  • Was at a zoo recently and a random duck flew and landed on top of a harpy eagle enclosure. The eagle flew up from underneath and, landing upside down on the roof of the cage, it reached with one of its claws and grabbed the duck through the chain link fencing. It then proceeded to furiously yank at the duck and *ripped it to shreds* pulling it through the few inches of space. I wont go into detail, but it was absolutely horrifying in many many ways..

He looks over and and an eagle has its claws in the seagulls back and would fly 10 feet up, slam it into the ground and repeat till death. It then flew away and ate it on top of Cavendish farms.

Invasive species is such a huge issue globally, and purposefully releasing 2 apex predators on a population of creatures explicitly because they are vulnerable to attack is such a brutal thing to do. But damn does it make for dramatic science. Movie needs to happen.

  • I wonder if the Harpy calls weren't only used to identify primates without a response but to actually wear down their awareness overtime by conditioning them to expect calls before seeing the eagle. We might see more of those mix-ups and mindgames if we observed them in areas where primates lived alongside eagles for more than a year.

But there are some baboons who normally, yell and scream and make a ruckus when they see a predator coming.. but near this water hole where a pride of lions go, the baboons have learned to stay quiet and let the lions take an ungulate hanging around, so they didn't hunt the monkeys. 🤷‍♂️ same same but different?

Clearly exagerations, wild tales, but it shows the reverence, respect and even fear the Harpy commands on people. Also, the state police here where I'm from has _Harpia_ as a callsign their helicopters.

  • We saw a Harpy chick on its nest in eastern Venezuela several years ago, one that had been filmed by the BBC. The chick was as large as an adult, but mostly white and still impressive, 120 feet up in a ceiba tree. Caretakers lived nearby in a cabin and showed us the nest. As we were leaving, we heard a whistled cry, and one of the guys said "adulto!" We hurried back, and there was the female bringing some monkey part to the chick. She looked stared down at us with the fiercest glare I've ever seen from a bird. Gave me the willies!

    • This level of intellect can be seen in tigers as well. Tigers are even known to imitate prey noises. My theory is this. If you are a heavy predator lacking in speed and a group but is solely reliant on living, agile prey for diet, you adapt by being more intelligent. In the documentary about harpy eagles, a strange thing the researchers noticed was that the harpy eagle chick they were studying, almost a year old wasn't shying away when these guys came to its vicinity. It was watching them intently, studying them. Knowledge and Being accustomed to the patterns matters when you are a heavy meat eater.

  • That's really interesting that the Harpys almost instantly began using calls to conserve energy when hunting, even though (assumedly) that wouldn't be their normal strategy in areas where primates lived with them for any length of time. Why could observational studies not be done elsewhere though, to get a glimpse at more developed behaviours? Was it just lack of funding or was their a special benefit of the island beyond a lack of predators?

  • Just got back from Alaska the other day. The Bald Eagle was a common sight. My river fishing guide showed me a video of a large eagle harvesting an adult king salmon from the river a few weeks earlier. Seeing an eagle take an adult salmon from the river (easily 10+ lbs) definitely gave me new found wisdom in the power of an adult eagle. Harpy eagles are 10-20%+ heavier than the Bald Eagle. I can't imagine its strength.

  • This video was of such quality, I replayed it at 1.0x after my initial 1.5x troll. Love the details surrounding Harpy visual acuity & staggered fovea. Another obscure tactic or strategy is that as Harpy young are raised, the quarry inside the nest kill zone are intentionally preserved & avoided. As the young matures into adulthood, the prey within the nest kill zone becomes the practice quarry. Pretty clever, eh? *_TRUST !!_*

    • actually it's not quite the golden ratio. the video said that the eagle's highest accuity vision occurs at about 45 degrees to the head axis, which means that the pitch of the spiral path it follows is about 45 degrees. The golden spiral's pitch is approximately 17 degrees. Therefore, the eagle's path is more closely tied to some other metallic ratio, which generates a different member of the logarithmic spiral family.

  • I think it would have been useful to continue that research, mostly because, well, that's still very limited experience and doesn't show the limits of a harpy eagle's hunting intelligence. And, you know, since we are inspired by other species so much, perhaps there is something about the strategy of wild carnivores that we could use even for less violent purposes, or from the strategy of wild prey... Since we're so willing to shut animals in cages and milk them for venom, or inject things into them, why not make full use of these animals... besides, the insight gained, these animals would be living in a far more natural environment with far more freedom... to me there are worse experiments people can be or are conducting than this.
