3292 THE ZooLoGisTt—NoOvEMBER, 1872. 
131. Slercorarius pomarhinus, Temm. Pomatorhine Skua. 
Miiller writes that only two young individuals of this species have 
fallen under his observation in the Feroe Islands (‘ Feroernes 
Fuglefauna, p. 64). 
132. Stercorarius parasiticus, Linn. Richardson’s Skua. Native 
name, Tjegvi.—This bird arrives about the beginning of April and 
leaves in October. In the middle of May I noticed them pairing: 
at this period their flight is still more striking than usual; generally 
the female is pursued by two, sometimes by three, males. For hours 
together they remain on wing, indulging in the most varied flights, 
now sweeping the ocean or fiords, anon rising over the very summit . 
of the hills, then away down the valleys and around the lakes. So 
rapid is their flight that the “whish” of their wings is startling as 
they pass you unexpectedly from behind. This elegant bird is 
most abundant throughout all the islands, but especially so in 
Vaagoe and Svinoe; though apparently preferring certain spots 
where many pairs nested in proximity, yet we found their nests 
scattered over the islands. I have frequently watched them pur- 
suing the arctic terns, but sometimes they did not succeed in 
making this bird disgorge, for often the mate of the chased tern 
would come to the rescue, attracting the attention of the predatory 
gull, so that at length, between the two, the skua became quite 
baffled, and gave up the pursuit in disgust. This bird is a regular 
attendant on the fishing-boats when they return from the sea, and 
comes in for a large share of the fish-offal, which it robs the gulls . 
of, but I remarked as well that it does not disdain to help itself 
more honestly from the garbage when thrown out on the water. 
I am inclined to think that the variations in colour of the plumage 
are entirely dependent on age, and that the birds with most white 
in the plumage are the oldest. 
133. Stercorarius ceppus, Brunn. Longtailed Skua. Native 
name, Tjegvii—Is uncommon. Miiller procured one individual in 
June, 1860, and another in 1863. I did not recognize it, though 
I looked carefully amongst the preceding species for it. 
134. Fulmarus glacialis, Linn. Fulmar Petrel. Native name, 
Heavhestur.—Svabo writes that in his day it was only seen by the 
fishermen far off the coast. Landt mentions that it is seen between 
the Shetlands and the Feroe Islands, and is known only to those 
who fish a great way out at sea. I noticed it following the steamer 
after we got about thirty miles north of the Shetlands, and their
