According
to Cornell’s All About Birds, the Red-tailed Hawk, (Buteo jamaicensis) is the most common hawk in North America. In our own experience at certain times of
year, for example, while traveling to Hagerman National Wildlife Refuge you will see one after
another, perching in trees or on light poles, along Refuge Road. You can judge
the size of their territory by the distance between them.
Red-tailed Hawk at HNWR, by Carl Hill |
These
large birds are easily identified when sitting, by the white front with the
belly band, and the red tail. In Hawks
in Flight, (2nd Edition) by Dunne, Sibley and Clayton) we read
that the basic ID for the Red-tailed is “big, broad, lumpy winged, and short-tailed.”
Weighing up to three pounds, the
Red-tailed hawk’s size allows it “to soar and glide, with little or no wobble”.
In the hawk family, Red-tailed
hawks show the most variation in plumage – example - Harlan’s Red-tailed Hawk, and the highest incidence of partial albinism - example
- Krider’s Red-tailed Hawk.
They feed
primarily on mammals, and we recently read somewhere that some hawks have
adapted to life along the “fast lane” and hang about highways waiting for
speeding vehicles to deliver freshly killed or wounded “dinner”.
The term "hawk-eyed" is based on the fact that in members of the Family Accipitridae, Hawks and Allies, visual acuity is 4 - 8 times
that of humans, and some raptors can spot small prey more than a mile away.
In relation to the head-size, some birds of prey have eyes larger, relatively,
than human eyes. (The Sibley Guide to
Bird Life and Behavior).
Red-tailed
hawks may be found in any open habitat. They
nest in tall trees or cliff edges, building or re-using a substantial nest of
sticks that is 3’ across up to 6.5’ deep.
A pair will have one brood, with 1 - 5 eggs.
According
to Cornell, the shrill cry of any raptor in a movie is probably the cry of the
Red-tailed Hawk. To hear various
Red-tail calls, you can go to http://www.allaboutbirds.org/guide/Red-tailed_Hawk/sounds.
Pale
Male is the most famous Red-tailed Hawk; this New York City resident has been
the subject of a PBS documentary and has his own website (http://en.wikipedia.org/wiki/Pale_Male).
