Appearance:

Adults black, or dark grey with big white/off-white, crescent-shaped chest patch. The light grey fringes to the flight-feathers gives the whole wing a silvery look, especially in flight. Juveniles have a more brownish base colour, with lighter scaly underparts and just a vague chest patch. The whole bird gives a more slender impression than Blackbird, and the wings are longer. Flight more determined and direct than in Blackbird.

Sound:

Alarm call a series of "chok-chok". Thicker and more resonant than Redwing. Song a primitive, plaintive series of short phrases. Often with only one or two syllables. Interspersed with eerie, higher pitched sounds, reminiscent of Song Thrush.

Appearance:

Small martin with dark brown chest-band and white throat. Upperparts dark brown, underparts white. Underside of wings dark. Juveniles with light fringes to brown feathers, and buff throat. Flight more elegant than Barn Swallow and House Martin. Often changes direction but keeps altitude. More fluttering flight than House Martin, with less gliding.

Sound:

Contact call a mono- or disyllabic "trrrrt". Similar to House Martin but more raucous and less crisp, with less rolling r's, and with stable pitch throughout. Song a primitive improvisation on the contact call. Alarm call similar to House Martin; a sharp plaintive "tseep", but somewhat purer and more drawn.
