October.--There were important migrations of summer birds and partial
migrants on the 3d, 4th, and 5th, commencing simultaneously with the
passing away of adverse meteorological conditions (_see_ p. 91).
Afterwards the records indicate a complete blank until the 18th, up
to which day the weather was exceedingly unsettled, with strong winds
and gales. From the 18th to the 31st, conditions were quieter, with
north-easterly, easterly, and south-easterly winds, and under what
may be termed mildly unfavourable conditions (_see_ pp. 94 and 96),
a steady and unbroken flow of migrants was kept up; during which the
winter visitors first appeared at the stations, where, also, the
departing summer birds put in a final appearance for the season.
November.--The only movement during the month took the form of rush,
and extended from the 22d to 27th. This was, doubtless, occasioned by
the outburst and prevalence of low temperature (_see_ Meteorological
conditions, p. 100) then experienced in our Islands, causing
birds--_Turdinæ_, _Alauda arvensis_, _Vanellus vulgaris_, _Scolopax
rusticula_, _Gallinago cœlestis_, _Numenius arquatus_, and a few
_Regulus cristatus_,--which would otherwise have been contented to
remain with us, to seek more genial winter quarters.
The returns for this section of the coast again bear out the opinions
expressed in former reports,--_First_, That the main body of the
autumnal migrants reach the west coast of Wales and the south-west
coast of England--and probably Ireland, too--by way of the Isle of
Man; the north-western coast of England only receiving a comparatively
small share in these movements; _Second_, That emigrants from Ireland,
and other birds migrating _viâ_ Irish routes, strike the British
coast at the mouth of the Bristol Channel, along whose north shore it
is believed many pass. It seems probable, however, from a careful
examination of the records, that the right wing at least of these Irish
migrants extends as far south as the Land's-End stations, and those
from Land's-End to Start Point. This is made evident by the several
independent--if they may be so termed--and important movements which
are recorded in the diary, for this portion of the coast alone, under
the following dates; August 22d, September 3d, and October 24th, 25th,
and 26th, and which not only indicate the route followed, but also its
origin (Ireland), by reason of the circumscribed area affected.
_Corvus cornix_, _Plectrophanes nivalis_, _Asio accipitrinus_,
_Bernicla brenta_, _Fringilla montifringilla_, and _Passer montanus_
are again absent, or very rarely mentioned in the returns; while
_Scolopax rusticula_ and _Regulus cristatus_ were not at all frequent
during the season under consideration.
Among the rarer or more interesting species observed may be mentioned
_Agelæus phœniceus_, _Ruticilla titys_, _Procellaria leucorrhoa_,
_Stercorarius catarrhactes_, _Anas streperus_, and _Pandion haliaëtus_.
