Stable isotopes reveal opportunistic foraging in a spatiotemporally heterogeneous environment: Bird assemblages in mangrove forests
Fig 6
δ13C and δ15N values of sources (mean ± sd) and mangrove bird consumers at Cocoa Creek and Healy Creek for each isotope-based foraging group.
Sources that were unable to be distinguished by mixing models were combined. Inset plots show the probable relative contribution of sources (95% credible interval ranges), as estimated by mixing models, to the diet of each foraging group.
