No. 89124.— Iris daik hrown. Bill clear yello-w, in front ol' nostrils tinged with apple-ftieen ; tip 

 whitish ; angle of mouth and the interior of the gape deep orange-red ; eye-ring vermilion. Feet 

 blackish brown, on the outside darker, brownish black : naked part of tibia on the inner side bright 

 orange-yellow, as are also one or two irregular spots on the inner corner of the wpb between middle and 

 inner toe. 



The Pacific Kittiwake, called by the natives " Gorarvschka,'^ on 

 account of its loquacity, is a common breeding;- bird, both on the islands 

 and along the Kamtschatkan coast, but as all places <lo not suit these 

 noisy birds or supply all their requirements the rookeries are compara- 

 tively few, a compensation for which is found in the astonishing num- 

 ber of individuals inhabiting each rookery. For such are chosen steep 

 walls, rising perpendicularly out of the deep sea, and especially high 

 pinnacles standing lonely amidst the foaming breakers, provided they 

 are lifted out with shelves and ]>rojections upon which to place the 

 nests. 



As Copper Island offers such localities all around its shore, the 

 Kittiwake is pretty well distributed all over that island. (>n Bering 

 Island, on the other hand, only the soutliern part has suitable rook- 

 eries, but here the red-legged Gavarnschka excludes it from Cape Man- 

 atee to l*eregrobnij. The first rookery of any importance on the west- 

 ern shore is among the cliffs of Dikij Mys. 



The only rookery I had the opportunity of visiting on the coast of 

 Kamtschatka is situate<l on a pinnacle-shaped rock, called the sentinel 

 (Tschasovoj), close to the island south t)f the entrance to Avatscha Bay, 

 called Staritskoft" Island. It is the same visited by ^ . Kittlitz, more 

 than half a century ago, and as I have nothing to add to his interesting- 

 account (Denkw., II, p. 214, seqv.), I shall only remark tliat I found the 

 Kittiwake as numerous at the present time as it was on the day when 

 he lost his gun on the "Tschasovoj."
