ORNITHOLOGICAL NOTES. BAL 
woods in the western vicinity of Prague, where there is a 
remarkably large stock of Blackgame. Perhaps it may be 
regarded as one of the degenerations arising from over- 
population. 
The first Swallows (Hirundo rustica) were seen flying 
about the banks of one of the arms of the Danube on April 
16th, and the following day I saw some of them in Vienna. 
Arriving in Prague on the 19th I could not, in spite of 
diligent observation, discover any Swallows, nor was it until 
the 21st that I met with some on the Moldau south of the 
city, and a few days later found them in the villages of 
Northern Bohemia, though in very small numbers. 
Up to the present date I have only once seen the Martin 
(Chelidon urbica) this year, and that was on April 16th, when 
I observed a large flock flying at a great rate up-stream along 
the bank of the Danube, near Vienna. 
This winter seems also to have affected the movements of 
the birds of prey. Several Sea-Hagles (Haliaétus albicilla) 
made their ordinary annual appearance in November, among.

November there are usually none of them to be seen in that 
region; but this year it was different, for on April 10th, as I

several times, and soon afterwards perched upon a silver 
poplar well furnished with dead branches. 
I stalked up as carefully as possible under cover of the 
wood and managed to reach the edge of a little open, within 
sixty to seventy paces of the tree. An old but very small 
male was sitting on a branch looking towards the water, 
and a perfectly enormous female was lazily resting beside
