T h e propriety o f adding this species to the British fauna, and to the list o f Irish birds, r e s t s o n th e
authority o f A. G. More, Esq., who, in a letter addressed to Mr. R. B. Sharpe, from the Natural History
Department o f the Royal Dublin Society, says:—“ The Blue Thrush, T. cyanus, was, I believe, certainly
killed in Ireland. The specimen came to us through a member of this Society, who saw it in the hands o f
Mr. Glennon, a bird-stuffer in Dublin, who told him that it had been shot associated with some Starlings in
the county o f Meath, and had been sent to him by a Mr. Bra/wington, on the 17th o f November, 1866.
The bird was, I hear, seen in the flesh by several nuiuralists, ami has every appearance o f being a wild
specimen, the plumage being not at all frayed o r m m . Uk c many other o f the rarer visitors to Ireland,
the bird seems to have arrived late in tfn «utaran. «he* | have noneed that many birds migrate from east
it« «rearrence by no means surprising. I dare s a y your
attention may have been drawn to thi* uMMrat f o r « f migration, as mine was, by the occurrence o f the
Black Redstart in winter in Engia»t4. 1 -••c a f o r remarks on the subject in the ‘Zoologist’ for 1859.”
Quite recently, indeed since my ■■■' f>..- wpweie* for the present work was drawn, Messrs. Sharpe and
Dresser have thrown some doubt up»» th r <*<v«rary «4 the above statement: thus in the a c c o u n t o f the bird
v*‘jih tin- kindness o f Dr. Carte we have been able to examine a
specimen o f the Blue Rock-Thrush, said to have been killed in Ireland . . . . Without commenting
on the unfortunate circumstances which must have induced an example o f this species to wander so far
away from its natural habitat, and to occur in Ireland in the winter; we may state our opinion, based on
an examination of the stuffed bird itself, that it has not been mounted when fresh killed, but from a
previously prepared skin. On the other hand both Dr. Carte and Mr. A. G. More believe that the occurrence
of the bird was genuine; and we therefore record the fact as being o f interest, and exhibiting the
highest northern range o f the species in Europe.” While the specimen was in London I also availed
myself .of the opportunity to examine it, when I found it to be an adult male in rather a bad state of
preservation, and, if I recollect rightly, with one of the legs burst by the wire employed in mounting—a
circumstance which frequently occurs when a specimen is mounted from a dried skin, and which may
probably have giveu rise to the doubt iu Messrs. Sharpe and Dresser’s minds as to its being a genuine Irish
specimen. I may here remark that there is no more improbability o f the bird having been killed in Ireland
than there is o f the spotted Cuckoo occurring there, o r o f the Black Redstart in autumn in England. That
sooner or later the bird would be included in the list o f our accidental visitors there can be but little doubt,,
since it is dispersed over countries close at hand (France, Portugal, and Spain), while in those lying further
to the south and east (even in India) the bird is a common denizen.
In many respects the Blue Rock-Thrush is a bird o f great interest. Its habits are peculiar, its colouring
is unusual; and the associations connected with it are o f a pleasing character, inasmuch as by most recent
writers it is supposed to be the '* ■?]>■■■- which sitteth alone on the house-top ” o f the Holy Sciptures; and
from what I saw o f it in Malta, where : *a» frequently to be seen perched solitary on the front walls of
the flat-roofed houses, I think the supposition probably correct. During my visit to the islands composing
the Maltese group I never saw two together on the same wall, while sparrows (.Passer Mspaniolensis') were
abundant; and it must be borne in mind that one o f the earliest specific designations assigned to it, that
of solitarius, had reference to this peculiarity in its ha hits.
I have stated that the Blue Rock-Thrush is found in France, Portugal, and Spain; it also occur* in the
south of Germany, in Savoy, Egypt, Algeria, Northern Africa, and Palestine. Mr. Moggeridgc state* that
