Herd of deer (Odocoileus hemionus) in San Pedro Mártir National Park, Baja California, Mexico. Herd of more than 17 individuals that are grazing in the central valley of the reserve in the early hours of the morning. San Pedro Mártir is one of the regions of Mexico where I have been able to observe the largest herds of adult specimens.  They are concentrated in this region because it is one of the few areas with grasslands in a desert environment (Photograph by Sergio Ticul Álvarez Castañeda).
