314 BRITISH BIRDS. [vol. vn. 



common on shingle banks and low rocks, and on the adjoining 

 greenswards. A favourite haunt also is the outer harbour 

 and neighbouring pier at Castletown, and the adjoining 

 stony and weedy foreshore. The season of this autumn- 

 migration extends from July to October, but the birds are 

 most numerous in September. 



Our Pied Wagtails, on the contrary, seem to inhabit the 

 neighbourhood of the same brook or farmyard for the 

 whole year. 



Dipper {Cinclus cindus ? subsp.). — Another unfinished 

 nest (of 1912) w^as shown me last summer by Mr. W. E. 

 Cottier, in the Cluggid Gorge, Sulby Glen. Mr. F. A. Craine 

 says that Dippers nested in 1913 under the bridge over 

 the Glass at " Le^vthwaite's Mill " at the entrance to East 

 Baldwin. 



Common Heron {Ardea cinerea). — ^Mr. F. S. Graves ascer- 

 tained beyond doubt that in 1912 a pair nested in a tree at 

 Injebreck. At least two young were seen in the nest. 

 In 1913 the birds again frequented the locality, but their 

 breeding-place (if they did breed) was not discovered. 



Mrs. Jeffcott, of Castletown, who recently died at a great 

 age, was long ago told by an old man that Herons once 

 bred in trees at the Crofts, in the town of Castletown ; at 

 that time no street had yet been formed in that locality. 



Manx Shearwater {Pufflniis p. puffinus). — Mr. Graves 

 continues to observe this species, evidently on its feeding- 

 ground, when crossing between Douglas and the Bar light- 

 ship. On August 13th, 1913, when near the Bar, he saw 

 in addition to a number of this species, another Shearwater, 

 much larger and of dark plumage both above and below, 

 flying in the same way as the others, but though near them, 

 not actually associating with them. 



Purple Sandpiper {EroUa m. maritima). — A small flock 

 still, each winter, frequents the same locality at Scarlett. 



Redshank [Tringa totanus). — Seems yearly to be increasing 

 in numbers, and I constantly notice it in new localities 

 (never in the breeding -season). 



Black Tern {Hydrochelidon n. nigra). — ^Early in May, 

 1913, Mr. H. J. Kinley saw on the Smelt Dam, Port St. Mary, 

 a bird which from his very exact description can have been 

 of no other species. 



Common G-ull {Larus c. canus). — In the late summer of 

 1913 a few appeared in Castletown Harbour among numbers
