Israeli Study Explores Porcupine Grief Behavior
Translated & summarized from Ynet by baba
An Israeli study using trail cameras in Ramat Hanadiv Nature Park captured a golden jackal preying on a porcupine cub, with the jackal later observed with quills in its nose and chest. Following the jackal's departure, an adult porcupine retrieved the cub's remains, a behavior researchers suggest could indicate a response to the death of a relative due to the species' strong family bonds. This rare observation offers potential insights into porcupine emotional responses and highlights the challenges and importance of wildlife research.

- An Israeli study documented a golden jackal preying on a porcupine cub, with quills found in the jackal's nose and chest.
- An adult porcupine was filmed retrieving the cub's remains after the jackal left the scene.
- Researchers hypothesize the porcupine's action may be a response to the death of a relative.
- The study suggests Indian crested porcupines may have strong family bonds leading to emotional responses.
- Trail cameras provided rare footage of this potentially grief-related behavior in wild rodents.
A rare observation captured by trail cameras in Israel's Ramat Hanadiv Nature Park may offer insights into the emotional lives of porcupines, specifically their response to loss. The study, conducted by Dr. Amir Arnon of Ramat Hanadiv and Dr. Torsten Wronski from Liverpool's University of John Moore, documented a golden jackal preying on a porcupine cub on two separate occasions. Notably, in one instance, the jackal was observed with porcupine quills embedded in its nose and chest, providing the first scientific evidence of active predation on porcupines by golden jackals.
Researchers noted that the jackal, despite the availability of human-related food sources like garbage, chose to hunt the dangerous porcupine. The jackal was later seen without the quills, suggesting it managed to dislodge them, possibly due to the cub's smaller, less developed quills. This behavior might indicate the jackal specialized in hunting young porcupines.
Most intriguingly, eight minutes after the jackal left with the cub, an adult porcupine, likely a male, approached the scene. Trail camera footage showed this porcupine collecting the remains of the cub in its mouth, with a quill protruding from the carcass, and carrying it away from the area.
Two hypotheses were proposed for this unusual behavior. The first, less likely according to the researchers, was cannibalism or osteophagy (bone-eating) for mineral supplementation, as porcupines have never been observed feeding on carcasses in previous studies at Ramat Hanadiv. The second, more plausible hypothesis suggests a response to the death of a relative. Given that Indian crested porcupines form lifelong monogamous pairs and share parental care for nearly a year, researchers believe strong family bonds could lead to an emotional reaction to a family member's death, similar to observed behaviors in elephants.
Dr. Arnon highlighted the rarity of such observations in wild rodents, attributing the lack of documentation to research challenges rather than the absence of the phenomenon. He emphasized the value of trail cameras in overcoming these obstacles, allowing for unobtrusive, round-the-clock observation. These findings underscore how little is known about animal behavior when unobserved and stress the importance of environmental conservation.
