Why some birds are black, some are white and some are colourful ??

 In ancient times, all the birds were white in colour.

Birds were getting bored by watching each other 's face.

They had decided to meet the God and ask him to give them different colours .

All the birds went near God and asked him to give them other colours than white.

God agreed and asked the birds to choose the colours they want.

Parrot came forward and said it want its full body in green colour but its beak in red colour.

God agreed and parrot has changed.

After getting transformed, parrot flew back to its house.  

There he saw Crow, Nightingale, Goose and Swan all sitting together.

Parrot saw them and said  " What are you people doing here ??  God is giving requested colours to birds.  Hurry up  !!!!  "

Listening to that, Crow and Nightingale rushed to the spot whereas Goose and Swan didn't take the trouble to rush.

Both of them remained at their place.

When Crow and Nightingale reached, God was awarding the peacock its  desired colors.

Peacock had asked for different colours to its body.

After getting the colours,  peacock was looking beautiful.

Crow and  Nightingale were watching the transformation of peacock.

Both of them urged God to give them all the colour mixed together  !!!

God cautioned them asking  Are they sure ??

Crow and Nightingale together said  YES  !!!!

God allocated them the colour they want, mixure of each and every colour......

Which is   BLACK   !!!!

But GOOSE and SWAN  didn't opted for any colour.

That's why Goose and Swan remained in white colour  !!!
