WRYNECK — FLYCATCHERS. 109 
it has shown near half the species that were ever known in Great 
Britain.* 
On a retrospect, I observe that my long letter carries with it a 
quaint and magisterial air, and is very sententious ; but when I 
recollect that you requested stricture and anecdote, I hope you 
will pardon the didactic manner for the sake of the information 
it may happen to contain. 
LETOER XLI. To T. PENNANT, Esq. 
It is matter of curious enquiry to trace out how those species of 
soft-billed birds, that continue with us the winter through, subsist 
during the dead months. The imbecility of birds seems not to 
be the only reason why they shun 
the rigour of our winters ; for the 
robust wryneck (so much resembling 
the hardy race of wood-peckers) 
migrates, while the feeble little 
golden-crowned wren, that shadow 
of a bird, braves our severest frosts 
without availing himself of houses 
or villages, to which most of our win- w ry neck . 
ter birds crowd in distressful seasons, while this keeps aloof in 
annually and invariably visited the spot, curiosity prompted me to try an experiment, which lef 
the matter out of doubt. When an opportunity offered, I took the female, cut off the extremity 
of the upper mandible of the bill, and with a knife made several perspicuous marks on its claws < 
this done, I set her at liberty. The succeeding spring the 
same bird returned, with the distinguishing marks 1 had 
given it, which was at once satisfactory and conclusive.^^ 
The following will show the attachment of the pied fly 
catcher of authors (though this bird should range in a 
separate genus) to the place it has selected for nidifica- 
tion, which fact came immediately under my own ob- 
servation. A pair of this species took up their abode in a 
garden near my residence, where, by the way, they ar- 
rived so early as in the first week in April. Their first 
nest was robbed by a boy, and another was soon built in 
the same situation (against the ivied trunk of an old 
poplar), and four eggs laid; these were destroyed by a snake; and a third nest was actually 
constructed on the top of the last, which, with three eggs in it, and the broken egg-shells of the 
last adhering to the bottom, was brought to me as a curiosity, and not a little to my dissatisfac- 
tion. I had it replaced, as well as could be done, in about a couple of hours after it had been 
removed, hoping that after all the female would perhaps sit ; but so much persecution had at 
length driven the unfortunate pair from the place, and they were not seen afterwards. This 
species is very rare in the south of England, and was unknown to Mr. White. It moults its 
clothing plumage twice in the year. — Ed.
