Birds tend to fly into wind turbines by mistake<\/strong>. There are a few reasons for this.<\/p>\n

One major reason why birds cannot easily spot wind turbines is that the long, rotating blades create a misleading view of empty space as they spin rapidly.<\/p>\n

Birds often collide with turbines for years without being able to avoid doing so<\/strong>.<\/p>\n

In recent years, however, researchers noticed that some types of wind turbines seemed to alter the flight path of birds approaching them.<\/p>\n

They would slow down or turn back before reaching<\/strong> the area where the turbine blades rotated.<\/p>\n

At first, it was unclear why these particular turbines were any different than all the others.<\/p>\n

A hidden problem in how birds see turbine blades<\/h2>\n

There\u2019s more behind it. The first reason is that the rotating blades of wind turbines<\/strong> appear unlike anything else birds normally try to avoid.<\/p>\n

Not only do the blades move fast, but also the way that light reflects off of them means that there will sometimes be periods when the blades seem almost invisible.<\/p>\n

This creates a serious risk of collision.<\/strong><\/p>\n

A second reason turbines pose hazards to birds is that they are much more likely to approach standard white blades than other designs.<\/p>\n

Scientists believed that they needed to make the blades more visible<\/strong>. Previous studies had shown that birds would continue to fly towards the new colored blades as though they saw no difference.<\/p>\n

It seemed as though changing the color of the blades was not enough.<\/p>\n

Subtle changes in bird flight behavior<\/h2>\n

The next stage in research was to find out if there were other ways than just determining whether<\/strong> or not animals could see the turbines, to measure animal responses to different visual cues.<\/p>\n

Birds in controlled laboratory environments were provided with a variety of designs for spinning turbine blades<\/a> and compared against one another.<\/p>\n

But when the patterns changed, their behavior changed<\/strong> \u2014 they slowed down.<\/p>\n

They stopped and assessed the situation.<\/p>\n

Sometimes they completely reversed course and went in<\/strong> another direction.<\/p>\n

The greatest reactions occurred when using unusual patterns that had high contrast such as black, red, and yellow.<\/p>\n

Researchers then focused on understanding why certain patterns<\/strong> created such a strong response.<\/p>\n

Bird deaths from turbines can reach into the hundreds of thousands each year, leading researchers to study this behavior in \u201cBiologically inspired warning patterns deter a passerine, Parus major, from digital turbine blades\u201d published in Behavioral Ecology<\/a>.<\/p>\n

The thinking behind \u201csnake\u201d wind turbine designs<\/h2>\n

When researchers placed similar warning-style patterns onto turbine blades, they found that birds reacted differently. <\/strong>The change was noticeable almost immediately in controlled observations.<\/p>\n

Rather than continuing to travel in a straight line, these animals will either come to an immediate halt or will turn abruptly off course.<\/p>\n

This method is easy and direct. It doesn’t require creating new turbines, nor does<\/a> it depend on birds learning over time how to avoid them in different environments or conditions.<\/p>\n

The basis of this approach appears to rely upon signals that many species of birds may already naturally understand.<\/p>\n

How patterned blades influence bird movement<\/h3>\n

Studies demonstrate that birds visit patterned blades significantly<\/a> fewer times.<\/p>\n

When they do, they hesitate more frequently, which can make a crucial difference in helping them.<\/p>\n

That hesitation provides additional time for birds to alter<\/strong> course and remain distant from turbines.<\/p>\n

Across large wind farms, even small changes could make a real difference, helping to reduce bird fatalities over time in many different regions.<\/p>\n

If a single pattern can cause a bird to alter its course in mid-air, what other risks exist simply because animals<\/a> perceive the world differently from us?<\/p>\n","protected":false},"excerpt":{"rendered":"
