Halsband-Waldsänger

Bestimmung

The collared whitestart is around 13 centimetres (5 in) in length with a weight of 10.5 grams (0.4 oz). It has a chestnut crown bordered with black, and a black forehead. The rest of the upper parts are slaty black, and the tail is black with white edges, hence the bird's name: "start" is an old English word for "tail". The face and underparts are bright yellow, with a black band across the breast.<p>The sexes are similar, but young birds are duller, with a browner back, weakly yellow underparts, and the head entirely slate-coloured, with no yellow on the face or red on the crown.[citation needed]

Resident species

Verhalten

The call is a sharp pit, and the song is a mixture of slurred whistles, warbles and trills.<p>The collared whitestart feeds on insects,[citation needed] frequently fanning its striking tail as it pursues its prey. It will join mixed feeding flocks, and will follow cattle and occasionally humans for the insects they flush.<p>The roofed nest has a round side entrance and is built on the ground or a steep bank, hidden amongst rocks, tufts of grass or under a fallen log. It is constructed from strips of bark, plant fibres, leaves, and grass. From March to May, the female will lay 2 or 3 white or cream eggs that are speckled with fine brown spots. Incubation lasts about two weeks, but other nesting details are largely unknown.
