COMMON WHITETHROAT. 



SYLVIA RUFA [Bodd.) 88. 



Only one nest has been obtained at Dornoch by Mr T. 

 Mackenzie. There are eggs in the Museum at Dunrobin. 



WILLOW WARBLER. 



PHYLLOSCOPUS TROCHILUS {L.) 89. 



Abundant in the west. It is difficult, I fancy, to judge of the 

 increase or decrease of this species ; but the latter I would deem 

 unlikely, although Mr Crawford seems to consider that they are 

 scarcer in his district. Possibly, as woods increase in height and 

 acreage, and in these late cold ungenial springs, the tiny warblers 

 may desert the more exposed situations on the liill-sides, and seek 

 the better shelter to be found in the plantations. This year I 

 certainly did not notice this species as common in the situations 

 where I used to find them — on the bare hill-side, " where only a 

 single stunted willow or alder, or birch-bush grows " ; but I found 

 them quite as abundantly as formerly in the larger birch-woods, 

 and in the plantations along the river Inver, etc. 



GOLDEN-CRESTED REGULUS. 



REG VL US CRISTA T US, Koch. 89. 



Mr Crawford reports a decrease in the numbers of this species 

 in the Tongue district. In many other localities, I have noticed, 

 or fancied I have noticed, a fluctuation in the Gold-crest population, 

 many more birds frequenting their breeding haunts in one year 

 than in another. 



Obs. A Wood Warbler (Ph. s'lbilairix, Bechst.) is reported to 

 have been heard at Kildonan in May 1876 (aiict. Lord Clifton — 

 " Zoologist," 1876, p. 5122), but, as an addition to our list, should 

 be taken with reservation, although again recorded as occurring 

 even further to the north (Caithness — " Zoologist," 1876, p. 5164). 

 It certainly does not occur commonly in the inland glens of West 

 Sutherland; indeed, as far as my experience goes, it does not occur 

 there at all. If to be found anywhere in the west, it may be looked 

 for in the sheltered glens near the coast, in such localities, for instance,
