A recent study conducted in Nepal's southern plains reveals that human activities are detrimental to bird diversity. Researchers analyzed 238 bird species in both human-altered and natural habitats. They discovered that human actions, such as logging and hunting, filter out sensitive species, leading to a decline in both the number and variety of birds. In contrast, diverse habitats, which include forests, fields, and wetlands, support a greater variety of bird species. The study emphasizes the importance of conserving natural habitats to enhance bird populations and maintain ecological balance. It suggests that managing human activities and restoring habitats can help mitigate biodiversity loss.
