     California’s migratory deer population is suffering from what wildlife experts call “hair loss” syndrome. However, the real problem appears to be from the infestation of non-native lice with symptoms that range from a scruffy looking hair coat to near complete baldness. Researchers are not sure how the lice arrived, but they do suspect it is having serious impacts to the state’s deer population. Wildlife biologists speculate that the deer spend so much time grooming that they become easy targets of prey for coyotes, mountain lions and other carnivores. This impacts the survival rate of fawns, which is less than half of what it should be.
