Abstract:

A study was conducted on black-legged kittiwakes ( Rissa tridactyla) to assess the application of fatty acid (FA) analysis as a method of characterizing seabird diets. I used a free-living, supplementally fed group of kittiwakes to test whether adipose tissue and serum FAs reflected known prey items against a background of natural foraging. I also incorporated hand-reared kittiwake chicks fed separate diets to investigate timelines of FA integration in adipose tissue and serum. For both chapters, I determined how high- and low-lipid prey fed to kittiwakes integrated into their storage tissues. I found that adipose tissue and serum FAs did reflect the known dietary FAs regardless of the lipid content of the prey. I also found that dietary FAs had integrated into chick adipose tissue and serum within a week and 24 hours, respectively, irrespective of the fat content.
