Large Birds Demonstrate Technical Innovation in 90% of Tasks
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Large birds like emus and rheas show capability for technical innovation by solving physical tasks to access food, suggesting this ability evolved earlier in birds than previously believed.
📈 One key stat: Emus moved the hole in the most efficient direction toward food in 90% of test cases, demonstrating clear problem-solving abilities in these supposedly ‘dumb’ birds.
💬 One key quote: “The more we study palaeognath birds, the more we can understand the broader picture of bird cognition. And because palaeognaths birds are the closest living relatives to dinosaurs, research might shed light on how dinosaurs behaved.“
1️⃣ The big picture: Scientists have discovered that large flightless birds like emus and rheas can solve complex physical problems to access food, overturning previous assumptions about their intelligence. In a groundbreaking study at a local zoo, researchers tested three palaeognath species using a rotating wheel puzzle that required aligning holes to receive food rewards. Emus successfully created a technique to line up holes with food chambers, while a male rhea developed two different methods to solve the task. This research challenges the longtime perception of these birds as unintelligent and suggests that technical innovation in birds may have evolved much earlier than previously thought.
2️⃣ Why is this good news: Understanding that large birds possess problem-solving abilities helps reshape our perspective on animal intelligence and evolution. These findings open new avenues for studying cognitive abilities across different bird species, moving beyond the usual focus on crows and parrots. The research provides valuable insights into the evolution of intelligence in birds and may help us better understand dinosaur behavior, since these birds are their closest living relatives. The discovery of technical innovation in supposedly ‘dumb’ birds encourages scientists to look more broadly at cognitive abilities across different species.
3️⃣ What’s next: Researchers plan to conduct more cognitive studies focusing specifically on palaeognath birds. The rotary task needs to be tested with other bird species to enable fair comparisons of problem-solving approaches. Scientists aim to build a broader understanding of bird cognition by expanding research beyond traditionally studied species like crows and parrots.
