SAND MARTIN. 



HIRUNDO RIP ARIA, Linnaeus. 



This bird arrives in small numbers at Tongue about the end of 

 Ai^ril. Like the last named species, they are much later of arrival 

 in the west, where I know of no large colonies, but only of a few 

 scattered pairs, breeding up and down the banks of a single burn, 

 in the extreme south-west of the county. 



TENUIROSTRES. Fam. il, CERTHIADAE. 



COMMON CEEEPEE. 



CERTHIA FAMILIARIS, Linnaeus. 



Plentiful as a species at Rosehall, and in the east, though none 

 are found in the birch-woods of the west. It is found at Tongue. 



COMMON WREN. 



TROGLODYTES PARVULUS, Koch. 



Common, and very generally distributed, even in the wilder 

 portions of the country, but commoner, without doubt, at 

 Dunrobin, Rosehall, and in other wooded or cultivated districts. 



DENTIROSTRES. Fain, i., LUSCINIIDAE. 



SEDGE WARBLER. 



ACROCEPHALUS SCHOENOBAENUS {Linnaeus). 



This species was traced to the very north of Sutherland by Mr 

 Selby. It is a common species in some suitable localities, but 

 comparatively rare in others. Mr R. I. Shearer includes the Reed 

 Warbler in his " List of Birds of Caithness." evidentl}^ a lapsus 

 jpennae, as the Sedge Warbler is omitted. 



COMMON WHITETHROAT. 



SYLVIA RUFA* (Bodd). 



I have never met with the Whitetliroat, though doubtless 

 present in limited numbers in suitable localities. Mr Selby 

 considered it of rare occurrence in 183Jt, when it was observed
