Drones and avian activity (birds)
The fact that many birds are considered migratory is well known to the average person. Indeed, you've probably noticed that in autumn, birds leave for warmer climes, then return to Canada in spring, when temperatures are more comfortable, to breed. Although there's always a risk of seeing or colliding with a bird, there are three periods when the risk is highest: during spring and autumn migratory activities, and when the birds have laid their eggs and are protecting their offspring.
During migration (spring and autumn)
During these periods, migratory birds fly in huge flocks of the same species to leaveor return to Canada. They present an enormous danger to any aircraft flying in the airspace with them. On the other hand, aircraft also present a considerable danger to these animals. Since drone pilots generally operate at altitudes of400' AGL or less, they need to be particularly cautious and alert to avian activity.
The Aeronautical Information Manual, section RAC 1.10.2, states the following:
"Low-level flying over migratory birds can cause considerable harm to these birds. Geese in particular have a great fear of aircraft, and their movements can be seriously disrupted as a result. More over, many bird species in Canada are indecline. We must do all we can to protect them.
In the last section of this article (Aviation Resources), since prevention is better than cure, we've provided a number of information tools to help you learn more about this subject.
When birds protect their offspring
Like mostliving creatures, parent birds are even more protective of their offspring when it's new. It's not uncommon to see birds literally attacking to protect their offspring. Before undertaking any flight, be sure to inspect the surroundings.If in doubt, simply move to another location to protect the peace and quiet of young bird families.
Conclusion
Finally, despite all the knowledge and tools we have at our disposal, the best thing wecan do as pilots is to be aware of our surroundings at all times when flying in the air. Especially when we're flying at low altitude. To do this, use the visual scanning technique and, if possible, bring along a visual observer,because four eyes are better than two! If, despite all the caution you've exercised, you encounter birds during your flight, simply move away from the min the safest way possible, trying to avoid their trajectory. If necessary, land!
