Capped Langur at the Khadim Nagar National Park in Sylhet, Bangladesh on October 16, 2023. Capped Langurs are considered vulnerable to extinction as their populations are declining rapidly and most are not connected to each other, which leads to unhealthy inbreeding. Despite this, they can fairly easily be seen in many national parks in the eastern region of Bangladesh. (Photo by Zabed Hasnain Chowdhury/NurPhoto/Rex Features/Shutterstock)
