doubted, from the Teftimony of many. Bellonius 
in particular reports, that he faw them in great 
Flights palling over and re-pafling the Mediterranean 
Sea, at the Seafons and Times they vilit and retire 
from us. 
The fame Sagacity that inftmfts them to change 
Climates may aifo reafonably be thought to direct 
them, and other Birds of Paffage, to the narroweft 
Part of our Chanel, thereby to evade the Danger 
of palling a wide Seas tho’, by the many Inftances 
I have feen of Birds driven Hundreds of Miles from 
any Land, there feems not that Necellity for their 
finding the Streights of Calais , as the Ihorteft Paffage 
to our Illand, they being not unable to perform much 
longer Flights. 
There are aifo Winter Birds of Paffage, which ar- 
rive here in Autumn at the time the Summer Birds 
depart, and go away in the Spring Seafon, when 
Summer Birds return. Thefe however are but few ; 
there being only four Sorts that I know of ; viz. 
the Fieldfare, Redwing, Woodcock, and Snipe; 
which two laft I have frequently known to continue 
the Summer here, and breed; fo that the Fieldfare 
and Redwing feems to be the only Birds of Paffage 
that conftantly and unanimoufly leave us at the Ap- 
proach of Summer, retiring to more Northern Parts 
of the Continent, where they breed, and remain 
the Summer, and at the Return of Winter are driven 
foutherly from thofe frigid Climates in fearch of 
Food, which there the Ice and Snow deprives them 
of. There are many others, particularly of the Duck 
and wading Kind, that breed, and make their Sum-
