The Eagle has the longest life-span of it's species. It can live upto 70 years,
but to reach this age, the Eagle must take a hard decision.
In it's "40's" , its long and flexible talons can no longer grab prey which serves as food.
It's long and sharp Beak becomes bent.
It's old aged and heavy wings, due to their thick Feathers, become stuck to it's chest and make it difficult to fly.
Then, the eagle is left with only two options:
Die or Go through a pain ful process of change which lasts 150 days.
The process requires that the eagle fly to a mountain top and sit on it's nest.
There the eagle Knocks it's beak against a rock untill it plucks it out.
After plucking it out, the eagle will wait for a new beak to grow back and then ot will pluck out it's talons.
When it's new talons grow back, the Eagle starts plucking it's old-aged Feathers.
And after five  months, the eagle takes it's famous flight of rebirth and lives for........................30 more YearS.!
