26 BRITAIN^S BIRDS AND THEIR NESTS. 



LEACH'S FORK=TAILED PETREL 



(Oceanodroma leucorrhoa). 



Leach's Fork-tailed Petrel nests in the St Kilda group, 

 in the Hebrides, and off the west coast of Ireland, and 

 is found in winter on various parts of our coasts, and 

 sometimes even inland after gales. In a general way it 

 may be said to resemble the Storm Petrel in appear- 

 ance and habits ; but it is rather a larger bird and has 

 a markedly forked tail. The eggs and nesting economy 

 are not very much different. The two other Petrels which 

 nest in the British Isles, the Manx Shearwater and the 

 Fulmar Petrel, are easily distinguished from these and 

 from each other.

THE MANX SHEARWATER 



(Puffinus anglorum). 



The Manx Sheanvater does not nest on the east 

 coast of the British mainland, but does so in Orkney 

 and Shetland, and on the west from the Hebrides to 

 Scilly Isles, as well as round the Irish coasts. The 

 most important colonies are on some of the Inner 

 Hebrides. As rats have exterminated the colony on the 

 Calf of Man, the name 'Manx' has no longer any 

 particular significance. Briefly described, this Shearwater 

 is a bird nearly as large as a Kittiwake, and has longish 

 wings and a skimming flight, dark -brown upper -parts 

 and white under-parts, and a rather long, hooked beak. 

 It shares with its close ally, the 'Lost Soul' of the 

 Bosphorus, the fictitious reputation of never alighting
