The following are all in similar timber growth, whicli 
indeed constitutes most of the wooded areas of Caithness: — 
6. Westfield; 250 pairs; fifty years established; do not 
roost in winter here. 
7. Olrig; 100 pairs; twenty years established. 
8. Castlehill; 50 pairs ; twenty years established. 
9. Barrock ; 150 pairs; thirty years established. 
And, besides the above, there are those already men- 
tioned as nesting in Thurso and Wick. 
Mr. Wm. Eeid has added the note — " Eooks have multi- 
plied in Caithness of late years, and several new rookeries 
have been established " ; one " last year," for the first time, 
at Hempriggs (Mr. W. Reid's notes, dated 1870). 
131. Corvus corax, L. Raven. 
Resident, only a few pairs breeding in certain localities 
throughout the eastern district ; most abundant in the late 
spring and autumn. Near Balnacoil there is a rock in 
which more than a hundred ravens used to roost, as late as 
1878 ; there was another rock where great numbers also used 
to roost, but this has been deserted for years, so probably 
they took to the other locality mentioned before.^ Common 
in the west, though much persecuted, but scarcely so abun- 
dant as some eight or ten years previous to 1877. Scarcer 
around Durness, though by no means approaching extinction 
in 1882; and seen occasionally by the lighthouse keepers 
at Cape Wrath, as stated in the migration schedules. 
A pretty regular crop of ravens is found annually, as 
shown in the following notes : — 
In Assynt in 1870 . 7 And in Durness in 1874 . 11 
„ 1871 . 10 „ „ 1875 . 10 
„ 1872 . 18 „ „ 1876 . 14 
„ 1873 . 19 „ „ 1877 . 14 
^ These congregations of ravens are not common in Scotland ; other localities 
known to lis where they occur, are at certain points of the Wigtownshire coast, 
and the hills of the Stewartry of Kirkcudbright.
