A slender bird, the upper part is grey-brown, while the under part is whitish with faint dark longitudinal stripes on the breast and crown. The bird is often found sitting erect on tree branches, power lines, or fence-tops, its tail suspended but frequently twitching. It nests in gardens, parks, on the edge of forests, but frequently also on buildings. It feeds on insects and berries. It broods once or twice a year, on a dish-shaped nest that it makes from straw, small roots, moss, and animal hair 1 – 4 m above the ground in hollow trees, on wood piles, inside the walls of man-made structures, or in half-open nesting boxes.
