1917-] Bh'Js observed at Erzernm. 25 



passage northward having begun somewhat earlier (]\Iarch 

 19). 



Aquila heliaca. Imperial Eagle. 



I seldom had the opportunity of observing this Eagle at 

 sufficiently close quarters to enable me to speak positively 

 concerning its identity, but I believe that I saw it occa- 

 sionally, except from October to Eebruary. 



Astur palumbarius. Goshawk. 



One observed on September 4, 1910. 



Accipiter nisus. Sparrow-Hawk. 



The Sparrow-Hawk is resident in small numbers through- 

 out the year, except in December aiul January, when it 

 disappears, presumably in search of less inclement regions. 

 The earliest date on which I observed it was January 23, 

 1912, and towards the end of March the increased numbers 

 seemed to indicate a migration movement ; but in autumn 

 there was a well-defined passage from the end of September 

 until the first week in November, small parties of about half a 

 dozen birds being visible. These used apparently to arrive 

 late in the afternoon, and I noted that on September 20, 

 1910, a party of six alighted at dusk on the hill-side close 

 to my camp. 



The Sparrow-Hawk, like the Kestrel, nests in the tall 

 ])oi)lars in the Armenian cemetery and in the kitchen- 

 gardms. 



Milvus migrans. Black Kite. 



A few pairs appeared to nest near the town, and in the 

 first half of April a certain number were observed on passage. 

 The autumn migration was much more noticeable, perhaps 

 on account of my being in camp at the time. On Sep- 

 tember d, 1910, a flight of about 120 individuals alighted 

 on the hill-side behind my tents at about sundown and 

 rested there for some time^ eventually moving on about 

 a quarter of a mile to a group of trees, where they perched 

 for the night. During the remainder of the month they 

 vere seen almost dailv, cither in twos and threes or singly.
