Great Combovered Eagle

A high-flying bird which, according to Fletcher's Avian Nausea Index, is potentially capable of annoying a lot of people all at once.

Annotation

Presumably a reference to (and dig at?) the Bald Eagle. For those for whom English is not their first language, a combover is an embarrassingly terrible hairstyle worn by bald or balding men in which the hair on one side of the head is grown long and then combed over the bald area to minimize the display of baldness. (This was the simple forerunner of the comboverundersidewaysdown popularised by an American real estate developer turned politician).
