500 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



young travel through the water nearly as fast as the adults, in which the 

 muscles of the legs are enormously developed. The call-note of this 

 species, which I only heard uttered when there were young near, was a 

 croaking quack. The pilot who took us through the Straits of Magellan 

 told me that there are not so many of these Ducks there as formerly. I 

 saw only two in the Straits of Magellan, and did not obtain a specimen 

 until we got into Smythe's Channel. The gizzards of those shot con- 

 tained broken mussel-shells [Mytilits inagell aniens).'' (M. J. Nicoll, Orn. 

 Jour. Voy. Round World, Ibis, 1904, pp. 49-50. February, 1903.) 



651, female (young), Messier's Channel. 



"Eyes brown ; stomach had crabs." 



656, young, Messier's Channel. 

 "Eyes brown, feet and bill black." 



657, female, Tom Harbour. 



"Eyes brown, bill yellow tipped with black, feet yellow; stomach had 

 small pieces of sand." 



678, male. Straits of Magellan. 



681, 682, females, Fort Churrucha. 



"Weighed 8 lbs. and 8^ lbs." 



725, 726, males (young), Falkland Islands. 



"Stomach had shells from the kelp chiefly; bill black, feet yellow- 

 brown." 



There is nothing in the present series which would induce us to ques- 

 tion Dr. Cunningham's view, that the "Flying Loggerhead" is the young 

 of the ordinary species before it gets too heavy for flight. Such a speci- 

 men as "No. 651, young female," could evidently accomplish flight, 

 which in large fully adult birds would be probably impossible. 



In all the immature birds the bill is uniform black. (Sclater & Salvin, 

 on Birds Antarctic America, Voy. H. M. S. "Chalk," No. ix. p. 437, 1878.) 



"Female: Puerto Buenos. Legs and feet yellow; bill greenish olive; 

 eyes black. Shot on freshwater lake near the sea. 



"Walney Sound, February 4, 1879. Weight io>^ lb. Crop full of 

 entire mussels and prawns. Stink intense." (Sharpe, P. Z. S. 1881, p. 

 13-)
