Das Amerikanische Zwergsultanshuhn hat sich mittels seiner langen Zehen die Schwimmblätter von Seerosen als Lauffläche und Nahrungsquelle erschlossen. Es nimmt nicht nur Insekten von der Oberfläche der Blätter ab, sondern wendet den Blattrand mit dem Schnabel um, hält ihn durch Darauftreten nieder und sucht die Blattunterseite nach Nahrung ab.
