About These Birds
Zwergsperber
The Little Sparrowhawk (<em>Accipiter minullus</em>) is one of the smallest members of the family Accipitridae (Hawks, Eagles & Kites), a compact and agile raptor found across forest habitats of sub-Saharan Africa. It occupies woodland and forest edges where its small size allows it to pursue prey through dense vegetation with great agility. Detailed plumage and behavioral descriptions of this species are limited in the available literature, though its diminutive form is characteristic of small accipiters adapted to swift aerial hunting. …
Weißkopfseeadler
Der Weißkopfseeadler ist der Nationalvogel und das Symbol der Vereinigten Staaten. Einst durch den Einsatz des Pestizids DDT gefährdet, erholte sich der Bestand bemerkenswert und wurde 2007 von der Liste der gefährdeten Arten gestrichen. Diese kraftvollen Greifvögel bauen die größten Baumhorste aller Vögel, manche mit einem Gewicht von über zwei Tonnen.
