Allodola di Dunn

Identificazione

Dunn's lark is a stocky bird with a large head and broad wings. It is 14 to 15 cm long with a wingspan of 25 to 30 cm. The upperparts are pale sandy-brown with darker streaks. The underparts are whitish with some dark streaks on the breast. There is a pale stripe over the eye and a pale ring around it. Birds have dark moustachial and malar stripes and a dark mark under the eye. The short, broad tail is black below while the upperside is black with rusty-brown central feathers and pale outer feathers. The bill is large, heavy and pale pinkish or yellowish in colour. After moulting, the birds become gradually duller and the dark markings fainter as the plumage becomes more worn.<p>The song is a scratchy warbling with short whistling phrases. Males sing either from the ground or in flight, hovering 30 metres or more above the ground.
