Mr. F. N. Chasen on the 
[Ibis, 
came the flights of Books that were to populate the dirty 
acres of the plain for the winter. My diaries contain 
frequent notes concerning the entire absence of Crows from 
sundry localities during the period April to August. One of 
the largest Corvine movements was during the first few days 
of October 1917, when immense flocks of high-flying birds 
(sp. ?) passed over Orljak, but from such varied points 
that I could not name the general trend of the movement by 
the compass. 
A point worthy of notice was the unsuspiciousness of the 
wintering Crows in Macedonia. In the winter of 191G my 
duties frequently caused me long rides across the plain, and 
I often walked my horse quite through flocks of Books, 
flocks chat on occasions could almost be measured by the 
acre, without disturbing any but those birds in the direct 
path. They were certainly far more >approachable than the 
Crows in Western Europe.] 
Corvus corax. Baven. 
Often seen on the hills, but not evenly distributed. It is 
resident and usually met with in pairs, although small flocks 
of anything up to fourteen individuals were noted. The 
road leading from Orljak to Kohcan-Mah wends through 
several good places for Bavens. Several seen at Paprat in 
autumn. In the case of unsavoury meals the Ravens would 
often be at the feast before the Vultures had them located. 
Corvus cornix. Hooded Crow. 
Abundant in winter, but less numerous than the Jackdaws 
or Books. During the spring odd birds were seen about the 
hills, where I located a few nests. On 13 January a Goose 
was shot from the bank of the Struma. It fell in a very 
awkward position, just on the edge of some ice piled up 
aoainst the opposite bank. It was scarcely an hour before 
this Goose was retrieved, but when I did get it, it was 
completely spoiled by the Hooded Crows, who had pulled it 
about most audaciously. I was within thirty yards of the 
Goose from beginning to end, but in spite of this no amount 
of stone-thro wing or shouting would shift the birds. The
