The term halcyon days usually refers to the past times in one’s life when there a calm, happiness or successful period.
The term derives from the Latin word Alcyone who in mythology was daughter of Aeolus and wife of Ceyx. Her husband died during his shipwreck. The grief stricken Alcyone threw herself into the sea. After that both were transformed into halcyon birds identified as Kingfishers. For example the biological name of the white throated kingfisher is Halcyon smyrnensis.
When the birds made their floating nest on the sea, Aeolus restrained his winds and their was a period of calm of 14 days at the winter solstice, so that the eggs hatch into chicks and become birds.
The word halcyon comes from “Hals” meaning “sea or salty” and “kyon” meaning “to conceive” meaning to conceive in sea.
White throated kingfisher is a very beautiful bird. It is quite common in our area. Although going by its name, it is mainly a fish eater but it has modified its eating habits. It can catch insects, small rodents and lizards. That is why it can be found sitting on trees in the fields away from the water bodies.
