              SHARP-SHINNED HAWK.
              [Plate XLV.-Fig. 1, Female.]
  IHSH is a bold and daring species, hitherto unknown to na-
turalists. The only Hawk we have which approaches near it
in colour is the Pigeon Hawk, figured in plate 15. But there
are such striking differences in the present, not only in colour,
but in other respects, as to point out decisively its claims to
rank as a distinct species. Its long and slender legs and toes;
its red fiery eye, feathered to the eye-lids; its triangular grooved
nostril, and length of tail, are all different from the Pigeon
Hawk, whose legs are short, its eyes dark hazel, surrounded
with a broad bare yellow skin, and its nostrils small and circu-
lar, centred with a slender point, that rises in it like the pistil
of a flower. There is no Hawk mentioned by Pennant, either
as inhabiting Europe or America, agreeing with this. I may
therefore, with confidence, pronounce it a nondescript; and have
chosen a very singular peculiarity which it possesses, for its
specific appellation.
  This Hawk was shot on the banks of the Schuylkill, near
Mr. Bartram's. Its singularity of flight surprised me long be-
fore I succeeded in procuring it. It seemed to throw itself from
one quarter of the heavens to the other, with prodigious velo-
city, inclining to the earth; swept suddenly down into a thicket,
and instantly re-appeared with a small bird in its talons. This
feat I saw it twice perform, so that it was not merely an acci-
dental manceuvre. The rapidity and seeming violence of these
zig-zag excursions were really remarkable, and appeared to me
to be for the purpose of seizing his prey by sudden surprise, and
main force of flight. I kept this Hawk alive for several days,
and was hopeful I might by able to cure him; but he died of his
wound.
