INTRODUCTION 
have been tempted to the earth for a brief rest. ‘Then 
there is the matter of observing the times of arrival and 
departure of the many migratory species that visit London 
regularly, either to breed or to spend the winter ; also 
the numerous local movements of birds that are more 
or less resident within our limits. In fact, London, 
so far as its bird-life is concerned, is a self-contained 
centre in many respects, and well worthy of systematic 
observation. ‘The gradual extension of range of certain 
species within the Metropolis is another point of ex- 
ceptional interest, the various favourable or unfavourable 
influences aiding or checking expansion well repaying 
careful and intelligent study. ‘The distribution of many 
birds within our radius is as yet very imperfectly known. 
The magnificent parks and open spaces, the many 
squares and gardens, the delightfully rural suburbs, 
must ever prove increasingly attractive haunts for birds. 
The waters are equally charming and alluring. ‘The 
care that is bestowed upon these places, the way they 
are so constantly watched and guarded and their charms 
preserved, all favour and encourage bird-life ; and if a 
little greater vigilance could be shown in exterminating 
rats and keeping cats (which should be shot at sight) 
outside these beautiful spots, there seems to be no end 
to the possibilities regarding birds that might be induced 
to take up their quarters within London’s limits. I am, 
however, utterly opposed to the suggestions that have 
been made with respect to the introduction of exotic 
species. Our own avifauna can supply every need; 
and a little judicious management would, I am convinced, 
induce many of our gayest and most charming birds to 
take up their permanent residence in many of these 
places. In some of the parks small aviaries have been 
established, and it seems ungenerous to write a word 
against them. I, however, am pleading for wild birds 
alone. We cannot have too many in the Metropolis,
