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.
Beautiful Hummingbird
A small hummingbird (9-10 cm) endemic to southwestern Mexico in Guerrero and Oaxaca. Males have a magenta gorget similar to Lucifer Hummingbird. Long, decurved bill. Nectarivore of dry forest and thorn scrub. A Mexican endemic with restricted range.
