Eield-work. 

 Xo special work in the ornithology of Clare Island nor of the west 

 coast had heen done before our survey, except by the light -keepers for 

 Mr. P. M. Barrington : their schedules have been tabulated and, being used 

 with care under his correction, hare yielded information as to winter visitors 

 and migrations. Messrs. "Williams lv Son, who have for many years received 

 specimens from all parts of the district, have placed their records at our 

 disposal. 



Many notices have been written in the Zoologist, Irish Wativralist, and Field 

 about the birds of Achill and the Mullet, and these go to confirm our Clare 

 Island observations and fill up gaps in our knowledge of the winter visitors 

 and passing migrants, sucb as our limited work could not embrace. The visits 

 of ornithologists in the Survey were as follows : — 

 G-. E. H. Barrett-Hamilton— 9tk-13th April. 1909 (Clare Island). 

 R M. Barrington— 25th-29th March, 1911 (Clare Island). 

 N. H. Foster— 15th-19ih May, 1909 (Clare Island): 18th-21st May. 1909 



(Louisburgh district I. 

 „ 16th-23rd June, 1910 (Belclare district, Clew Bay islands). 

 C. Lindner— 17th-20th June, 1910 (Clare Island): 20th-23rd June, 1910 



(Belclare, Clew Bay . 

 12th-26th July, 1911 (Mullet, Inishkea. Duvillaun, Clare Island, 



Inishturk. Inishbofin). 

 C. J. Patten — 25th-30th March, lsi-14th July, 10th-29th September, 



29th-31st December, 1910; 2nd-7th July, 1911 Clare Island ). 

 R. J. Ussher — Travelled with Lindner, and has repeatedly visited the Mullet, 



Achill, Inishbofin, and most of the islands from the Mullet and 



Inishkea to Slyne Head. 



Barrington collected about thirty-two skins: Patten about fifty, with 

 specimens in spirit, and he took man}" photographs of birds in their haunts 

 and nesting-sites, and was the only ornithologist who visited the island in 

 winter. He made the land-birds his special study. 



B. LI. Praeger has contributed various notes, especially on The Bills, visited 

 with Welch on 21st June, 1910. 



Use has been made of schedules kindly filled by G. Wallace for Belmullet, 

 Alexander "Williams for Achill Sound, B. B. Sheridan, assisted by his father. 

 J. E. Sheridan, for Achill Island, J. J. McCabe for Clare Island, and 

 W. H. Good for "Westport ; some of these have been compared with schedules 

 filled by the same observers twenty years ago. Warren's hie-long observations 

 on the Isorth Mayo coast have been consulted, as well as those of others, e.g., 

 Pike for Achill thirty years ago, iJr. Burkitt for Belmullet.
