Abstract
Common flicker (Colaptes auratus) and mountain bluebird (Sialia currucoides) eggs were examined 1 year after DDT application and showed a marked difference. Residue levels in mountain bluebird eggs were approximately 10 times higher than in common flicker eggs (5.29 to 0.58 ppm wet weight). These differences can be explained by disparate dietary habits. The mean level in American kestrel (Falco sparverius) eggs collected in the spray area at the same time was 6.42 ppm wet weight.Keywords
