About These Birds
Coppery Thorntail
A tiny hummingbird (7-8 cm) known from very few specimens collected in Bolivia. Coppery plumage. Almost nothing known about its ecology or current status. One of the most mysterious hummingbirds; possibly rare, possibly overlooked. Further fieldwork needed.
Rubinkehlkolibri
Der Rubinkehlkolibri ist der einzige im Osten Nordamerikas brütende Kolibri. Diese winzigen Vögel schlagen mit ihren Flügeln etwa 53 Mal pro Sekunde und können rückwärts, seitwärts und sogar kurzzeitig kopfüber fliegen. Auf ihrem Zug überqueren sie den Golf von Mexiko in einem außergewöhnlichen, ununterbrochenen Flug von 800 km.
