i think this may be correct. Inuits used to call the seasons according to
the main animal they hunted at that time. the same with aboriginals here,
except more in terms of when the animal was at its fattest..such as
kangaroo, eel, et al. so gorge on eel for a couple of weeks, then on to
yellowbelly fish...
