BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 115
Territory of Formosa, where the bird was more common. As at
Puerto Pinasco, this hawk was sluggish in its movements. At this
season it was found alone, usually perched in the top of some low
tree that gave command of an open space. Occasionally one sailed
along across the savannas a few feet from the ground on the
lookout for food. Grass fires attracted these birds, and I saw them
frequently near areas where fires were about burned out where no
doubt small rodents and other similar prey offered desirable food.
When on the wing the handsome markings of this beautiful bird
are displayed to the fullest advantage so that, save for the dark
tipped wings, it appeared wholly rich reddish brown.
The Toba Indians called this species mi yuh.
ACCIPITER GUTTIFER Hellmayr
Accipiter guttifer Hellmayk, Verh. OrnitK. Ges. Bayem, vol. 13, September
20, 1917, p. 200. (Bolivia.)
According to Bertoni ^^ Sparvius guttatus of Vieillot ^^ founded
on the Esparvero pardo y goteado of Azara ^ refers to the immature
of Accipiter pileatus (Temminck) ; in accordance with this, Hellmayr
has given the present bird, long known as guttatus^ the name
Accipiter guttifer.
A female shot at Tapia, Tucuman, on April 10, 1921, dashed into
a clump of bushes in front of J. L. Peters and me, in pursuit of
a small bird. On seeing us, hardly 3 meters away, it checked its
flight abruptly, alighted for an instant on a stump, irresolute as to
the best manner of escape and then darted off. When dropped with
a broken wing it ran swiftly on the ground.
The bird is an adult female in post nuptial molt, with new plumes
appearing in wings, tail, upper breast, crown, and back.
ACCIPITER ERYTHRONEMIUS (Kaup)
Nisus vel. Ace. erytlironemins " G. Gray," Kaup, in Jardine, Contr. Ornitli,,
1850, pt. 3, p. 64. (Bolivia.)
On February 19, 1921, at Rio Negro, Uruguay, one of these small
hawks was killed as it flew past bearing something in its talons.
Its prey, whatever it may have been, dropped in high grass where
it could not be found. Later another was seen on a perch near the
ground at the border of a small opening in heavy brush. As it
fiew it came near me and was secured. The long tail, rounded wings,
and the head apparently drawn in on the shoulders give this bird the
appearance usual in small Accipiters.
