Year 2013 and 2014 AICc model results of 7 <i>a priori</i> nest survival models with aquatic prey covariates using Program MARK.

Of 7 a priori nest survival models, 6 different models were supported (ΔAICc <2) in 2013 and 2014 with the null base model having the most weight in both years (wi = 0.25, 0.28). ΔAICc = distance from the top model, and wi = Akaike weight. Variable names are defined in S2 Table.在7个先验巢存活率模型中，2013年与2014年各有6个不同模型获得支持（ΔAICc < 2）；两年均以基准空模型的权重最高，其赤池权重wi分别为0.25与0.28。其中，ΔAICc指与最优模型的赤池信息准则差值，wi即赤池权重。变量名称的定义详见S2表。
