Imidacloprid is highly toxic to four bird species: Japanese quail, house sparrow, canary, and pigeon. The acute oral LD50 for Japanese quail ("Coturnix coturnix") is 31 mg a.i./kg bw with a NOAEL = 3.1 mg a.i./kg. The acute oral LD50 for house sparrow ("Passer domesticus") is 41 mg a.i./kg bw with a NOAEL = 3 mg a.i./kg and a NOAEL = 6 mg a.i./kg. The LD50s for pigeon ("Columba livia") and canary ("Serinus canaria") are 25–50 mg a.i./kg. Mallard ducks are more resistant to the effects of imidacloprid with a 5-day dietary LC50 of &gt; 4,797 ppm. The NOAEC for body weight and feed consumption is 69 mg a.i./kg diet. Reproductive studies with mallard ducks showed eggshell thinning at 240 mg a.i./kg diet.
