The park's deputy director told BBC Newsday that they had learned to imitate their carers, who have looked after them since they were found.
"Wow that is an awesome office you've got there", said one commenter of Mr Shamavu's workplace. Stay safe and thank you for the awesome work you do'.
In total, 179 rangers have died in the line of duty. While gorillas can be risky to humans and have be known to kill, a strong bond has formed between the critically endangered primates and the Virgunga park rangers.
In order to become a ranger at the park, prospective staff must complete an extensive six month training regimen.
Senkwekwe is a UNESCO World Heritage site and now houses 22 gorillas, according to its website.
Another ranger, Hakizimana Sinamenye Chadrack, died in March after sustaining serious injuries from a hippo, the park said on its website.
And just days later, another ranger was struck by lightning.
"I was very surprised to see it... so it's very amusing". In this case, it was a hippo mother, who had a calf with her, ' the park said in a release.
The photo's come after one man died on March 29, after he was attacked by a hippo. The park quickly addressed those concerns.
However Shamavu, a former worker for the Congolese Institute for the Conservation of Nature, saw nothing unusual in the primates' pose.
The safari park was launched back in 1925 and is among the first protected areas in Africa. In altitude, it ranges from 680 m in the Semliki River valley to 5,109 m in the Rwenzori Mountain.
The park was established nearly 100 years ago primarily to protect mountain gorillas.
A team of 600 rangers work across the park to keep wildlife safe from poachers and human incursion, in a region which has been impacted by war and conflict.
