of the Island of Raasaij. 503 



Heron. Arclea cinerea. 



A heronry of small extent existed for many years at the 

 south of the island in some very tall fir-trees, but unfor- 

 tunately the birds were driven away. None were allowed 

 to be killed after 1894, with the good result that in the 

 early spring of 1896 two pairs nested in some low birch- 

 trees on the north of the property, about nine miles from the 

 old station. In 1898 these had increased to four pairs, 

 one nest being actually placed on the ground at the side of a 

 small islet in a fresh- water loch. Two more nests were added 

 in 1901 about half a mile away, also in very small birch- 

 bushes, niue feet from the ground. 



White-fronted Goose. Anser albifrons. 



The first which I observed were seven in a flock on a grassy 

 swamp, October 6th, 1896. On October 4th, 1898. eleven 

 were seen at the same place. In the beginning of October 

 1901 eight or nine were again seen. They apparently 

 only frequented this one locality, and merely remained for a 

 day or two. 



Brent-Goose. Bernicla brenta. 



Small numbers are seen on the coast nearly every autumn 

 about the middle of October ; they only remain for a short 

 time. 



Barnacle-Goose. Bernicla leucopsis. 



A few of these Geese are seen occasionally in flocks of 

 from six to twelve all through the winter ; they resort to a 

 small island, feeding on the grass. I constantly saw them 

 in 1896, 1897, and 1898, but none in 1899 or 1901. On 

 October 1 6th, 1896, I observed a large flock of about a 

 hundred Geese going south, flying in a V-shaped formation, 

 but at too great a height to be identified. Their gaggling 

 drew my attention to them, or they would never have been 

 noticed. On several other occasions I have seen Geese 

 going both south and north, but too far off to make out 

 the species. 



Bewick's Swan. Cygnus beivicki. 



On February 9th, 1900, five mature birds were in a
