THE BIBDS OF SCILLY. 247 



in evidence on almost every island, including even Mincarlo and 

 Castle Bryher. The Nuthatch has not been seen, and there is 

 no certain record of the occurrence of the Tree-Creeper. The 

 Pied Wagtail is common all the year round, and nests on all the 

 larger islands. In the autumn large flocks arrive from the main- 

 land. The White Wagtail is a not uncommon casual autumn 

 visitor, coming over with the migrant flocks of Pied Wagtails. 

 In a large flock of the latter, which arrived on St. Mary's early 

 in October, 1903, seven of the former were counted. David Smith 

 saw several on Tresco about the same time. The Grey Wagtail 

 is a regular autumn migratory visitor, sometimes in large flocks, 

 as in October, 1903. It has not hitherto been recorded as a bird 

 of passage in the spring, but in 1903 it was common about Hugh 

 Town, St. Mary's, from April 10th to 18th. Two specimens of 

 the Blue-headed Wagtail were obtained by Pechell in September, 

 1871, but it has not been recorded since. The Yellow Wag- 

 tail is a somewhat uncertain bird of passage, but in the 

 autumn of some years — notably 1900, 1903, and 1904 — has 

 been fairly plentiful. 



The Tree-Pipit has been observed occasionally in the autumn 

 both on Tresco and on St. Mary's, once on St. Martin's, and 

 twice on Bryher. It is probably often overlooked, and may be a 

 regular autumn visitor. An adult male was found dead on St. 

 Agnes early in June, 1902. The Meadow-Pipit is an abundant 

 resident. Occasionally, as in the autumn of 1899 and 1904, 

 large flocks pay the islands a passing visit. A single specimen 

 of the Tawny Pipit was shot by Pechell near Old Grimsby, 

 Tresco, on Sept. 19th, 1868. Bichards's Pipit is an occasional 

 accidental visitor, one having been killed by Pechell in October, 

 1849, and three others at the same time as the Tawny Pipit just 

 mentioned. On May 16th, 1903, a pair were watched for a con- 

 siderable time flying backwards and forwards over the marshes 

 at Porthellick Bay, near Holy Vale, St. Mary's. The only speci- 

 men of the Water-Pipit so far recorded for the county was 

 obtained by Clark at Porthellick Bay on May 17th, 1903, the 

 day after the appearance of Bichards's Pipit. The Bock-Pipit 

 is an abundant resident, very much in evidence during the 

 spring and summer months. It nests in considerable numbers 

 on nearly all the available islands, including Guthers and Bound
