Home -
returning ; --
used specifically of carrier pigeons .
[
1913 Webster ]
{
Homing pigeon },
any pigeon trained to return home from a distance .
Also called {
carrier pigeon }.
Most are bred from the domestic pigeon {
Columba livia }.
Homing pigeons are used for sending back messages or for flying races .
By carrying the birds away and releasing them at gradually increasing distances from home ,
they may be trained to return with more or less certainty and promptness from distances up to four or five hundred miles .
The birds typically do not stop on their way home ,
and may average as much as 60 miles per hour on their return trip .
If the distance is increased much beyond 400 miles ,
the birds are unable to cover it without stopping for a prolonged rest ,
and their return becomes doubtful .
The record for returnig from a distance is close to 1 ,
200 miles .
Homing pigeons are not bred for fancy points or special colors ,
but for strength ,
speed ,
endurance ,
and intelligence or homing instinct .
Although used since ancient times ,
homing pigeons have been largely displaced for practical purposes by radio and electronic communications ,
but they are still used in some special situations at the end of the 20th century .
They were used in military operations as recently as in World War II .
