Table 2. Results of MANOVA on time-activity budgets of downy young (>12-d-old) Common Loon chicks. Predictive variables were compiled separately for each lake. CPC1-3 are the first three principal components of lake chemistry. Time-activity budgets quantify the proportion of time spent in various behavioral states. Pillai's Trace criterion for significance testing in MANOVA was used. Maximum probability (Type I) error was set at 0.05.
