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.

Rotschwanzbussard
Der Rotschwanzbussard ist der am weitesten verbreitete und häufigste Bussard Nordamerikas. Sein durchdringender Schrei ist so unverkennbar, dass er in Film und Fernsehen oft über Aufnahmen von Weißkopfseeadlern gelegt wird. Diese anpassungsfähigen Greifvögel gedeihen in vom Menschen geprägten Landschaften und sind ein vertrauter Anblick auf Masten entlang von Autobahnen.
