The Teen Years

I've been having identification problems lately: I've seen quite a few White-crowned sparrows...but they've looked a bit different from each other.  I was sure they were the same bird.  I decided to check my books. 

Aha! This is a juvenile.  The stripes on his head are brown.  Take a look at the adult I've previously blipped. Notice the difference and why I was so flummoxed?  This youngster was half in the sunlight and half in the shade, so it's not the best it could be.  But you get the idea!
