Birds cyanide poisoning

Bird s foot trefoil Lotus corniculatus Cyanide poisoning, convulsions, paralysis, coma, death... 

The lethal effect from cyanide poisoning varied with species. Investigating the acute oral toxicity of sodium cyanide in birds, Wiemeyer et al. (1986) observed that the LDso values for the flesh-eating birds were lower than that for the birds that fed on plant material vulture 4.8 mg/kg versus chicken 21 mg/kg. In a study on marine species, Pavicic and Pihlar (1983) found that at 10 ppm concentration of NaCN, invertebrates were more sensitive than Ashes. In animals, the lethal dose of NaCN were in the same range by different toxic routes. A dose of 8 mg NaCN/kg resulted in ataxia, immobilization, and death in coyotes (Sterner 1979) however, the lethal time was longer, at 18 minutes.
