About These Birds
Sage Grouse
The largest North American grouse (~2.1 kg), family Phasianidae, males with a spiked tail and inflatable yellow air sacs used in elaborate lek displays. Entirely dependent on sagebrush (Artemisia) ecosystems in the western United States and Canada for food and nesting. Feeds primarily on sagebrush leaves. Near Threatened; population severely declined due to widespread sagebrush habitat conversion.
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.
