About These Birds
Venezuelan Sylph
A spectacular hummingbird closely related to Long-tailed Sylph, endemic to the coastal mountains of northern Venezuela. Males have long violet-blue tail streamers. Nectarivore of cloud forest. Sometimes considered a subspecies of Long-tailed Sylph. Very limited range.
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.
