Model selection to estimate first-year apparent survival for Prothonotary Warblers, Protonotaria citrea, in southern Illinois, USA, fledging during 2004–2009.

, apparent survival; QAICC, quasi-likelihood Akaike's information criterion corrected for small sample size; wi, Akaike's model weights; K, number of parameters; date, ordinal fledging date; BHCO, reared with cowbird nestmate; noBHCO, absence of cowbird nestmate; cond, nestling body condition; host#, number of warbler nestmates within brood; = , indicates no interaction between terms; ≠, indicates an interaction between terms; year, annual variation; (.), indicates a constant for parameter., 表观存活率（apparent survival）；针对小样本量校正的拟似然赤池信息准则（QAICC, quasi-likelihood Akaike's information criterion corrected for small sample size）；赤池模型权重（wi, Akaike's model weights）；参数数量（K, number of parameters）；序数化出飞日期（date, ordinal fledging date）；存在牛鹂巢伴抚育（BHCO, reared with cowbird nestmate）；无牛鹂巢伴（noBHCO, absence of cowbird nestmate）；雏鸟身体状况（cond, nestling body condition）；窝内莺类巢伴数量（host#, number of warbler nestmates within brood）；等号（=, indicates no interaction between terms）：表示变量间无交互效应；不等号（≠, indicates an interaction between terms）：表示变量间存在交互效应；年度变异（year, annual variation）；常数参数（(.), indicates a constant for parameter）：表示参数为常数。
