Empirical evidence that diversionary feeding increases productivity in ground-nesting birds
Jack Anthony Bamber e outros, 2025 · Proceedings of the Royal Society B: Biological Sciences
Deploying deer carrion to divert generalist predators significantly reduced the log-odds of a capercaillie hen having no brood by 2.268.

Contexto
What changed: Seasonal provision of deer carrion across 1 km2 grid cells during capercaillie egg laying and early chick rearing. Comparison: Unfed control grid cells in a randomized crossover design over three years. Limits: Evaluated in a single Scottish pine forest landscape; monitoring relied on camera traps at dust bath sites.
