These positive results provide clear evidence that diversionary feeding is an effective tool to reduce the impact of predation on cappercaillie productivity.
Many land managers across the current cappercaillie range in Scotland are now deploying diversionary feeding for predator management.

To assess if the results of this artificial nest study translated to real cappercaillie broods, we trialled novel non-invasive monitoring via camera traps. We were able to identify if a hen had a brood and count how many chicks she had in her brood.

We found that diversionary feeding is a suitable impact based tool to reduce conflicts between recovering predators (pine marten) and endangered ground nesting birds (cappercaillie) in Scottish Forests.

🚨 New publication 📝
Out today in the royal society proceedings B. We find that diversionary feeding boosts productivity of cappercaille from 0.82 to 1.90. Indicating that this impact based method can effectively reduce the influence of predation.

TAKE HOME: We argue, using several strands of evidence, that diversionary feeding is a credible alternative to lethal control of predators and shows promising signs of reversing the decline of the capercaillie in Scotland.

RESULT: Diversionary feeding increased the number of hens detected with chicks, consistent with our previous work showing a decrease in nest failure. This resulted in productivity (the expected chicks per hen) increasing from 0.82 in unfed sites to 1.9 in fed sites (more than double!). 6/7

HYPOTHESIS: Using a 3-year landscape-scale control-treatment experiment, we predicted that the chicks per hen differed between sites that deployed diversionary feeding and sites that did. 5/7

METHOD: We used #cameratraps on dust baths, natural features used by capercaillie, to detect capercaillie hens and determine whether they had chicks or didn’t have chicks. We used #AI from conservation ai to detect and count hens and broods. 4/7

BACKGROUND: Previously, we found that DF reduced artificial nest depredation, resulting in an 83% increase in nest survival. The big question though was whether this would translate to real birds. 3/7

We quantified the direct impact of diversionary feeding on capercaillie productivity. We show an increase in the proportion of hen with a brood in DF sites (37% -> 85%) and, as a result, a 131% increase in chicks per hen. Read more here: www.researchgate.net/publication/...
