and were followed by the Cape Petrel (Daption capensis) and 

 the Adelie and Gentoo Penguins (Pygoscelis adelice and 

 P. papua) . 



The first spring immigratory movements took place in 

 October, when Cape Petrels, Adelie and Gentoo Penguins, 

 Skuas, and Terns {Sterna hirundinacea) arrived in the order 

 indicated, the last-named at the very end of the month. 

 These were followed in November by Wilson's Petrel 

 (Oceanites oceanicus), the Ringed Penguin, and the Silver 

 Petrel (Priocella glacialoides). 



With the return of spring the explorers were busy and 

 journeys were undertaken in various directions, while a camp 

 was established on the northern shore of the island, which 

 was productive of excellent ornithological results, but had 

 unfortunately to be abandoned at an interesting period on 

 account of the break up of the ice. 



After haviug been icebound for eight long months, the 

 'Scotia' was liberated on November 23rd, 1903, and imme- 

 diately departed for the Falklands and Buenos Ayres to 

 refit ; but a party under the charge of Mr. Mossman, the 

 meteorologist, and Dr. Harvey Pirie, the medical officer and 

 geologist, was left to carry on the various observations and 

 investigations and to make collections throughout the 

 summer months. It is to the assiduous labours of Dr. Pirie 

 that we owe most of our knowledge of the bird-life of the 

 island during this most interesting part of the year, and 

 he has earned the best thanks of ornithologists for the vast 

 amount of valuable work which he accomplished. 



During the summer bird-life was extremely abundant. 

 Rookeries of the three species of Penguin (Pygoscelis) were 

 numerous on the low rocky shores and less steep cliffs on 

 various parts of the coast. Some of these bird-cities 

 contained several millions of inhabitants, and their daily 

 life presented scenes so remarkable as to be almost beyond 

 description. The cliffs and their screes were the home of 

 several species of Petrel, which resorted in great numbers to 

 the ledges and crannies for nesting-sites, and the shores 

 were the abode of the Gull, the Skua, and the Tern.
