The Immature Gull

So I learned something today about gulls,
specifically the Herring Gull, the common scavenger-type birds
frequently encountered in the coastlines of New York City.
I see them following garbage trucks up here in Inwood.
I thought this brownish bird on the left was a different sort of  gull than the common type. 

But, no.
I learned that the immature Herring Gull takes about 4 years to lose its brownish marks.
Thanks, Internet.
I watched this particular youngster walk awkwardly along the pier at Muscota Marsh.
In time, the immature gull will take on the white, grey, and black-tipped feathering of the adults.

We've all felt like the immature gull from time to time.
