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.
Vervain Hummingbird
The second smallest bird in the world (6 cm, 2-2.4 g). Endemic to Jamaica and Hispaniola. Tiny green plumage with a short bill. Nectarivore of garden flowers and forest edges. Named vervain for its preference for Stachytarpheta (vervain) flowers. Weighs less than a penny.
