In all of the alphabet there are only a few letters that are difficult for me to find a picture to represent. X is one of those letters. Fortunately it is a bit easier to find a scientific name that begins with an X. Xanthocephalus xanthocephalus is the scientific name for the yellow-headed blackbird. The yellow-headed blackbird is more closely related to meadowlarks then it is other blackbirds that is why it is in its own genus Xanthocephalus instead of Agelaius or Euphagus like most other blackbirds.
The yellow-headed blackbird breeds in the western United States and up into Canada. They inhabit prairie wetlands and cat-tail marshes. The nest is cup shaped and usually attached to the vegetation. Yellow-headed blackbirds nest communally. They typically also nest with in the same habitat as red-winged blackbirds. Since the yellow-headed black birds are larger then the red-winged blackbirds they usually get the better nesting spots. Yellow-headed blackbirds migrate down to the south western United States and Mexico for the winter.
