hundred miles away, with no land but the Antilles along the 

 route to guide them. 



The time of migration is full of danger to many birds. 

 Neither sight nor sense of direction avails them against severe 

 storms. Often they are thrown far out of their course by high 

 winds, and while battling with these, many become exhausted, 

 fall into the sea and perish. Dense fogs are also dangerous to 

 birds in migration. Being unable to see their course at such 

 times, they lower their flight and come so near the earth that 

 thousands of them strike against lighthouses, tall buildings, 

 monuments, telegraph and telephone wires and dash them- 

 selves to death.
