.'342 Mr. A. B. Brooke on the 



Oristano. I was greatly surprised to find, as late as the 7th 

 of June, 1871, a flock of from five to six hundred of these 

 birds, still remaining about the stagno of Quarto, near Cag- 

 liari ; and during the several days I watched them, they showed 

 no signs of restlessness, nor any desire to change their quarters, 

 but seemed in every way to have settled for the summer. I 

 was informed by Signor Cara (whom I always found most cour- 

 teous and obliging in giving me any information he possessed) 

 that it was extremely unusual for such a large number to re- 

 main during the summer, but that a few invariably did so. 

 They certainly do not breed there now, as a sharp look-out is 

 kept for their nests, and they could not escape observation. 

 Amongst the flock I noticed nearly as many adult birds as 

 young ; otherwise I should have imagined it was only the 

 young birds of the previous year that remained during sum- 

 mer. Early in the day the flock was scattered all about the 

 stagno in small parties of forty or fifty, feeding round the 

 shores ; but towards three or four o'clock in the afternoon 

 they all collected in one long line, extending quite a quarter 

 of a mile, near the centre of the stagno, where they slept with 

 their heads under their wings. They were extremely wild 

 and shy, rising a long way oft', with loud harsh cries. 



207. Phuenicopterus erithacus. 



I noticed a great difference in size in many individuals of 

 the flock above mentioned ; perhaps some might have been of 

 this species, which is included in Salvador's list. 



-*-208. Cygnus musicus. 



There are no specimens in the museum at Cagliari; but 

 they are, I believe, not uncommon during winter. 



209. Cygnus olor. 



Varies in numbers according to the severity of the winter. 

 Is the commonest wild Swan that visits the island. 



210. Anser ferus. 



A common winter visitor. 



: 211. Anser segetum. 



Common in winter. During the autumn migration large
