and the most uniform in colour, and the
finest flier. It soars and floats confidently near cliffs, using
the upcurrents expertly, often sweeping backwards and forwards

and turning at the end of each traverse. It is often accompanied by cliff, around high peaks, or over water; agile, gliding
smaller, less accomplished House Martins during these flights. with few quick wingbeats, fast turns.
VOICE Short, high, metallic clicking notes, dry tshirr; TAIL SPOTS
