Lynton to Ilfracombe. - an exceptions to this rule,
such as the Blackbird many of whose notes closely 
resemble our Robin's, the Swallow and Sand Martin
whose voices exactly reproduce those of their American
representatives, and  the [?] and Knight's which
approach closely their allies in our country. These 
are no exceptions, however, in respect to the absence
among British birds of notes resembling those of
our Warblers and Sparrows. Dealing only with the
flight, call and alarm notes of the birds of England
and America it seems to me quite possible to
classify most of them broadly as follows: (1) Notes peculiar
to the Old World of which those of the House Sparrow
may be taken as the type. (2) Those peculiar to
the New World with those of our Yellow Warbler and
Song Sparrow (a dozen other [deleted] species in either [/deleted] American
Warblers or Sparrows would do equally well) as types.
(3) Notes common to both continents as those of
the Swallow, House & Sand Martins, [?] and
Knights. It is an interesting fact - doubtless a
mere coincidence - that the call note of the 
English Robin almost exactly reproduces that of
our Cardinal Grosbeak and the cry of the
British Swift that of our Cedar Bird. The close
resemblance which exists between the flight note
of the Green Finch and that of Loxia leucoptera 
is perhaps explainable through association with 
the Crossbills of Northern Europe.
  To return to Lynton. The House Sparrow abounds
in its shade trees & gardens but almost if not
quite for the first time since leaving Chester
