THE FLIGHT OF THE BIRD 145 
““Then, as I have told you before, birds are peculiarly 
liable to destruction by striking high objects. A new 
tower in a city kills many before the survivors learn to 
avoid it. The Washington Monument has caused the 
death of many little migrants; and though the number 
of its victims has decreased of late years, yet on a single 
morning in the spring of 1902 nearly 150 lifeless bodies 
were strewn around its base. 
“ Bright lights attract birds from great distances. While 
the torch in the Bartholdi Statue of Liberty in New 
York Harbor was kept lighted, the sacrifice of life it 
caused was enormous, even reaching a maximum of 
700 birds in a month. A flashing light frightens birds 
away, and a red light is avoided by them as if it were

the wanderers to destruction. Coming from any direc- 
tion, they veer around to the leeward side, and then, 
flying against the wind, dash themselves against the 
pitiless glass. 
Distance of Migration 
“The length of the migration journey varies enormously.

Carolina Wren, and Bob-white rounds out its whole 
contented life within ten miles of its birthplace. Other 
birds, for instance, the Pine Warbler and the Black-
