Dear Paul,
do you know the following papers? Maybe you could try to find the
person who made the blood analyses.
Hobson, KA & Clark, 1993, The Auk, Turnover of 13C in cellular and
plasma fractions of blood: implications for nondestructive sampling
in avian dietary studies.
Hobson, K A, Gibbs, H L, Gloutney, M L, 1997, Canadian Journal of
zoology, Preservation of blood and tissue samples for stable-carbon
and stable-nitrogen isotope analysis.
(also on bird blood samples)
Best wishes
Sergine
