Post moult rockhopper penguins (Eudyptes crestatus) had significantly higher plasma alpha-tocopherol (vitamin E), total lipid and total cholesterol concentrations than their pre-moult counterparts. In the magellanic penguins (Spheniscus magellanicus) there were post moult increases in total lipid, cholesterol and alpha-tocopherol concentrations, but only the increase in alpha-tocopherol was significant. Plasma alpha-tocopherol, total lipid and total cholesterol concentrations in post moult gentoo (Pygoscelis papua) chicks were similar to those in non-moulting adult gentoos. Species differences in the levels of these nutrients in plasma may be due to differences in their dietary habits.
