confiding and so noisy that it can scarcely escape notice. 
It was not seen in the winter months. This species is very 
partial to'the villages on the Struma plain for the purpose of 
breeding. As early as 8 March a pair showed signs of 
settling down in the mosque at Ormanli. Mating was first 
noticed during the first week in April, but most frequent 
about 19th of the month. One nest contained two eggs 
on 22 April. 
Falco vespertinus. Red-footed Falcon. 
Common in the summer, and much more numerous than 
F . subbuteo. 
[Eagles. —These birds were a prominent feature of the 
bird-life on the Struma plain—in winter especially. It was 
not unusual for every post or bare tree within vision to 
be occupied by a lumpy looking Eagle, whose head was for 
ever turned in the direction of the river, watching the Ducks 
flying uneasily up and down. I 11 severe weather in January 
1917, Eagles were particularly numerous along the banks of 
the Butkova river. I could not identify A. chrysaetus to my 
satisfaction, although I examined scores of large Raptores 
through a good telescope.] 
Aquila heliaca. Imperial Eagle. 
The most numerous Eagle. Resident. Conspicuous white 
scapulars denoted a fair proportion of adult birds. I skinned 
one bird (killed with a service bullet) and found the remains 
of a Coot in the stomach. 
Aquila clanga. Spotted Eagle. 
Small Eagles seen commonly on the plain were no doubt 
of this species, but it cannot be stated with certainty. An 
immature bird seen at close range on the hills at Karamatli 
(22 July) could have been no other. On 4 May a Spotted 
Eagle was having a great deal of trouble with a writhing 
snake which it was carrying. The snake was eventually 
dropped, but the Eagle did not descend for it again. Small 
Eagles could be seen at almost anytime on the Struma plain.
