same year (see Migration Reports, 1882, Newman, West, 
Newman and Co., London).^ 
30. Regulus ignicapillus (C. L. Brehm.). Fire-crested Wren. 
[A specimen recorded by St. John in the collection of Mr. 
Bantock, late keeper at Dunrobin, must, in absence of more 
complete record, be considered as doubtfully admitted.] 
31. Phylloscopus superciliosus (Gm.). Yellow-browed War- 
bler. 
32. Phylloscopus collybita (FieilL). Chiff-chaff. 
" The first specimen of this warbler recorded as having 
occurred in Caithness-shire was shot at Ulbster in July 
1861 by Mr. E. Shearer. In the autumn of the following 
year considerable numbers of the same species visited us 
for the first time in company with the willow warbler, 
so that I had frequent opportunities of observing them" 
(H. Osborne in MSS.). 
As yet probably only a passing migrant, and not a 
breeding species. 
33. Phylloscopus trochilus (i.). Willow Wren. 
A summer visitant ; extremely abundant wherever there is a 
little birch-wood. A single bush sometimes shelters a pair 
of willow wrens, but a bit of green, however tiny, seems 
necessary to their existence. A nest taken near Balnacoil 
was placed in that of a robin from which the young had 
previously flown ; it was lined with feathers and arched over. 
Appears to be a regular visitant to this county, though it has 
hitherto been overlooked (0. MSS., 1868). Not appa- 
rently noticed previous to 1862, but has much increased 
since then. Mr. Osborne mentions a pair obtained near 
Pulteneytown on May 1, 1861, and also notices several 
previous migratory flights in company with chiff-chaffs as 
occurring in the autumn of 1861.
