How does the cuckoo know?

"The Cuckoo comes in April, sings his song in May, in June he changes his tune, in July away he must fly."

Bang on cue, heard my 1st Cuckoo today near Achvarasdal...but how did he know that it was the Ist of May?

Hi LIZZ

Either it's TIMING or the Cuckoo wrote the saying, incidentally, I also heard a Cuckoo at Achvarasdal today.

Lol....I just had a terrible thought, may be he has a clock mechanism!

Heard my first cuckoo yesterday too Lizz and first swallows arrived today - summer is on its way!
