OF THE NETHERLANDS.

either with beangeese or pink-footed geese; I have killed 

 them at the same shot. But pink-footed geese and bean- 

 geese are not found together, according to my somewhat 

 extensive experience, I have killed a thousand grey geese 

 in my time. The pink-footed geese feed by day in the 

 surrounding islands of Zeeland and assemble by night on 

 the Scholleman shoal, on the outside of the Veeregat. The 

 beangeese prefer the island marshes farther up the estuary. 

 In moonlight nights they will sometimes remain all night 

 in land. The lesser white-fronted goose *) I have never 

 recognised. The brent goose 2 ) does not occur here, except in 

 severe frost; it is common in the Brouwershavengat. The 

 bernacle goose 3 ) is common on the Krammensche Slikken, 

 but only comes here in frost. On 21 January 1903 I killed 

 30 bernacles here at one shot. But in mild winters I don't 

 see them. The red-breasted goose 4 ) has got once on the 

 Dortsman sand near Stavenisse in company with bernacles 

 by a friend of mine; this would be twenty years ago." 



VULTURIDAE. 



67. Gyps fulvus (Gmelin). [Vale gier]. 



We possess no specimen killed in our country. This 

 species has twice occurred in the Netherlands, once in the 

 province of Gelderland and once, in June 1904, in Noord- 

 Brabant (Snouckaert, Tijdschr. Ned. Dierk. Ver. X, 1908, 

 p. 211). 



Falconidae. 



68. Circus aeruginosus (L.). [Bruine kuikendief], 



20 specimens. Of this species, in the watery places of 

 our country a common bird of prey, we possess a fine 

 series of stuffed specimens, among which are interesting 

 two young birds, which have chin, throat, bastard- wing, 



1) Anser erythropus. 2) Branla bemicla. 



3) Brant a leucopsis. 4) Brant a ruficollis.
