If spring hasn't sprung ...

... it's certainly poised on the starting blocks.

Every time I see them I go back decades to Mam reciting for me.
Not 100% sure of exact words.

"Good morning Mr. Blackbird
with the shining yellow beak,
you'd tell me why it's yellow
if you could only speak.

I'll tell you why it's yellow
'though I can only sing
I dipped it in a crocus
on the first day of spring."
