278 Miss Baxter and Miss Rintoiil on the [Ibis^ 



Falco aesalon sesalon. The Merlin. Occurs I'egularly in 

 September and October, and there are three spring records, 

 one in March and two in May. 



Falco tinnnnculus tinnunculus. The Kestrel. A passage 

 migrant ; in spring chiefly in April, though occasionally 

 seen in March and May, and in autumn from August to 

 November. 



Phalacrocorax carbo carbo. The Cormorant. It is stated 

 that a few pairs used to breed in a cave on the island^ but 

 Mr, Evans is of opinion that this species and the Shag have 

 been confused. Cormorants, chiefly immature^ frequent the 

 island throughout the year. 



Phalacrocorax graculus graculus. The Shag. A pair 

 breed on the island, and Shags, mostly immature, may be 

 seen there all the year round. In the evenings the Shags 

 and Cormorants used to assemble on the west cliff's ; there 

 they soared in circles at varying heights, settling on the cliff's 

 for a minute as they came round, and then flinging them- 

 selves oft' and circling again. These assemblies were larger 

 and more animated when there was a strong west wind than 

 at any other time, and we noticed that the flights were 

 highest above the sea under tiiese weather conditions, pro- 

 bably on account of the updraught off" the cliffs. 



Sula bassana. The Gannet. Constantly seen passing, in 

 some years us early as January and as late as November. 

 Very occasionally one will settle on the island. 



Anser albifrons albifrons. The White-fronted Goose. 

 Tiie only lecord for the island is of an imm.ature bird on 

 27 October, 1913. "Grey Geese" are frequently recorded 

 as passing in winter, but it is impossible to say to which 

 species they belonged. 



Branta bernicla bernicla. The Brent Goose. There are 

 two records of this species in October.
