Whos that? Marsh Helliborine with her frill...

A Lesser Whitethroat was there greeting in song,
It sung and it sung the whole time long.
The Pyramidal was back, again on its own,
Stood there looking much forlorn,
But who’s that I see peeping the corner?
Its Marsh Helliborine showing off with her frill,
Her friends, all 664, where here, there, and on side of hill,
That’s only a sample of what’s to come, co blimey!!
