The numerical abundance of different prey types in regurgitate samples (expressed as the proportion of each prey type out of total prey sampled) of tracked red-footed boobies (RFB n = 15) and brown boobies (BB n = 30) from colonies on the Cayman Islands, during chick-rearing periods between 2016 and 2018. For each species, data are shown for all individuals combined (left sub-figure), and according to sex (right sub-figures; RFB n, female = 6, male = 6; BB n, female = 18, male = 9). Values on bars show the frequency of occurrence (percentage of birds with a prey type present in their regurgitate) of flying fish and ballyhoo
