Physical description Click here for a physical description Western Subalpine Warblers are small insectivore birds. Their plumage is dimorphic, i.e. males and females are different. Males have a grey head, down to the ear coverts, mantle, upperwing coverts and back. On the grey sides of the head the eyes are surrounded by red orbital rings. From the gape backwards and downwards, they have a white moutachial stripe. The front, from the chin downwards, is rusty-orange to the chest, getting paler and more greyish downwards towards the vent and undertail coverts. The flight feathers are dark-grey with thin pale edges. Females have a lighter-grey head than males, with more inconspicuous moustachial stripes. The front is mostly off-white to light grey, with a pinkish-buff wash, especially on throat along the sides and flanks. The mantle and back are brownish-grey. Their dark-grey flight feathers have faint lighter-grey edges. Both sexes have orange-brown to brown irises, a grey upper mandible and a horn-coloured lower mandible and pinkish-brown legs and feet. Juveniles have a light-grey front, greyish-brown back, and their wing feathers have bold rufous edge lining. The tertials have prominent black centres.
