762 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



27, 7662, has the wing 3.84 ; the tail 2.90, and the bill 0.60 ; this is a pro- 

 nouncedly cinnamonimous individual ; the sex was not determined. 



The smallest of the Straits birds which have been examined are larger 

 than the birds taken at high altitudes and it may be that separation into 

 at least geographic races may be found expedient ; for the present and with 

 the material available the birds from the several regions are included under 

 this head as a tentative position to work from. 



While it seems possible that the birds referred to by the many students 

 who have seen them alive are true Cinclodes fusciis, the biography of the 

 species as here given is restricted to observation in the vicinity of the Straits 

 of Magellan ; and even here there may be opportunity for question as 

 to just what bird is meant unless the collector has carefully studied the 

 group. It is likely however that aside from the difference in habit caused 

 by local conditions these birds will be found to have similar life histories 

 even though they be specifically distinct. (Scott Ms.) 



W. H. Hudson says of it: "The Cinclodes fusciis is also a lively bird, 

 and quick in its motions on the ground, but when perched on trees sits 

 motionless in one posture. They are quarrelsome and sportive, and when 

 pursuing each other utter a trilling excited cry. Occasionally on a warm 

 day they attempt to sing, darting up from the ground as they utter their 

 notes; but their voice is as destitute of melody as their plumage is of 

 brilliant hues." 



Mr. Peters did not find it at Rio Colorado or San Antonio during August, 

 but they appeared with the first wave of migrants from the north on Sep- 

 tember 6 at Huanuluan and all had passed by early November. It was 

 fond of wet meadows or small brooks. (Bull. M. C. Z. Ixv. no. 9, p. 313.)
