hut if it docs not succeed in finding one it builds a new nest, 

 of ratlier small size, which being used for many subsequent 

 years grows by-and-by into a very large " horst/^ 



MiLVUS MIGRANS (Bodd.). 



Commoner than the former in watery districts, especially 

 near the Frische Haff, in the districts of Johannisburg, 

 Sensburg, Allenstein, Lotzen, and others. Returns at the 

 end of March or in April. The breeding-time varies much, 

 but the eggs are generally laid much later than those of 

 Milvus milvus. This species, as well as the last-named, is 

 extremely fond of lining the nest with coloured rags and 

 papers, often not in the best and cleanest condition. 



BUTEO BUTEO (L.) . 



The Buzzard is extremely common. I have found full 

 clutches of eggs at the end of March, but generally they are 

 not full before April. It seems likely that Buteo desertorum 

 occurs as an accidental straggler, but supposed specimens 

 of it should always be examined by an experienced ornitho- 

 logist. 



Archiruteo lagopus (Briinn.). 



Very numerous from October to April, especially in more 

 open districts. Seems to avoid the interior of large forests. 

 This bird is a Buzzard, and by no means an Eagle. All its 

 movements, its bill and feet, are those of a true Buzzard. 

 Even at a distance when gliding through the air it can be 

 recognized as a Buzzard by the wings being held above 

 the horizontal line. 



IlALIAiiTUS ALBICILLA (L.). 



Often seen on the coasts in winter, but also still breeds 

 occasionally. 



AqUILA CHRYSAiiTUS (L.). 



Often shot in wintei', rarely in summer. There can be little 

 doubt that even at the present day a few pairs breed here and 

 there in the large forests of the eastern parts of the province, 

 but it is everywhere vigorously persecuted by the forester's gun. 



Aquila pomarina, Brehm. 



As regards the name of this Eagle, I think that " Jicevia,"
