On the morning of Saturday, February 10,
2001, Paul Sykes reported that he had discovered an adult male
Rough-legged Hawk northeast of Athens near the community of Comer, Madison
Co., GA.
Earl Horn and I decided to head over to
this area the following morning to see if we could relocate the
bird. As we pulled up to the site, Earl quickly spotted the bird on
the top of a telephone pole. Although the bird had its back to us,
it was readily identifiable as a Rough-legged Hawk due to the bold tail
pattern and pale head coloration.
As we drove by the hawk to get a different
view, it abandoned its perch and headed to the edge of some woods
bordering the field it was previously surveying. Earl re-found it perched
in a tree, where we were able to study it at length through scopes.
As we were watching it, I decided to sketch the bird and take a few notes
(see the last photo, at left) in case we were unable to take any photos.
This particular bird proved quite difficult
to photograph, and we were unable to get within a reasonable distance,
hence the very poor quality of the other photos.
We watched the bird for over two hours,
most of the time as it hunted and soared over the surrounding pastures and
fields. As it hunted, it utilized both hovering and kiting
techniques extensively to study the ground for a potential meal.
We noted the following characteristics
about this bird:
While perched:
-
Size, similar to Red-tailed Hawk; there
were a couple of Red-tails, several Turkey Vultures and three Northern
Harriers (males and a female) in the area affording convenient size comparison.
-
Overall shape was similar to that of a
Red-tailed Hawk, with the exception of the head and beak size, and
primary length (when compared to tail length).
-
Head appeared proportionately small for
the body.
-
Beak appeared proportionately smaller
still for the head.
-
Head coloration was a pale buffy white
color with fine black streaks and other markings. Distinctive
were the black lores, eyeline and cheeks, which widened and continued
along the side of the throat to the side of the breast. The
markings on the face gave the bird a falcon-like resemblance.
-
Overall body coloration was generally
quite pale, but certain areas were heavily marked with blackish bars, especially on the sides, flanks,
and back. In my notes, I wrote that the back was "blackish
with heavy white mottling", but it probably would have been more
accurate to describe it as whitish with heavy black, or dark,
markings.
-
The central portion of the belly did
not have the heavy markings of the flanks, with which it contrasted.
-
The completely feathered legs were
never really visible while the bird was perched; they were obscured by
the flank feathers.
-
The wings were generally quite dark
(especially the primaries), but the secondaries were noticeably edged
with a very light color.
-
Primary tips at least as long as tail.
-
The undertail coverts appeared to be
white and generally unmarked.
-
The tail possessed a distinctive
pattern: The base of the tail was mostly white, gradually
darkening to a dusky band, then a thin blackish band, a dusky band, a
slightly wider blackish band, another dusky band, a wide black band,
and finally a pale and somewhat thin terminal band.
In flight:
-
Appeared somewhat long-winged and
long-tailed.
-
Wing shape differed from a Red-tailed
Hawk in that the secondaries did not "bulge" towards the
middle.
-
Underwings were heavily patterned, but
most distinctive were the black carpal markings.
-
The flight feathers were predominately
whitish with dark tips.
-
Underwing coverts heavily patterned
with whitish and black markings.
-
Leading edge of wings were pale.
-
Upper tail coverts mostly dark with
scattered white markings, contrasting strongly with the white base of
the tail.
