814 Birds. 



I have grouped our birds into several divisions, deduced from their 

 habits, as follows : — 



1. Land birds truly indigenous, remaining the whole year with us. 



2. Land birds remaining with us during the summer months, nest- 

 ling here, but leaving in winter. 



3. Land birds of regular double passage through the country, but 

 which do not remain and nestle with us. 



4. Land birds sojourning with us during the winter and leaving us 

 in spring. 



5. Land birds of rare or occasional appearance in Belgium. 



6. Water birds, regular visitants in summer or winter, or on their 

 double passage in spring and autumn. 



7. Water birds of accidental occurrence. 



Division I. 



The Kestril, Falco Tinnunculus. Common everywhere. 



The Sparrow-hawk, Astur Nisus. Equally common. 



The common Buzzard, Buteo vulgaris. Common. Many arrive 

 in flocks in the autumn at the same time as the fire-crested Regulus 

 {Regulus ignicapillus) and the thrushes. A few build in our exten- 

 sive forests. 



The marsh Harrier, Circus rufus. Common in the extensive 

 marshes of Campine, in the province of Antwerp, where it nestles. 

 Seldom found elsewhere, except on the sea-shore in winter. 



The little Owl, Noctua Passerina. Common in woods and orchards. 



The Eagle Owl, Bubo maximus. Found on the rocky banks of the 

 Meuse and Ourthe, where it builds. Very scarce in the forests of 

 central Belgium. 



The long-eared Owl, Otus vulgaris. Common in the woods in 

 summer and fields in winter. 



The barn Owl, Strix Jiammea. Common everywhere. 



The great grey Shrike, Lanius Excubitor. Local. Our scarcest 

 species of shrike, and the only one which remains through the winter. 



The Magpie, Pica caudata. Very common. 



The Jay, Garrulus glandarius. Common, living in small commu- 

 nities of from six to ten individuals. Numerous flocks of this bird 

 are seen in October, which apparently come from other climates. 



The Jackdaw, Corrus Monedula. Very common in our towns, 

 where it nestles, as it also docs in the fissures of rocks. 



The carrion Crow, Corvus Corona. Generally distributed, but not 

 common. Solitary.
