The Claim
In experimental conditions, European starlings with higher levels of omega-6 polyunsaturated fatty acids in their fat stores show increased long-term oxidative damage, despite no immediate change in oxidative costs during or immediately after endurance flight, suggesting a delayed physiological cost associated with PUFA-rich fat composition in migratory birds.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Starlings that have more omega-6 fats in their bodies don’t seem worse off right after long flights, but over time, those fats lead to more cell damage — like a hidden cost that shows up later.

European starlings with higher omega-6 polyunsaturated fatty acid content in their fat stores exhibit increased long-term oxidative damage despite no immediate change in oxidative costs during or right after endurance flight, indicating a delayed physiological cost associated with PUFA-rich fat composition in migratory birds under experimental conditions.
What the research says
1 studyStudy: The energy savings-oxidative cost trade-off for migratory birds during endurance flight
Birds that burned more omega-6 fats during long flights saved energy at first but had more cell damage later, even if they didn’t show problems right away.
