NWGS = Northwestern Garter Snake
RSGS = Red-spotted Garter Snake (Common GS)
No attempt was made to monitor temperature conditions. Snakes were in a narrow 2 foot long aquaria with screen lid with one end place on top of a large cage housing gravid female boas and where on end of the Ringneck aquaria was near the 60 watt light bulb used as a heat source in the boa cage.
Substrate was 1 inch deep coarse Douglas fir sawdust on one half of the cage lengthwise and 1 inch of composted soil. The substrate was overlaid with 1/2 inch of native moss and on top of the moss was small, slightly curved pieces of bark as hides.
At the end of the aquaria nearest the light bulb was kept moist and dry at the other end. When I noticed that the snakes were seeking the cooler end, I moved the aquaria away from being directly over the light bulb. When I found the snake occupying the heated end, I knew I had the correct conditions as far as warmth is concerned. Real fancy setup!
My set up with the 5 Sharp-tailed Snake females was similar except they were in a larger aquaria with an overhead lamp at one end. All five Contia produce their eggs as well.
In the mid 1990's I maintained a few gravid Ringneck females to obtain eggs in order to perform feeding trials with the Rubber Boa. I don't think I kept track of female wts. etc. but recall the first year I did not get any eggs and had difficulty with having females take prey. The next year in which had success getting eggs, I threw every kind of prey I could think of. I know this species take our Long-toed Salamander with gusto but the salamander is not available on the surface during the day once it becomes warm and dryer. I recall putting in juvenile garter snakes, worms, slugs, perhaps insect larvae, large termites, small lizards, and Pacific Tree Frog tadpoles and newly metamorphed juvenile frogs. I did not keep track of which female ate what prey but did notice a few female eating the pollywogs and small frogs.
