About These Birds
Gunnison Grouse
A large grouse (~1.6 kg) of family Phasianidae, closely related to Sage Grouse but smaller with longer filoplumes during lek display. Restricted to the Gunnison Basin of southwestern Colorado and a small area of Utah. Entirely dependent on intact sagebrush habitat. Endangered; one of North America's rarest birds with fewer than 5,000 individuals, threatened by habitat fragmentation and drought.
Blauer Pfau
Der Blaue Pfau ist der Nationalvogel Indiens und einer der spektakulärsten Vögel der Welt. Die riesige, über zwei Meter lange Schleppe des Pfaus wird bei aufwendigen Balzritualen gefächert und in Vibration versetzt. Trotz ihrer Größe können Pfauen kurze Strecken fliegen und übernachten in hohen Bäumen.
