42 SKETCHES OF EUROPEAN ORNITHOLOGY. 



migrate, viz., the Fieldfare, Redwing, and Common Thrushes, as it 

 arrives in spring, and immediately resorts to the mountainous dis- 

 tricts of England and Scotland, preferring those that are the most 

 stony and barren.' Although it doubtless always breeds in the situ- 

 ations above described, it may not unfrequently be seen traversing 

 the hedgerows of uncultivated lands during its passage to and from 

 distant climates. — In general form and appearance it strictly resem- 

 bles the Blackbird (Garden Ouzel), but in its manners it is much 

 more shy and distrustful, rarely permitting itself to be approached. 

 Unlike that bird, it is not observed skulking among the bushes, &c., 

 but affects more open situationSj which doubtless renders it habitu- 

 ally cautious, as being more necessary to its safety. Its voice is 

 somewhat harsh and powerful, consisting of a few notes, which, ac- 

 cording to Mr. Selby, are not unlike those of the Missel Thrush. 

 On the continent it is distributed through most of the northern 

 countries, and is very common in Sweden, France, and Germany ; 

 indeed, with the exception of Holland, it is universally distributed 

 throughout Europe, as well as the adjacent parts of Asia and Afri- 

 ca. In all these countries it is said to be migratory ; and we may 

 easily conceive the cause of this to be a failure of a supply of food 

 in the peculiar situations it frequents, and the consequent necessity 

 of retiring to a more genial climate, where beri'ies, fruits, and in- 

 sects may be easily obtained. — The male differs from the female in 

 the greater purity and contrast of his colours. The general plu- 

 mage is black, each feather having a margin of grey ; a broad gor- 

 get of pure white extends across the chest ; the bill is blackish 

 brown at the tip and yellow at the base ; legs blackish. The plu- 

 mage of the female is more clouded with brownish-grey, the pecto- 

 ral gorget being less extensive, and tinged with dusky brown. The 

 young males closely resemble the adult female, but in young fe- 

 males the gorget is scarcely perceptible." 



IMarbled Pochard, Fuligula marmorata, — Canard raarbre, JPr. 

 An adult, rather less than the size of life, is beautifully figured. 

 Inhabits the south of Europe, especially Sardinia and the Asiatic 

 borders. — Habits un^mown ; but Temminck informs us that the 

 sexes are similar. The peculiar marbling of the plumage at once 

 distinguishes this bird. We question the propriety of classing the 

 Marbled Pochard in Fuligula, and our author appears to be of the 

 same opinion, at least judging from what he says of F. rufina, a 

 closely-allied species.
