Which risk increases when avian plumage develops significant oil fouling?

💡 Explanation

When plumage develops significant oil fouling, disruption of feather barbule interlocking occurs because the oil impairs feather structure adherence, leading to decreased insulation capacity. Therefore reduced thermoregulation results, rather than enhanced maneuverability or buoyancy, which relies on clean feathers air entrapment respectively.
