[Poisoning caused by the pyrethroid compound deltamethrin in Gould's amadines (Chloebia gouldiae). Description of a case].

Within approximately ten minutes after Gould's amadines had been returned to an aviary which had been treated with the pyrethroid compound deltamethrin, the birds showed restlessness and sat pecking between their feathers, making abrupt movements. The birds ate less and declined perceptibly. Experimental exposure gave rise to identical symptoms and there were marked differences in sensitivity between species of bird.
