Fruit Return Rates for Juvenile Age Classes Compared with Adults.

For each model adults were the reference group. Data were split into food difficulty level subsets: difficult, medium, easy (top to bottom). Model = lmer(total number of bites ~ age class * sex + (1|focal subject ID) + (1|food item ID) + (1|obesrvation number) + offset(log(duration of observation)), family = Poisson). Bite rates are calculated as number of bites ingested divided by the total time it took an individual to forage for a food item.Fruit Return Rates for Juvenile Age Classes Compared with Adults.
