Tough to find things in nature that begin with the letter X. Thank heaven for the yellow-headed blackbird, Xanthocephalus xanthocephalus. The Yellow-headed black bird is a bird that is native to the marshes and prairie wetlands of the west. During the winter they migrate down to the southwestern United States and Mexico. Even though we are not really in their range here in the eastern part of Minnesota we do occasionally get them nesting this far east. It seems that this is getting to be a more common occurrence. This is not good news for the red-winged blackbirds that live in the eastern half of North America. Since the yellow-headed blackbirds are larger they will often displace the red-winged blackbirds from prime breeding spots in locations where birds share the habitat.
