No reproduction in blue-winged teal (Anas discors) and northern shovelers (Anas dypeata) reproduction inhibited by 60% in coots (Fulicia americana) and red-winged blackbirds (Agelaius phoeniceus) disruption of food cycles in marsh was probable cause (NRCC 1975)... 

Acute oral toxicity of mirex to warm-blooded organisms was low, except for rats and mice, which died 60 to 90 days after treatment with 6 to 10 mg mirex/kg body weight (Table 21.1). Birds were comparatively resistant. The red-winged blackbird (Agelaius phoeniceus) was unaffected at 100 mg mirex/kg body weight, although it was considered the most sensitive of 68 species of birds tested with 998 chemicals for acute oral toxicity, repellency, and hazard potential (Schafer et al. 1983).
