The Crotalus durissus collilineatus were most frequently found in pasture and agricultural areas such
as corn cultures, coffee and soy. That happens probably because these places constitute favorable microhabitats, for instance, because of the existence of birds and rodents in that area. The frequency of seasonal distribution was higher during in autumn and lower in the winter, probably due to its reproductive behavior. The probable schedule of main daily activity of this subspecies in the study area varies from 8 to 10 am and from 2 to 4 pm. During the period of 10 am to 2 pm Crotalus durissus collilineatus could be avoiding the high indexes of direct illumination or temperature. Thermal and rainfall factors appear to be correlated positively with the abundance of snakes while the insolation levels seem to correlate negatively, as much as in standard daily and throughout the year.
