18 Mr. P. J. C. McGregor on [Ibis, 



October, and tlie latest date on which Wheatears were 

 recorded is November 3, 1911. 



(I presume that the Isabelline Wheatear must occur in 

 these regions, but I am afraid that I was not on tlie look- 

 out for it and overlooked it.) 



(Enanthe xanthomelsena. Black-throated Wheatear. 



A few pairs bred regularly in some sheltered gullies near 

 the town. I never saw them earlier than April 27, and I 

 have come across newly -fledged young on the 17th of 

 August. 



Cinclus cinclus caucasicus. Caucasian Dipper. 

 On February 10, 1911, I found one in a ditch within the 

 town walls. 



Troglodytes troglodytes. Wren. 



On October 26, 1910, I observed three Wrens in a rocky 

 gully near the town. 



Muscicapa grisola. Spotted Flycatcher. 



Is common as a migrant, arriving about April 26 and 

 returning in considerable numbers between the 5th and the 

 26th of September. A certain number remain to nest in 

 the poplars in the town, and in July I have noticed fle.lg- 

 lings near my camp and at Bogliaz. The autumn migrants 

 almost invariubly made their appearance late in the afternoon 

 and remained till about 9 or 10 next morning. 



Muscicapa collaris. Collared Flycatcher. 



Arrives in small numbers about April 10, and remains to 

 breed in suitable localities. Considerable parties of young 

 birds are to be seen in the late days of July, and from that 

 time onwards the passage movement increased in intensity, 

 reaching a climax about August 7, when, in 1910, 1 recorded 

 them as *' swarming" in my camp. They were, however, 

 almost daily guests during the remainder of the month, 

 though in decreasing numbers, and September had begun 

 before the last stragglers had gone. 



They were always more abundant in the morning, and 

 they were often in company with Spotted Flycatchers.
