“Of their habits there is little to record, these being, as far as we had opportunity of 
Judging, similar to those of Parus borealis. At that season (end of winter, April and beginning 
of May) they appeared to haunt the birch-woods in preference to the pine-regions, finding, no 
doubt, better feeding amongst the decayed stumps and loose bark of the first-named growth. 
They were very silent, and almost always intent upon the search for their food, and were seen 
in pairs on most of the occasions on which we met with them.” 
Having now ascertained that the present species is distinct from Parus borealis, all the notes 
respecting the occurrence of this species in Asia, published in the article on Parus borealis, are 
referable to the present species, and not to true P. borealis; for both Von Middendorff and 
Schrenck give short descriptions of the birds obtained by them which leave no doubt that the 
specimens obtained by them are true P. camtschatkensis. This latter species is found as far east 
as Hakodadi, in Japan, whence I have two specimens from the collection of Mr. Swinhoe, and 
am thus able to state that his Parus baikalensis is referable to P. camtschatkensis, his type from 
Lake Baikal being identical with the other specimens of this species which I have examined. 
Having also examined the other Titmice from China in the collection of Mr. Swinhoe, I find 
(curiously enough) that the Marsh-Titmouse which inhabits that country is Parus borealis; but 
the specimens in Mr. Swinhoe’s collection, four in number, all from Pekin, do not belong to the 
most decided form of that species; they more resemble specimens obtained from localities in 
Europe where Parus palustris meets Parus borealis, though, at the same time, I have no 
hesitation in referring them to the latter species. These specimens are labelled by Mr. Swinhoe 
Parus kamtschatkensis; thus the species referred to by him (P. Z.S. 1871, p. 362) under this 
name is undoubtedly Parus borealis, and not the present species. From this it is clear that 
Parus borealis has a far wider range to the east than was at first supposed, and that it has in 
Eastern Asia a more southern range than in Europe, being replaced to the north by Parus 
camtschatkensis. 
In habits the present species does not. appear to differ from Parus borealis; and I have no 
definite data respecting its nidification, in which it doubtless also agrees with that species. 
The specimen figured is an adult male from the Petchora.
