How oil spills affect birds

The video explains how oil exposure affects birds by causing their feathers to mat and separate, which impairs waterproofing and exposes their skin to temperature extremes. This can lead to hyperthermia. Birds instinctively preen to remove the oil, but this can result in ingesting the oil, damaging their internal organs. Preening is crucial for maintaining feather alignment, buoyancy, and insulation.

What are the potential consequences of a bird ingesting oil while preening?

Why is it important for birds to keep their feathers properly aligned?
