Fluffel Butts!

Spring is back. The medicinal herbs are leafing out next to the cabin and the deep thrumming of the humming birds had returned. 
On a side note does anyone else have a chest cavity that resonates with humming bird wingbeats? Just me? 
Well when we think of our feathered friends we think of their delicate but powerful pinions or their gleaming red neck feathers. 
BUT
But did you notice? They also have little white butt floofs behind their tiny footsies.
