Heliolisk also has Dry Skin, which provides it an immunity to Water-type moves and therefore allows it to threaten a multitude of Water-type Pokemon in UU. It also has a nice immunity to Ghost-type moves, meaning it can switch into Choice-locked Chandelure and nab a free Volt Switch. While Heliolisk has two immunities and a colorful movepool, it is weak to common attacking types in UU such as Ground and Fighting. This is also exacerbated by the fact that it has pitiful 62 / 52 physical bulk, meaning even resisted physical hits are going to take a chunk of Heliolisk's HP.
In fact, wind turbines are way down in the pecking order. Besides habitat degradation and destruction, the top human-built environmental threat to our feathered friends are buildings. As many as 970 million birds crash into them annually, according to a June 2013 study in the Wilson Journal of Ornithology.
While the review by scientists does not provide all the answers, it suggests wind turbines are tall enough to attract insects migrating at night, which typically fly at heights of over 60m. Bats and birds are then killed by turbine blades as they feed on this insect bonanza. In particular, they measured how a turbine's colour alters how many insects gather around it. Most turbines are painted pure white or light grey, in a bid to make them as visually unobtrusive as possible.
