Toxic bird

Toxic birds are birds that use toxins to defend themselves from predators. Although no known bird actively injects or produces venom, toxic birds sequester poison from animals and plants they consume, especially poisonous insects. Species include the pitohui and ifrita birds from Papua New Guinea, the European quail, the spur-winged goose, hoopoes, the bronzewing pigeon, and the red warbler.^[1]

The pitohui, the ifrita, and the rufous or little shrikethrush all sequester batrachotoxin in their skin and feathers.^[2] The African spur-winged goose is toxic to eat as it sequesters poison in its tissues, from the blister beetles that it feeds on.^[3] European quail are also known to be toxic and are able to cause coturnism at certain stages in their migrations.
