Which is a reliable reference that provides relative sensitivity to oil of all bird species in the northern latitudes?
Taej,
See the Handbook of Ecotoxicology, 2nd edition (Lewis Publishers) Hoffman, Rattner, Burton and Cairns editors. Oil of course is a complex mixture. Toxicity depends on season of exposure route of exposure, life stage exposed, and the degree to which the oil mixture contains various PAH compounds and nitrogen. Species seems less important a factor. External exposure results in hypothermia related problems. Internal exposure results in various forms of toxicity depending on the mixture. Seabirds appear to be particularly vulnerable. There are also indirect habitat type effects as well as direct toxic effects. Egg oiling with even a few drops of oil is embryotoxic.

Steven, Many thanks for this reference, I have checked it out and it provides useful background information. I understand that the sensitivity can vary depending on exposure and particular situation, with seabirds being more vulnerable. I am trying to find a list of species that may be considered at a higher risk from a published reference. Best regards, Taej
