Butter Butt

The readership has been down on the last couple of posts, so I was hoping that spicing up the title a bit might increase the traffic.  But, it is also a fact that “Butter Butt” is a recognized optional term to refer to the Yellow-rumped Warbler.  We had two of them having a little dispute at the suet feeder this afternoon, and what caught my attention was their ability to flash this yellow butt at will. You don’t always get to see this yellow butt, and apparently they have some control over whether you do or not.
