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, Sep- 

 tember 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, Hell- 

 mayr 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)

 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.
