FLY-CATCHER. 
209 
Beam-bird perched on some prominent twig, com- 
manding a view all round. In an instant it may be 
seen to dart, like a little shot, upon a fly, passing 
often at so great a distance, that it would quite 
escape our powers of vision ; but by no means that 
of this keen-sighted bird, for the fly is no sooner 
seen than caught, and brought back with equal rapi- 
dity to the twig on which the bird was before perched. 
The clearness of sight in birds is indeed prodigious, 
and has been calculated by an eminent naturalist, 
(Lacepede), to be nine times more extensive than 
that of the farthest-sighted man.
