VISITANTS, &¢c. OF THE COAST. 321 
as before named ; in addition to which, these do not 
confine themselves to one abode, and are moreover 
observed to affect znland rocks equally with shores, 
their appetites are not limited to shore productions; 
and though the Chough is in some other countries 
an inland bird, it is not so in England, save 
through accident or necessity. The Raven at times 
builds on our cliffs. The Crow is noticed very fre- 
quently in autumn and winter, examining the 
rejectamenta of the tide. The King-fisher migrates 
partially to the sea-side in October, and those 
which are found there remain till spring. This is 
another instance of diversity of action in individuals 
of one species according to situation. Itis certainly 
an ordination of Nature, to allow of more extensive 
dispersion of the whole of the species during the 
season of greatest want, for by this arrangement 
of their appetites the removal of some portion of 
the species to the estuaries and coasts permits a 
very general though very slight change in the posi- 
tion of all the members of the kind, giving to each a 
more extensive range for capture of prey during the 
time of necessity. Mr. Knapp observes that the 
universality of the Robin, that is to say its general 
dispersion, is remarkable. This is confirmed by my 
notice of it, though rarely, on the furze of our cliffs, 
and in copses at our embouchures. How remarkably 
does the history of one species differ from that of 
another when thoroughly investigated, and how 
evident is it that the completion of these histories 
is essential to the unravelling of those various plans 
instituted by the Creator for the perfection of his 
wondrous scheme of nature! There is one of the 
Gallinaceous birds an occupant of the shores, 
namely the Rock Dove, which builds sparingly in 
the caves. 
We calculate that there are fifty-six Waders be- 
longing to South Devon, and since twenty-two of
