234 PROCEEDINGS OF THE 



CHIMNEY SWALLOW. 



HIRUNDO RUSTICA, L. 87. 



Apparently still continuing to decrease, at least at one locality 

 in the west. Cold, backward springs may account for this. 



HOUSE MARTIN. 



HIRUNDO URBICA, L. 87. 



Mr Mackenzie writes : — " Not a House Martin is to be seen 

 about Dornoch, but there is a numerous colony in the quarry or 

 pit near the railway bridge over the Golspie Burn." In the west 

 it has, for some years back, been becoming rarer and rarer; indeed, 

 in 1876, only one pair was known to frequent the houses at 

 Inchnadamph, while the rock-colony has entirely disappeared. 



SAND MARTIN. 



HIRUNDO RIP ARIA, L. 88. 



It is perhaps worthy of remark, in connection with the evident 

 decrease of some migrants in the west, that at the localities 

 indicated in my former paper, where I had met with a few pairs 

 of this species, I did not see a single bird this year, although I 

 visited, or was fishing in the neighbourhood, on four different 

 occasions. Actual decrease or disappearance, however, I do not 

 hold as lormed by such imperfect negative evidence. 



COMMON WREN. 



TROGLODYTES PARVULUS, Koch. 88. 



Common about the wooded slopes of the river Inver, and 

 noticed also close to the falls on the Kirkaifi: river. 



"O 



SEDGE WARBLER. 



A CROCEPHA L US SCHOENOBA ENUS, L. 88. 



Mr Mackenzie says not above two or three pairs are usually 

 seen near Dornoch, where, however, he has taken the eggs. In 

 the west I observed a pair on the islands of Loch Awe, where I 

 have also met with them on former occasions. They are decidedly 

 local.
