robust body and broad wings. In the Old World, members
of this genus are called "buzzards", but "hawk"
is used in
North America. As both terms are ambiguous, buteo is sometimes
used instead, for example, by the Peregrine Fund.
The term hawk can be used in several ways:
In strict usage in Australia and Africa, to mean any of the
species in the subfamily Accipitrinae,
The large and widespread Accipiter
genus includes goshawks, sparrowhawks, the Sharp-shinned Hawk
These are mainly woodland birds with long tails and high visual
acuity, hunting by sudden dashes from a concealed perch.
More generally (especially in North America) to mean falcons
or small to medium-sized members of the Accipitridae
the family which includes the "true hawks" as well
as eagles, kites, harriers and buzzards.
Buteos range in size from the Roadside Hawk, which averages
270 grams and 35 cm long, to the Ferruginous Hawk and Upland
Buzzard, both at 1,350 grams and 60 cm long. They are noted
for their broad wings and sturdy builds. The Buteos frequently
soar on thermals at mid-day over openings and are most frequently
seen while doing this. They inhabit a wide range of habitats
across the world but tend to prefer some access to both clearings
All Buteo species are to some extent opportunistic when it comes
to hunting, and will prey on almost any type of small animal
as it becomes available to them. However, most have a strong
preference for small mammals and among these mostly rodents.
Rodents of almost every family in the world are somewhere predated
by Buteo species. Birds are taken occasionally, as well, although
most small birds can successfully evade them. Mid-sized birds,
such as waterfowl, corvids, pigeons and gamebirds, are most
often taken, but even these are generally taken when distracted.
Other prey may include snakes, lizards, frogs, salamanders,
fish, and even various invertebrates, especially beetles. Carrion
is eaten occasionally by most species, but is almost always
secondary to live prey. Prey is often spotted from a great distance
while soaring and is set down upon while circling down to the
ground. Other Buteo species may prefer to ambush prey by pouncing
down to the ground directly from a perch.
The Buteo hawks include many of the most widely distributed
and best-known raptors in the world. Examples include the Red-tailed
Hawk of North America, the Common Buzzard of Eurasia, and the
Roadside Hawk of tropical Central and South America. Most Northern
Hemisphere species are at least partially migratory.
In North America, species such as Broad-winged Hawks and Swainson's
Hawks are known for their huge numbers (often called "kettles")
while passing over major migratory
flyways in the fall.
