[ ♪INTRO ]
-
It's no secret that birds can be pretty smart.
-
You've probably heard of birds using tools or solving puzzles … but in Australia, they
-
take things to the next level.
-
There, some birds are said to intentionally start fires — making them the only animals
-
besides humans known to do that!
-
Most animals don't like being near fire. The standard instinct around flames is to
-
drop what you're doing and run.
-
But some birds of prey do just the opposite. If they spot a wildfire, they'll actually
-
fly towards it.
-
They've figured out that fire causes little critters to panic and flee, making them easy targets.
-
As long as the birds are careful not to get burned, a fire can mean an easy meal.
-
This incredible behavior is called fire foraging and it's been seen in predatory birds around the world.
-
But in Australian tropical savannas, some birds seem to take this strategy a step further.
-
They're known as firehawks because they're said to fly into active fires, carry away
-
a burning stick in their beak or talons, and then drop it into dry brush to start a totally new fire!
-
There's a lot we don't know about this avian arson. It's never been reliably captured
-
on photo or video, but the stories trace back generations.
-
Around the world, there are human cultures that have lived alongside native wildlife
-
for hundreds or thousands of years. And these cultures can be a valuable source of what's
-
called indigenous ecological knowledge.
-
And a 2017 study set out to collect this local knowledge.
-
Most stories identify three species as the arsonists: black kites, whistling kites, and
-
brown falcons, though there may be other birds that do it, too.
-
And the team found that at least 12 different ethnic Aboriginal groups reported first-hand
-
knowledge of fire-spreading in these birds. They're even in some of their religious ceremonies.
-
One account goes as far as to suggest that early Aboriginal people may have learned the
-
trick of fire-foraging by watching the birds!
-
The study also collected observations from non-Aboriginal people, including modern-day firefighters.
-
As you can imagine, birds that can start fires could be a real pain if you're job is to
-
control blazes, so local firefighters are often on the lookout for the birds.
-
One firefighter reported an instance where he spent an afternoon putting out seven different
-
fires started by kites!
-
And another witnessed a group of birds start a fire that burned so out of control that
-
it damaged a local cattle station.
-
In total, the study found accounts of fire-spreading from West Australia, Queensland, and the Northern
-
Territory — a total area of thousands of square kilometers.
-
So it may not be video footage, but it's pretty comprehensive ethno-ornithological
-
evidence — that is, cultural knowledge of birds.
-
But the behavior still hasn't been scientifically observed and documented, so the researchers
-
aren't done yet.
-
They plan to conduct more interviews, set up field experiments, and equip local rangers
-
with the tools to catch the birds in the act.
-
All that will hopefully reveal how often the birds start fires and how firefighters can
-
best plan around the behavior.
-
And, it may even help researchers figure out how they learned to do it in the first place!
-
Everything we currently know about firehawks comes from people paying attention to nature.
-
Their inquisitiveness allowed them to make remarkable observations of these incredible birds.
-
And, just imagine what you could learn if you indulged your curiosity a little more.
-
