longer feathers are passed between the mandibles, and the short 

 feathers of the body and lower neck are vigorously manipulated 

 with the tip of the bill. This individual is almost constantly 

 engaged in some activity, and the number of peculiar positions 

 into which it can twist its neck is surprising. We secured 

 photographs of some of these, but they do not include the most 

 awkward positions nor show the remarkable loop formed by 

 the neck when the bird preens the feathers of its throat. 



The following color notes were made from this living bird 

 and from a specimen killed when this one was captured: Iris 

 honey yellow, the outer border and a narrow inner ring prim- 

 uline yellow; skin below eye dark olive-ocher, above eye and 

 at base of bill light yellowish olive; bill yellowish olive, but 

 proximal half of lower mandible light orange-yellow; tarsi deep 

 to dark olive-gray in front, iron-gray or darker behind; toes 

 dark olive-gray, webs yellowish olive.

Although the monkey-eating eagle has been definitely re- 

 corded from Luzon, its size and rarity warrant the recording 

 of additional notes of its occurrence. Through the interest and 

 the efforts of Gov. E. A. Eckman and Gov. Leo J. Grove a living 

 bird of this species was sent to the Bureau of Science in Jan- 

 uary, 1917. The specimen was captured at an altitude of about 

 1,200 meters on Mount Ballong, which is 6 kilometers west and 

 a little south of Imugan, Nueva Vizcaya Province, Luzon. This 

 is the most northern record of this eagle. Although I saw a 

 large eagle, probably of this species, at Irisan, Benguet Prov- 

 ince, the record must be always considered doubtful. 



Governor Grove kindly furnished the following notes about 

 the specimen secured by him : 



The eagle was c&ught with a bait and a snare. The bait was a small 

 pig and after it was placed several rattan nooses was placed around it 

 so that when the eagle made his swoop for the pig he would have to enter 

 one of them which drew tighter the more it struggled. The nooses were 

 made quite large but not large enough for the wings to pass through. The 

 noose being struck by the wings with the velocity of the body of the eagle 

 was caused to tighten and hold the bird securely. The same men have 

 promised to get me the mate of this one, but as they were six months 

 getting the one we have I have not very many hopes of their success.
