摘要：

A three year study (1981 to 1983) was conducted to determine possible influences of wetland acidification on the reproduction and growth of the Eastern Kingbird. Egg characteristics and nestling growth were monitored for birds nesting in 26 lakes in the Killarney region near Sudbury, Ontario (pH range 4. 27 to 6. 26). The major percentage of variation in kingbird reproductive factors including clutch initiation, egg weight loss and tarso-metatarsus bone growth was explained by differences between siblings and among nests on a single lake. A smaller percentage of the variance in reproductive parameters was explained by the variation in water chemistry among lakes. The relationship observed between lake acidity and kingbird reproduction is found to be measurable but minor compared to the influence of genetic and inter-nest variables. The study showed no food limitation for the kingbird attributed to lake acidity.
