Although its loud, hoarse calls can often be heard echoing in the high mountain slopes it calls home, this large game bird can often prove difficult to see. Extremely well-camouflaged on rocky slopes and in boulder fields. Gray head is marked with a comma-shaped white brow and a bright orange patch of skin behind the eye. Back is brown with thick black-and-white striping and the underparts are snowy-white with thin black stripes.
