A small, graceful and elegant bird which appears in a variety of plumages, depending on whether it is a breeding or non-breeding male or female. Generally the male has a grey back, darker wings with a black mask, buff throat and white belly with the characteristic inverted black “T” against white background on the tail, visible in flight. It is found in open mountainous areas, with scrub and stony areas, where it feeds on insects taken on the ground or on short aerial sallies. In Extremadura it nests on the high altitudes in the north, whereas on passage it can be found almost anywhere.
