What happens when a bird is oiled?

What is the survival rate of birds affected by oil spills?

The survival rate will differ with each oil spill because of all the factors that effect it. Some of those factors are the toxicity of the oil, how rapidly the birds are collected and stabilized, what condition the bird was in before it was oiled, and the species involved.

What happens if a bird eats an oiled bird?

What are the effects of pollution on birds?

This pollution induced anemia results in immunodeficiency or immune-suppression which leaves these birds susceptible and vulnerable to infectious diseases.
