I liked the way you flowed in the piece, it's really an art. Nature, most especially animal behaviors gets me stunned sometimes, you mentioned the cuckoo bird, that's one behavior which got me asking the how and why till date, and also I won't forget that of the elephants who morn their dead when they come across one, wonder if that is learned or gened .
It's fun to read about the wonders of life, and just like you told @greenrun, a 100% knowledge of this won't be fun atall. Nice one annie.
WOW, didn't know elephants had that kind of intelligence to know when a fellow dies. learnt something new, at least. Thank you for reading.
