BIRDS. 



Procellaria leucorrhoa, Fieill Fork-tailed Petrel. 



Rarer than the last, as to be expected according to its known dis- 

 tribution, which is more upon the west coast during its breeding 

 season. 



There is one recorded as having been obtained near Strathallan 

 Castle, Strathearn, on 22nd November 1881 — an adult female. 



Another was got at Blair Castle, Atholl (see Scot. Nat., 1881, 

 p. 207). 



Puffinus anglorum (Temm.). Manx Shearwater, 



Occasional off the coast. (Perhaps regular.) 



Col. Drummond Hay was no doubt correct in his identification of 

 one he believed to be of this species which he saw off the mouth of 

 Tay ; but the possibility of course exists that it may have been one 

 of some other, and perhaps rarer, species. 



One was taken at Waukmill, some nine or ten miles inland. It 

 was on the mill-pond when first seen, and was caught in the hen- 

 house, where it had taken shelter, and was given to Mr. J. Milne 

 (J. Milne, in lit., 15th September 1899). 



Mr. A. Nicol Simpson mentions another obtained at Johnshaven 

 in the fall of 1899 (Annals Scot. Nat. Hist., 1900, p. 201). 



Mr. W. Evans reports having seen a small flock of Manx Shear- 

 waters off St. Andrews harbour on the 25th September 1886, and 

 asks the pertinent question, " What were they doing there 1 " (in lit.), a 

 question as regards the genus, as well as this species, usually hard to 

 answer (see under our information about the Great Shearwater and 

 the Sooty Shearwater in our previous volumes) ; and Mr. Evans again 

 writes me that he finds the tisual flight of Manx Shearwaters in Forth at 

 about midsummer 1905. 



All the Petrels and Shearwaters are great vagrants, as is well 

 known (witness the numbers of the Great Shearwater which visit our 

 western seas), but until we can know more about their changes of 

 plumage, and the ages at which they begin to breed, I fancy we 

 must be content to await further developments before we can decide 

 several points about their history. 



Puffinus major, Faber. Great Shearwater. 



So far as I know, only the sternum of one of these birds gives any 

 evidence of its occurrence on this coast. This solitary fragment was
