Inter-individual variation in provisioning rate, prey size and number, and links to total prey biomass delivered to nestlings in the Collared Flycatcher (Ficedula albicollis)

Table 3 ANOVA tables reporting the contribution of feeding rate, prey number and size in the total amount of food delivered to the nestlings by parents

	Percentage of larvae among the preys

Data are divided in 3 tertiles, depending on whether a parent was bringing few larvae (1st tertile; < 44.3%), a mixed of larvae and other preys (2nd tertile; 44.3%‒66.7%), or mostly larvae (3rd tertile; > 66.7%). Data are on 164 individuals
