NUTHATCH-CKOWS. 283 



white spots ; under parts white ; a yellow-white band 

 over the wings. 



Is met with both in the south and middle of Sweden, 

 and also in South Finland and Denmark, and remains in all 

 these countries throughout the year ; but is everywhere spar- 

 ingly distributed. 



Gen. Sittdj L. 



Beak straight, conical; tail even, weak, consisting of 

 twelve feathers. 



48. SITTA EUROPEA, L. Not vacka. The Nuthatch. D. F. 

 Length about 6 in. Grey-blue above, with a black 



streak through the eye; below whitish; the two middle 



tail feathers blue-grey, the rest black.

 it goes, but certainly as far as Upsala. Has only twice been

Gen. CorvuSj L. Crows. 



Bill strong, thick ; upper mandible slightly bent at the 

 top ; nostrils basal oval, generally covered by bushy feathers; 

 wings pointed, fourth feather longest ; feather covering hard 

 and fast. Mode of progression a stately walk. 



1. Oorvus. Tail moderately rounded. 



The wild nature of this country is peculiarly adapted to 

 the habits of this old-fashioned bush-ranging bird, which is 

 met with everywhere, from the very south of Scania to the 

 north of Lapland.
