Emma Neave-Webb, from the Orkney Marine Mammal Research Initiative (OMMRI), confirmed there have been some concerns about its injuries.
On a post on the OMMRI’s social media, she wrote: “In situations like this there is often little that can practically be done – nature generally takes its course and there are obviously difficulties in safely getting close to an animal of this size let alone treating it.
“What this does mean is that keeping your distance and allowing the animal to rest undisturbed is even more important than usual. Stress will not help its recovery.
“The best thing anyone can do for this walrus right now is leave it in peace.”
A walrus appeared in North Ronaldsay, Orkney’s northernmost island, in 2013.
Another was spotted at same island before heading a bit further south and resting on the island of Sanday in 2018.
