About These Birds
Buff-bellied Hummingbird
A medium-sized hummingbird (10-11 cm) found from southern Texas through eastern Mexico to Belize and Guatemala. Green upperparts, buff-orange belly, and red bill with dark tip. Nectarivore of gardens, citrus groves, and forest edges. Common at Texas Gulf Coast feeders.
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.
