The eagle has the longest life-span of its' species
It can live up to 70 years
But to reach this age, the eagle must make a hard decision.
In its' 40's
Its' long and flexible talons can no longer grab prey which serves as food.
Its' long and sharp beak becomes bent.
Its' old-aged and heavy wings, due to their thick feathers,

The process requires that the eagle fly to a mountain top and sit on its' nest.

After plucking it out, the eagle will wait for a new beak to grow back;
and then it will pluck out its' talons.
When its' new talons grow back, the eagle starts plucking its' old-aged feathers.
And after five months, the eagle takes its' famous flight of rebirth and lives for ...
30 more years
