Mr. F. N. Chasen on the 
[Ibis, 
Micropus apus. Swift. 
Seven at Ormanli, 22 May. They stayed about two hours. 
Not seen again till August. On 21 August some flocks 
appeared in company with Martins and were evidently on 
passage. 
Caprimulgus europaeus. Nightjar. 
28 May. On Struma plain in September. At Salonica 
in October. Two eggs found by a friend about last week 
in June on the hills near Grramatna. 
Merops apiaster. Bee-eater. 
Common in summer. Present 4 May in pairs, and 19 Sep¬ 
tember. One of the commonest sounds on the Struma plain 
in summer is the strange cry of the Bee-eater. I was never 
fortunate enough to find a nest myself, but had eggs brought 
to me from a native cemetery. Major Sladen tells me that 
he has found them breeding near Janis and Dudular in holes 
in the ravines. 
Upupa epops. Hoopoe. 
Common in summer. In the spring of 1917 I was not in 
a favourable position to observe, and the first Hoopoe was 
not seen till 10 April. In 1918 six were seen, 3 April. Still 
numerous, 19 September. The Hoopoes were very shy birds, 
but their preference for particular localities offered oppor¬ 
tunities for observation. One or two could usually be found 
in the dense foliage oft a line of willows fringing a small 
stream near the Struma. It was quite useless to try to stalk 
these birds at midday. They were most vivacious, and would 
fly from tree to tree forbidding a close approach. They 
were seen under the most favourable conditions on the hills, 
but even there their solitary, shy habits were well marked. 
I usually contented myself with listening to their peculiar 
voice. The call of the Hoopoe is a clear “ coo-coo<” or 
“ coo-coo-coo” In tone it is between the monotonous 
cooing of the Doves and the clear penetrating voice of the 
Cuckoo, and with both these it might be very well confused. 
Unlike the note of the Dove, in which the last syllable is
