Rotschenkelsperber
The Rufous-thighed Hawk, <em>Accipiter erythronemius</em>, is a member of the family Accipitridae (Hawks, Eagles & Kites), a group comprising a wide range of diurnal raptors.

Weißkopfseeadler
Der Weißkopfseeadler ist der Nationalvogel und das Symbol der Vereinigten Staaten.

Diese kraftvollen Greifvögel bauen die größten Baumhorste aller Vögel, manche mit einem Gewicht von über zwei Tonnen.
