One of the few warblers that stays in this part of Minnesota during the summer is the yellow warbler.They breed through out much of the northern half of the US and most of Canada. During the winter they migrate as far south as Central and South America.
Yellow warblers are pretty easy to identify. While many warbler have some yellow color to them most are not as bright or yellow as the yellow warbler. This one was bathing in a small creek at the Minnesota Valley Refuge.
