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.
Calliope Hummingbird
A tiny hummingbird (7-8 cm), the smallest breeding bird in the United States. Males have an iridescent magenta-pink gorget. Breeds in mountain meadows of the western US and Canada. Long-distance migrant to Mexico. Named for its resemblance to the beautiful Calliope of Greek mythology.
