The hunting bird. 404 notice.

Once upon a bright dew morning,
While the sunlight was adorning
Fish in their shoals – thrice re-forming
headed for the distant shore,

While I swooped, distances mapping,
suddenly there came a tapping,
As of someone gently rapping,
Rapping at my nest-box door.

“Tis a lost friend,” said I swooping,
‘tapping at my nest-box door.

Searching, watching, soaring, looping
Keep hunting, friend – you will score.

Just keep looking: 404
