296 THE STRUCTURE AND LIFE OF BIRDS cH.x 
one bird, the House-sparrow, who is always at home 
amid the bustle of human life, and who, if England 
were to become one big city, would out-do Sir Boyle 
Roche’s famous bird and be, not in two, but in all 
places at once. Happily he is not the only bird 
which takes to town life. In Germany there is the 
Stork, and in London we have the Domestic Pigeon, 
the descendant of the Rock-dove, at Westminster, 
at the National Gallery, at the British Museum, at 
Liverpool Street Station, and many other places. 
And in Regent’s Park in January I have heard the 
Thrush and the Robin singing in a thick and choking 
London fog. There are a great many birds that 
will live happily and without fear amid the noise of 
human life, or in a comparatively quiet town-garden 
or park, where, however much they may be looked at, 
they are free from actual molestation. Even the 
Wood-pigeon is now a Londoner. 
BOOKS ON THE SUBJECT. 
Facts bearing on this question will be found in almost all 
books on the natural history of birds. See Mr. Hudson’s Bzrds 
in a Village.
