The Brown Thrasher always arrives looking like he has been rooting around in the mud…probably because that is exactly what he has been doing!
I guess in his mind, the etiquette of washing up for dinner simply doesn’t apply to dirty beaks.
Truth be told, I like his dirty-beaked look; it adds to the rest of his “don’t mess with me” appearance.

I love his don’t-mess-with-me stance in the second photo the most. Thanks for sharing these terrific photos!
great captures Kathy!
