Starlings: Feathers and moulting

I love feeding wild birds in my garden, we have a great variety of different species and one of my favourites are the Starlings.  

We have a family of Starlings that come to the garden to feed and their antics are very amusing as they strut around and squabble amongst themselves over the food. But I have often wondered why they all look so different from each other.  I guessed it was because some of them were youngsters and others adult birds.

I come across this interesting article that explains all about why the Starlings can sometimes look so different from each other:  

When young starlings leave the nest, they're brown all over.

You've probably seen them chasing and pestering their hard-pressed parents, and heard them squawking for food.

Because starlings sometimes have two broods in one breeding season, you'll see starlings of different ages and varying appearances.
