Wind Turbines and Birds – A Difficult Relationship

The increasing number of bird deaths linked to wind turbines is a serious issue that should not be ignored. The US government estimates around 573,000 birds are killed each year in America due mostly because they fly too near large spinning blades-including eagles and hawk species! In this piece, we will be looking at why bird deaths are so high and what steps are being taken to mitigate the problem.

The Problem

The problem is that wind turbines are often built in areas where there are large populations of birds. This is because these areas have strong winds, which are necessary for the turbines to operate.

As the blades of the turbine spin, they create a ‘wind shadow’ behind them which can extend up to 0.6 miles (1 km) from the turbine. Unfortunately, birds that fly into this shadow can be sucked into the turbine and killed because of the high wind speeds. In addition to the wind shadow, turbines also produce low-frequency noise that can disturb birds. This noise can impact the birds’ migratory patterns and reproductive success.

The problem of birds being killed by wind turbines is likely to increase in the future as more and more turbines are built. To reduce the impact on birds, it is important to carefully site turbines in areas where there are not high concentrations of birds. In addition, the blades of the turbine should be designed to minimize the wind shadow they create.

It is estimated that each turbine can kill up to two birds per day, which adds up to a lot of dead birds over the course of a year!

There are several reasons why birds might fly into the wind shadow of a turbine. For example, they may not be able to see the turbine until it is too late, or they may be chasing after prey and not paying attention to their surroundings.

Some birds are also attracted to the turbines because they mistake them for trees or other tall structures. This is especially true for migratory birds who are looking for places to rest during their journey.

The Solution

There are a few different ways that wind farms can reduce the number of bird deaths. One is to build the turbines in areas where there are fewer birds.

Another solution is to use ‘bird deterrents’ such as flashing lights or loud noises to scare birds away from the turbines. Some companies are even experimenting with using lasers to create a virtual barrier around the turbines!

The best solution, however, is to simply stop building wind turbines in areas where there are large populations of birds. This may seem like a drastic measure, but it is the only way to guarantee that no more birds will be killed by these turbines.

Is It Just Birds?

No, its definitely not just birds. Bats and wind turbines have an interesting relationship. Bats are attracted to wind turbines because they use them for roosting and hunting. The blades of wind turbines create an updraft that bats can use to take flight, and the open space around wind turbines provides a good hunting ground for insects. However, this relationship can also be deadly for bats. When they fly into the blades of wind turbines, they can be killed or seriously injured. As a result, wind turbine operators have been working to find ways to reduce the risk to bats, such as turning off the turbines at night during peak bat activity periods.

Wind turbines can also pose a threat to local wildlife, particularly bats. A study by the U.S. Fish and Wildlife Service found that wind turbines kill an estimated 573,000 bats each year in the United States alone. Bats are especially vulnerable to wind turbines because they rely on echolocation to navigate. The high-pitched noise created by the turbine blades can interfere with their echolocation system, causing them to collide with the blades or fly into the turbine tower. In addition, wind turbines can disrupt bat mating and hibernation habits, further jeopardizing their populations. While wind turbines offer many potential benefits, it is important to consider the negative impact they can have on local wildlife before constructing them.

The problem of birds being killed by wind turbines is likely to increase in the future as more and more turbines are built. To reduce the impact on birds, it is important to carefully site turbines in areas where there are no high concentrations of birds. In addition, the blades of the turbine should be designed to minimize the wind shadow they create.

Until this happens, however, the deaths of birds caused by wind turbines will continue to be a serious problem.
