NEIGHBOURHOOD OF VIENNA. 605 



very common. The Cormorant (Plialacrocorax carbo) I 

 observed for the last time on October 15th, and then I only 

 saw solitary individuals. 



A Black Stork, which is a rare bird in Lower Austria, fre- 

 quented the auen of the Danube during the latter half of 

 September, and I myself once saw it in a wood of lofty trees 

 by the side of a pool. 



I paid particular attention to the migration of the birds of 

 prey, and observed that the Sea-Eagle (Halmetus albicilla) 

 took up its position on the Danube earlier than usual, for a 

 pair of old pale yellow individuals frequented the Fischamend 

 auen almost the whole of September, and are still often to 

 be seen. The Ospreys (Pandion haliaetus) also came in 

 considerable numbers at the end of the preceding and the 

 beginning of the present month, but they have now quite 

 vanished. 



The " Stein " Eagle (Aquila fulva) was several times 

 observed in the neighbourhood of Laxenburg, but I believe 

 that there was but one bird, which hunted over a large extent 

 of country, and in the course of its wanderings often appeared 

 at the same point. One afternoon at the end of September I 

 saw it perched on a high spruce-fir in the so-called 

 Franzensremise near Laxenburg, and a few days before it 

 was noticed in the auen at Guntransdorf, where it was always 

 surrounded by Hooded Crows, Magpies, and Hawks. Soon 

 afterwards a keeper saw it sitting on a stack of straw near 

 what is known as the Weitau, not far from the village of 

 Himberg, and on the morning of the 20th I caught sight 

 of a " Stein " Eagle standing on the ground in a field near 

 Eauhenwart. 



On September 29th I saw the Lesser Spotted Eagle (Aquila 

 ncevia) at the edge of the Laxenburg Park. 



The Kites have now almost disappeared from the auen of 

 the Danube, and the migration of the Harriers is pretty nearly
