A wildlife biologist studies animals and their habitats to understand their behaviors, populations, and ecosystems. They often conduct field research, collect data, and analyze the effects of environmental changes on wildlife. This work helps in conservation efforts and informs policies to protect endangered species. Wildlife biologists may work for government agencies, non-profit organizations, or research institutions. They often collaborate with other scientists and conservationists to develop strategies for habitat preservation and species recovery. Their research can involve various species, from birds and mammals to reptiles and amphibians, contributing to the overall health of ecosystems.
