About These Birds
Sperber
The Eurasian Sparrowhawk (<em>Accipiter nisus</em>) is a widespread and well-known raptor of the family Accipitridae (Hawks, Eagles & Kites), occurring across much of Europe and Asia. It is closely associated with forest habitats, including mixed woodland, conifer plantations, and wooded farmland where it hunts small birds with remarkable speed and agility. Detailed plumage and behavioral descriptions of this species are limited in the available literature for this record, though the species is known to display strong sexual dimorphism in size. …
Harpyie
Die Harpyie zählt zu den kraftvollsten Greifvögeln der Welt und besitzt Krallen von der Größe der Klauen eines Grizzlybären. Sie ist der Nationalvogel Panamas. Die größte Bedrohung für die Art ist die Abholzung der Wälder, da jedes Brutpaar ein weites Revier unberührten Waldes benötigt.
