Spring songbird migration is in full swing! Over the weekend, a warm front moved in, bringing flocks of warblers to our yard. The birds spent the better part of two days flitting and feasting in our birch tree, and we spent the better part of a morning and evening craning our necks to watch them. We identified six different species—most of which we had never seen in our yard before and may never see here again.

(The term “fall out” refers to the phenomenon of a frontal system temporarily stalling bird migration. In some places, thousands of birds fall out to rest and feed until air currents are more favorable.)
