A recent observation of mine, When my son and I took CY the corn snake out for photos, The first time he did this meant nothing to me, he lifted his tail and SECRETED (not pooped, or musked) onto the rocks, ten minutes later in the pines, he SECRETED again.

The third time sold me. about 500 feet from the second spot, his tail lifted up, and this wet stuff got smeared onto the log he was climbing.

As a semi-educated guess, I would assume that to be Territorial marking.

Tomorrow, I will conduct an experiment, just for fun.

The mother Eastern (Diana - Goddess of fertility) gave birth in her enclosure, I will salvage some of the aspen, salvage some aspen from the red sided garters, and use some new aspen, place each under a separate hide, and note where the neonates chose to spend the most time.
