AVES ANATID./B. 449 



strong rufesccnt shading ; the feathers on the breast with a darker brown 

 rufesccnt spot in the center of each ; these markings are not well defined 

 on the sides and flanks, where the feathers are heavily splotched and shaded 

 with dull rufescent brown ; these brownish marks take the form of obscure 

 barring on the abdomen ; the lower tail-coverts reach quite to the tips of 

 the tail feathers proper, are pointed in shape at their ends and of deep 

 velvety black color. 



Bill : Black. 



Iris: Yellowish red (Hatcher). 



Feet: Dark lead-color (Hatcher). 



The female is similar to the male in color, but is a little smaller and the 

 crest is not so well developed. 



Geographical Range. Southern Peru, Chili, Argentina, the Magellan 

 Straits and Falkland Islands. 



The Crested Duck was met with by the naturalists of the Princeton 

 Expeditions at Montes Ranche, near Mount Tigre, Patagonia in August 

 1896. From here they sent home a pair of these birds in full plumage, 

 which have in part formed a basis of the foregoing descriptions and figures. 

 The point where these birds were collected, southern Patagonia near the 

 Atlantic Coast, and the season of the year, would seem to indicate that 

 this species is not a migratory bird ; for Cunningham found crested ducks 

 common at Peckett Harbor in February and the birds must have been 

 through with breeding at that time. 



This seems to be a common bird and very generally distributed through- 

 out the Patagonian region ; beside the points already indicated through 

 the work of Mr. Hatcher and Dr. Cunningham, every naturalist who has 

 visited the region has encountered the birds at some locality ; specimens 

 from the Museo de La Plata, now forming part of the Princeton collec- 

 tion, were taken in the Province of Chubut in February, 1897. 1* th us 

 appears that the bird is present at the limits of its north and south range 

 at the same season of the year. 



The eggs of this duck have been taken in January in the Bolivian Andes, 

 in December in the Falkland Islands, and at Elizabeth Island on the west 

 coast of Patagonia in January. 



"Next morning (i2th) [February, 1887] we left Sandy Point, and 

 proceeded northward along the Patagonian coast, on the look-out for the
