Mr. F. N. Cliasen on the 
[Ibis, 
Serums serinus. Serin. 
Flocks in early October at Cakirli. A few remained 
(actually in the village) at Orljak through the winter. 
Severe weather always had the effect of bringing more into 
the village, where they found shelter and food. 
Pyrrhula pyrrlmla. Bullfinch. 
A few seen in the winter, usually alone or in pairs. A 
curious feeding habit was noticed on 7 February. A male 
plucked a berry from a slender twig overhanging the water, 
while it was on the wing. The bird remained for a few 
seconds fluttering, or rather hovering, by the side of the 
berry before snatching it. The twig would have been 
scarcely stout enough to bear the weight of the bird. 
Fringilla ccelebs. Chaffinch. 
Extremely numerous in winter. The common Finch of 
many districts, in some cases outnumbering the Tree-Sparrow. 
Most of the Chaffinches withdrew from their winter haunts 
in March. The nest was not found, but a few birds, 
obviously paired, were seen through the spring. An influx 
in October. 
Fringilla montifringilla. Brambling. 
On 4 January a number were mixed with the Chaffinches 
in Orljak. The weather was severe and there was snow on 
the ground. There were also some independent flocks of 
considerable size near the river. These birds went as 
suddenly as they had appeared, and a few days later not one 
was to be seen. One or two others identified at odd times 
during the winter. 
Passer domesticns. House-Sparrow. 
Passer montanus. Tree-Sparrow. 
Both species common almost everywhere. P. montanus 
predominates in a large number of districts, and I should s&y 
is numerically superior in most parts of Macedonia. Both 
species breed freely. Although both kinds could be seen 
in mixed flocks during the day, there was a strong tendency 
to roost in specific bands. P. montanus preferred willow- 
trees for this purpose.
