1) Teyteyka, the hot season which is a period for collective celebrations and the time for building -> from July to November
2) Amian, the cold season “when everyone stays put” -> from November to March
3) Rayyon, fishing season for migratory fish -> from March to July

This information was quite useful for me. I am writer as well as anthropologist for environment. From this particular standpoint, I would like to know any local Haiku (Japanese poem composed by 5-7-5 syllabuses) with the stress of rich seasonal changes. So, local people may have written some similar poems emphasizing the beauty of every season. Thank you, Hori Takeaki (hori_takeaki@hotmail.com)
