Among many hundreds of these ducks seen in the Falklands, all, 

 except perhaps in size (Mr. lilaauw gives no measurements) answer 

 absolutely his description of what he diagnoses as T. patachonicns. 

 No birds of dark phnnage, the females, even had yellow bills, and no 

 females were seen in anything that could possibly be referred to as a 

 gray plumage. And out of many hundreds seen none took flight, 

 although I do not doubt for an instant that a small percentage can fly. 



This duck like so many other birds in these islands is very tame, 

 especially in the harbor of Port Stanley. 



They are quite curious, often swimming near if one sits cjuietly on 

 the beach. If anything disturbs a flock others will swim up to see 

 what caused the commotion. 



The call of the female is a hoarse, rasping sound that can be heard 

 a consiflerable distance. The male's thin, wheezy " Kee-u-kee-u- 

 kee-u" sounds more like a sneeze than anything else. 



Like the penguins they can go through the most heavy surf, but 

 often harder work is made of it. 



Nesting begins early in October, the nest being placed in grass, 

 ferns, or " Diddle-dee" bushes, as far as half a mile from the sea. 



The first downy young were noted on November 1(), and from this 

 date until December 26, new broods were seen, the largest containing 

 seven. At this time the parents are very Avary and at the distant 

 approach of man swim a long distance from shore with the brood. 

 The young immediately upon hatching are able to dive and swim 

 well under water. 



Adults are fond of feeding in shoal water along the stony beaches, 

 where they dip like "river ducks." They make an unusual amount 

 of noise when diving, and on a still evening the splashes suggest the 

 rising of trout in some northern "still-water." 



Their food includes all manner of small marine animal life. A 

 single stomach dissected contained limpets, small chitons, mussels, 

 \arious gasteropods and bivalves, shrimps, and two species of crabs, 

 the carapace of the larger being two inches long by one inch wide 

 which with its legs must have been a large object to swallow. 



The weight of IvOggerhead Ducks has been greatly exaggerated by 

 old writers. Captain Cook claimed that they weighed twenty-nine 

 or thirty pounds. Coppinger in the cruise of the Alkht, LSSli, foimd 

 fourteen pounds to be the heaviest. Thi$ is rea.sonal)le although my
