At a time when the northern
hemisphere enters winter and start a food source diminished during this time
that millions of birds perform an annual tradition to fly to the southern

(coastal pacific corridor) route will be from the East at bird traversed Russia
and passing through the islands of Japan and Taiwan then South Filiphina and
pulled over in the area of Sunda is great and in migration once they can fly up
to a distance of 15,000 km of travel time 50 to 70 days.
Raptor migration journey time can
fly at a time during the day and at night they are seeking a haven to relax and
rest in a place they can spend up to 15 days to find then then continue journey
back. The raptor uses an internal clock
that they have to be able to detect the location of the Sun and Earth magnet.
By using the help of a hot air they can do high flying and gliding and this can
save their energy on the way to migration to destination.
