Tetraone fuligginoso

Dendragapus fuliginosus

Grande uccello scuro simile a un pollo trovato in habitat boschivi, di solito con conifere e sottobosco arbustivo. Tipicamente visto a terra; più facile da individuare a metà estate quando femmine e pulcini frequentano i bordi delle strade e i sentieri. Quando il maschio si esibisce, arruffa le piume del collo per rivelare la pelle gialla rugosa ed emette un profondo richiamo ululante, leggermente più acuto di quello del Dusky. La femmina è più marrone e con un disegno più intricato. Si notino le grandi dimensioni e la coda relativamente lunga. Si nutre di materiale vegetale, in particolare aghi di conifere. Si distingue dal Gallo Forcello Scuro per l'areale.

Areale e habitat

Their breeding habitat is the edges of conifer and mixed forests in mountainous regions of western North America, from southeastern Alaska and Yukon south to California. Their range is closely associated with that of various conifers. They thrive in old forests because they need diverse plants and trees. Regenerated logged or burned areas also attract the sooty grouse as long as there are plenty of bushes and shrubs to nest in. The nest is a scrape on the ground concealed under a shrub or log. Grouse mountain, a mountain that acts as the peak of Vancouver, Canada gets its name from the infamous blue grouse that lives on the mountain. The first hikers that reached the top of the mountain hunted the birds so they honored them by naming the mountain after them. This name is also attributed to the large population of the sooty grouse found on the mountain.

Conservazione

Sooty grouse are experiencing some population decline from habitat loss at the southern end of their range in southern California. The status of the Sooty Grouse is now classified as at risk. Currently, the species is of low conservation concern, but if a decline in old-growth forests persists the risk of endangerment will increase.
