TABLE 5 Model averaged parameter estimates, their standard errors and unconditional 95 % confidence intervals from models explaining habitat use of pairs and broods. Estimates are based on all models in the candidate model set using Akaike weights as weighting factors. CI = confidence interval, TYPE = pond (compared to lake), SHORE = wetland shoreline (km), FOOD = invertebrate food index, FIELD = field percentage within 1 000 m buffer zone around the wetland.
