Can Wind Farms Slow the Growth of Shorebird Populations?

Vulnerability of northern gannets to offshore wind farms; seasonal and sex-specific collision risk and demographic consequences (2020) Lane et al., Marine Environmental Research, https://doi.org/10.1016/j.marenvres.2020.105196

The Crux

A green on green conflict is what occurs when forms of renewable energy can have a potentially negative effect on the local environment. We see it in hydropower disrupting freshwater fish populations, or in the case of today’s paper, wind farms causing bird deaths. Marine shorebirds are often killed by wind turbines, yet it’s not totally clear to what extent population numbers are impacted by these deaths.

Additionally, whether wind farms are more dangerous to male or female, old or young birds could have a big impact on whether these bird deaths affect population numbers in the future. Today’s authors wanted to investigate this question, using a population of northern gannets off the coast of Scotland.
