very common. The Cormorant (Phalacrocoraz 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 (Haliaétus 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 haliaétus) 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 (Aguila 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 
ofa “Stein” Eagle standing on the ground in a field near 
Rauhenwart. 
On September 29th I saw the Lesser Spotted Eagle (Aquila 
nevia) 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
