2003
Journal of Experimental Biology
Preserved Fulltext
To fuel their exceptionally high mass-specific energy demands, nectar-feeding birds often experience water fluxes closer to those experienced by amphibians and freshwater fish than to those of endothermic vertebrates (Beuchat et al., 1990) . Extremely high water flux rates have been measured in many species of nectarivorous and frugivorous birds (Rooke et al.
