Variation in carbon and nitrogen stable isotope ratios in flight feathers of a moulting White-bellied Sunbird Cinnyris talatala. Ostrich, vol. 82(3), pp 163-1660030-6525http://www.ajol.info/index.php/ostrich/article/view/71280http://www.tandfonline.com/doi/abs/10.2989/00306525.2011.618248http://hdl.handle.net/10204/6040Copyright: 2011 NISC. This is an ABSTRACT ONLY.The authors measured d13C and d15N isotope signatures in flight feathers of a White-bellied Sunbird to assess the value of using stable isotopes of feathers in avian dietary studies. Significant variation in d13C and d15N isotope values of flight feathers (range = 3.1‰ and 2.7‰, respectively) indicated that the source of carbon (i.e. C3 or CAM) and trophic level position shifted significantly during the flight feather moult period. Temporal dietary changes in an individual sunbird highlight the implications for interpreting avian diets using stable isotopes. However, by analysing feathers, dietary input may be interpreted at different levels if the moult process is well understood.enWhite-bellied sunbirdsAvian dietary studiesFlight feathersAvian dietsCinnyris talatalaCarbonNitrogenIsotope analysesSunbirdVariation in carbon and nitrogen stable isotope ratios in flight feathers of a moulting White-bellied Sunbird Cinnyris talatalaArticleSymes, C., & Woodborne, S.
