Lark buntings, the Colorado state bird, are rare, but they're a little easier to see in the spring, when the so-called "troubadours of the plains" arrive in Colorado before flying south again at the beginning of fall. During the summer, they can be spotted feeding in large flocks along roadsides on the eastern plains and, in particular, in the Pawnee National Grassland in Weld County. Their coloring makes them easy to see: The males are black with a white patch on their wings, which makes them look like they're wearing tuxedos. Fancy.
