Drone Disruptions: When Birds Become Drone Difficulties

Have you ever lost a drone because of a bird? If not, you're not alone. Bird attacks on drone operations are not uncommon, and can range from minor disruptions to full crashes. In this article, we explore the incidents of bird versus drone interactions and how understanding these interactions can prevent future mishaps.

Experiences with Bird Interference

As an experienced drone pilot, I have encountered several instances of bird interference, but not a single drone loss. However, I have faced crashes and near-misses due to birds, and so have my flying partners. Here are a few notable incidents:

Photogrammetry Mission Harassed by Oyster Caters

During a mission for a high-value client, a drone was repeatedly harassed by an oyster catcher. The incident lasted nearly 35 minutes out of an hour-long flight, with the bird 'buzzing' the drone. It was speculated that the bird had a nest nearby, explaining its aggressive behavior. Birds are generally more likely to harass a drone if they perceive it as a threat to their nest or territory.

Close Encounters with Eagles and Other Predators

When encountering birds of prey, such as eagles, the response is usually to ignore them. Our experience with eagles over nesting sites suggests that birds perceive repeated intrusions as a threat. Despite the repeated attacks, our drones were not often brought down due to the agility and resilience of our aircraft. In one instance, after nearly crashing twice, a property owner witnessed an eagle diving towards the trees, which solved the mystery of the drone's unexpected behavior. In another case, an RC plane suffered damage but was not brought down due to the eagle's near-miss.

Understanding the Impact of Bird Interference

The impact of bird interference on drone operations can be severe, leading to crashes or near-misses. Here are a few key points to consider:

Unexpected Disruptions During FPV Flying

FPV flying can be particularly challenging when a bird decides to attack. For instance, I was practicing drone racing on private property when an eagle dive-bombed my drone during a flight. Despite the drone's undamaged appearance and its ability to fly perfectly post-repair, unexpected bird attacks can be difficult to diagnose initially. Understanding these attacks can significantly impact flight planning and equipment maintenance.

Flight Clearance and Path Planning

Flight clearance and path planning are crucial to avoid bird attacks. Flying near known nesting sites or areas with a history of bird activity should be avoided. Additionally, using familiar tracks and natural features can help in delineating safe flying areas. In one instance, after witnessing an eagle in the area, I changed my course and never faced unexplained crashes again.

Precautions and Solutions

To prevent bird attacks and ensure safer drone flying, pilots can take several precautions:

Monitor and Avoid High-Risk Areas

It's essential to stay informed about high-risk areas and avoid flying near known nesting sites or areas with a history of bird attacks. This includes researching the flight area before any operation begins.

Invest in Sturdier Drones

While lighter drones may provide better agility, investing in sturdier aircraft can help protect against minor bird attacks. Ensuring that drones have robust materials can reduce the incidence of damage.

Gather Local Knowledge

Local knowledge and informants can provide valuable insights into bird behavior and nesting sites. Pilots should engage with local property owners and conservation groups to gather this information.

Conclusion

While bird attacks can be a significant challenge to drone operations, understanding and preparing for such incidents can significantly reduce the risk of crashes. By avoiding high-risk areas, choosing appropriate drones, and gathering local knowledge, pilots can enjoy smoother and safer flights.
