THE BIRDS OF SCILLY. 245 



starts. In November, 1903, there were several pairs, with a 

 number of Goldcrests, at Tresco, among the pines between the 

 garden and the monument. Two specimens of the Yellow- 

 browed Warbler were shot on St. Martin's Common by Pechell 

 in October, 1867. One was too badly mutilated for preservation, 

 but the other was kept as an immature Firecrest, and was not 

 identified till 1890. On Oct. 1st, 1905, an adult male was 

 obtained at Tresco by David Smith, who knocked it down with a 

 stick as it flew out of a hedge. The Chiffchaff is a common 

 visitor to Tresco and St. Mary's every autumn, and is occasion- 

 ally seen on St. Martin's. It has been noticed several times at 

 Tresco in November and December, and frequently heard in 

 song in January and February ; so that it is probable a few 

 remain most years during the winter. Eodd, in 1863, speaks of 

 a pair that frequented a corner of the Abbey Garden from the 

 middle of November till the end of December. In January, 

 1904, several were in song among the Goldcrests, and David 

 Smith says that Chiffchaffs had been there continuously from 

 the 4th of November. The Willow-Wren has been occasionally 

 noticed on autumn migration, for the most part singly, but in 

 the first week in October, 1903, it was fairly common among 

 some gorse near Holy Vale, St. Mary's. On Nov. 22nd, 1904, 

 two were seen and heard in the Abbey Gardens, Tresco. The 

 Wood- Wren was occasionally observed by Pechell and E,odd in 

 the autumn, for the most part early in September, but once on 

 Nov. 8th. Since 1870 it has evidently been overlooked. It is 

 probably at least an occasional visitor in the spring, for in May, 

 1903, several were seen and heard among the trees near the 

 duck-pond at Tresco. The Pieed-Warbler was obtained in 

 September, 1849, in the autumn of 1852, in October, 1864, in 

 September, 1868, and in the autumn of 1871. Then, probably 

 from lack of observers, there is no further autumn record till 

 Oct. 6th, 1903, when it was seen on St. Mary's below Holy Vale. 

 On April 11th, 1904, there were several in song by the Long 

 Pool, Tresco ; so that, like the Wood- and Willow- Wrens, it is 

 X^robably at least a casual spring as well as autumn bird of 

 passage. The Sedge-Warbler is a common summer migrant, 

 breeding freely on Tresco. The Grasshopper- Warbler was heard 

 by the Eev. H. D. Astley on Tresco on May 12th, 1901, and two
