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.
Stockente
Die Stockente ist die Stammform der meisten Hausentenrassen und die häufigste und am weitesten verbreitete Schwimmente der Welt. Erpel zeigen aufwendige Balzrituale, darunter Kopfnicken und pfeifend-grunzende Rufe. Stockenten sind äußerst anpassungsfähig und gedeihen sowohl in der Wildnis als auch in städtischen Lebensräumen.
