86 THE MEANING OF EVOLUTION 
borhood that there is growing to be a new race of 
birds who lack the fear of man their ancestors justly 
had. Under these conditions the wild birds, which 
for a while we believed to have been completely driven 
out by the sparrow, are rapidly returning to our vil- 
lages and towns, and we have many more robins and 
catbirds, wrens and flickers than we had ten years ago. 
We have seen the worst of the English sparrow; he 
has now found his equilibrium.
