About These Birds
Annakolibri
Der Annakolibri ist der häufigste Kolibri entlang der Pazifikküste und eine von nur drei Kolibriarten, die ganzjährig in den USA verweilen. Männchen zeigen spektakuläre Sturzflüge aus 40 Metern Höhe und fangen sich mit einem lauten, von den Schwanzfedern erzeugten Zwitschern ab. Nachts kann ihre Körpertemperatur nahezu auf Umgebungstemperatur absinken, um Energie zu sparen.
Purple-chested Hummingbird
A small hummingbird (8-9 cm) found in humid Pacific lowland forests from eastern Panama to western Ecuador. Males have a rich purple breast patch. Nectarivore of Chocó forest edges. Named after the German zoologist William Rosenberg.
