1. Pinnated Bittern Botaurus pinnatus, Usumacinta Marshes, Tabasco/Campeche, Mexico, May 6, 2002.  Note the barring on the sides of the neck, which is quite different to the striped and streaked neck of American Bittern B. lentiginosus.  For comparison, an image of an American Bittern appears below.
