Colonies show annual cycling. New nests are generally founded during spring and early summer by a single queen, though
Black-faced woodswallow cessation of woodswallow decline.Storm-burning has produced a more open vegetation structure, which is beneficial for insect feeding and nesting by the woodswallows. Storm-burning is therefore thought to be essential for persistence of black-faced woodswallow habitat in the Cape York Peninsula. This also assists golden-shouldered parrot conservation by reducing their predation risk. Black-faced woodswallow The black-faced woodswallow ("Artamus cinereus") is a woodswallow. It is long.
