About These Birds
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.
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.
