the noise made by the Jackdaws, which is v quite an 
achievement when one considers the latter bird’s capabilities 
in this direction. The Roller was always dominant in these 
affairs and usually the aggressor. The Jackdaws showed 
great skill in their attempts to escape from the Rollers. 
They would dart and topple about in every possible manner, 
and often double back along their own line of flight. 
Sometimes they would dive headlong into thick grass or 
into the foliage of trees. Such doings, however, were of 
little avail. The pursuing Roller would keep about a yard 
behind and forestall each caprice of the Jackdaws—even to 
the precipitous downward swoops. Later in the season, 
when the Rollers had progressed further with their domestic 
arrangements, they were not so quarrelsome. It should be 
noted that the Jackdaws had paired and settled down by the 
time that the Rollers commenced their activities, and I think 
that the valiant Daw of early spring would show a more 
determined front to the intruder. I found two nests in the 
ravine at Orljak in June. The birds showed the greatest 
craftiness in concealing their movements to and from the 
nests, which were in holes near the top of a cliff, and about 
fifty yards from the bottom of the ravine. 
Bubo bubo. Eagle-Owl. 
One remained in the vicinity of the river at Orljak for 
several days, at the beginning of January. This is the only 
personal record I have, but from all accounts I have no 
doubt that this Owl is frequently met with near Lake Doiran. 
Asio accipitrinus. Short-eared Owl. 
Seen from December to March on the Struma plain. 
Carine noctua. Little Owl. 
A common resident, and one of the most noticeable of 
Macedonian birds. This Owl is distributed over the country 
in haunts that differ widely in character. It is common on 
the Struma plain, especially in or near the villages, on the 
hills, and in the woods. I saw plenty on the outskirts of 
Salonica, and, indeed, this is one of the first birds to attract
