About These Birds

Dunenspecht

Der Dunenspecht ist der kleinste und am weitesten verbreitete Specht Nordamerikas. Seine geringe Größe erlaubt ihm die Nahrungssuche an dünnen Zweigen und Pflanzenstängeln, die größeren Spechten unzugänglich sind. Im Winter schließt sich der Dunenspecht häufig gemischten Vogelschwärmen an und profitiert von der erhöhten Wachsamkeit mehrerer Arten gegenüber Fressfeinden.

Kaiserpinguin

Der Kaiserpinguin ist die größte und schwerste aller Pinguinarten. Er brütet unter den härtesten Bedingungen der Erde und erträgt antarktische Wintertemperaturen von bis zu -60 °C und Windgeschwindigkeiten von 200 km/h. Männchen bebrüten das einzelne Ei etwa 65 Tage lang auf ihren Füßen unter einer Bruttasche, während sie fasten.
