Heavily built rusty red raptor with large yellow legs and feet. When perched, the tail is longer than folded wings (Square-tailed Kite has wings extending below the tail). In flight note bulging trailing edge to wing. Tends to soar with wings back and head protruding. Extremely rare and typically limited to tropical areas near river systems in northern Australia.
