Golden Eagle (Aquila chrysaetos)
May 25, 1937 north 20 miles E., Warner Valley, Oregon - A pair
of these birds first seen flying high above
canyon. They suddenly almost completely
folded their wings and plummeted obliquely
down toward the north ridge
of the canyon. A little later (6:00 P.M.) one and
possibly two, eagles flew low along the side
of the canyon's north ridge. A pair of Red-
tailed Hawks appeared above the eagle and
several times, as individuals, dove on the
eagle in bold, long vertical plunges. This was
done with such agility that the hawks were
at first mistaken for Prairie Falcons, which
I already know, may drive Golden Eagles from
either their territory or their own.
