Drones Spy On Birds in Flight - Scientific American
Studying birds for a living might sound like a cool job. But it's not
without its logistical challenges, for us landbound animals. "I can
remember precisely a location where I had a northern gannet, so a really
large bird, breeding on the top of the cliff."
David Grémillet, a seabird ecologist at the French National Center for Scientific Research.
"And from the bottom of the cliff I couldn't see what was happening in
that nest. I couldn't even see whether the bird was home or not."
Grémillet says technology offers a simple solution: "A drone carefully
flown at high altitude over the colony would have been really helpful."
That's right—a drone. Grémillet says scientists and citizens alike are
increasingly using drones to approach birds—either for fun or legitimate
research. But they’re taking flight without knowing how the aerial
robots might affect their avian study subjects.

Estimating how many birds are roosting at these sites a real
challenge. The only option so far has been to count them as they fly in
before dark, jotting down their numbers as quickly as possible. But they
are not done arriving and moving around until after dark, and counting multiple flocks as they come from all directions is not easy!
To get accurate counts, what you’d ideally want to do is wait until
after dark, when they’ve all arrived and settled down, then count them
from overhead. A serious challenge.
This spring we tested a new technology that we think has the
potential to provide much better bird counts on a regular basis and will
help us track populations in ways we haven’t been able to before:
Unmanned Aerial Vehicles (UAVs or drones).
UAVs are the new black in tech, kind of like Web 2.0. We’re fielding
at least a call or email each week about a start-up or university lab
that is looking at novel ways to use drones.
And there’s been some great conservation applications by WWF and conservationdrones.org.
At its core a UAV is any type of aircraft (fixed wing or multi-rotor)
that can be flown autonomously by providing way points with mission
planning software.

Unmanned aerial vehicles (UAVs), known colloquially as drones, don’t
offer just a safer way for scientists to observe their subjects; they’re
often less costly, more efficient, and more precise than traditional
approaches. As Junda can attest, biologists are still navigating the
challenges and complexities of mixing wildlife and drones, working to
improve maneuverability, autonomy, and endurance—and hitting regulatory
hurdles. Learning curve aside, the technology holds incredible
potential. “Drones are going to change the way that data is collected,”
says Leanne Hanson, a U.S. Geological Survey biologist who has used them
to count migrating Sandhill Cranes.
