I can't believe it's not butter
With its distinctive yellow rump, the Yellow-rumped Warbler (Setophaga coronata) is often lovingly referred to as the "butter-butt." It is one of the widest-spread of warblers. This is due to its versatility. For instance, it is the only warbler able to digest the waxes of bayberries, allowing them to enjoy life in the far northern climes of Canada. During the summer, they dine primarily on insects of all sorts. In spring, they stream northward from the south in great numbers, and are the most common warblers encountered. Once in their breeding grounds, which spread throughout Canada and Alaska, they select conifers within which they build their nests and rear their young.
