OF HAWKS
In strict usage in Europe and Asia,
to mean any of the species in the subfamily
Accipitrinae, which comprises the
genera Accipiter,
Micronisus,
Melierax,
Urotriorchis
and Megatriorchis.
The large and widespread
Accipiter genus includes
goshawks, sparrowhawks , the Sharp-shinned Hawk and others.
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" (Accipiters) as well as eagles, kites, harriers and
buzzards. Loosely, to mean almost any bird of prey outside
of the order Strigiformes (owls).
The common names of birds in
various parts of the world often use
hawk in
the second sense. For example, the Osprey or "fish hawk";
or, in North America, the various
Buteo
species (e.g., the Red-tailed Hawk,
B. jamaicensis).
In February 2005, the Canadian
ornithologist
Louis Lefebvre announced a method of
measuring avian "IQ" in terms of their innovation in feeding
habits. Hawks were named among the most intelligent birds
based on his scale.
Hawks are widely reputed to have
visual acuity several times that of a normal human being.
This is due to the many photoreceptors in the retina (up to
1,000,000 per square mm for
Buteo, against 200,000 for
humans), an exceptional number of nerves connecting these
receptors to the brain, and an indented fovea, which
magnifies the central portion of the visual field.
At Falconry-UK we have
three Harris Hawks.
All are Parent Reared and
we have had since birth.
