Note
Serum chemistry analysis involves the measurements of naturally-occurring enzymes and compounds, which are the result of metabolic and other physiological processes in the blood of birds (Harrison and Harrison 1986). The levels of several chemical compounds in the blood can be usedi n the diagnosis of the health status of individuals (Harrison and Harrison 1986). More emphasis is being placed on the blood as a health-monitoring tool for wild birds (e.g., Dawson andBortolotti 1997, Newman et al. 1997, Olsen et al. 2001, Balbontin and Ferrer 2002).
