The Early Bird Catches the Worm, Defined
The earliest recorded source for 'the early bird catcheth the worm' is John Ray's 1670 proverb collection. What it says and who it leaves out.
John Ray printed “The early bird catcheth the worm” in his A Collection of English Proverbs in 1670. It is the earliest recorded source. The proverb means that whoever acts first gets the advantage. Ray was collecting sayings people already used, so the line is older than the book.
The bird tells this story, and the worm has no say. The worm was up early too. Earthworms of the species Lumbricus terrestris come to the soil surface at night to feed, and a 2025 study in Oecologia on artificial light and Lumbricus terrestris found that light cuts that feeding. At first light some may still be near the surface before they retreat. The robin is catching an animal that got up earlier, which is why the standard reply is that the early worm gets eaten.
Whether early suits a person depends on a body clock that is partly genetic. Birds are loud at dawn possibly in part for acoustic reasons, not only keenness. A rooster’s famous pre-dawn crow is clock-timed and, among several birds, queued by pecking order, which makes it less a sign of keenness than of schedule. Another sleep story with a late source, the one about Bach and a sleepless count, was first written down 61 years after the music.
Camden, mice and worms
Did William Camden write it first? The year is disputed (sources give 1605 or 1636), so Ray’s 1670 entry is the earliest dated one.
What is the second mouse proverb? It is a joke reply: the first mouse springs the trap, and the second gets the cheese. It looks much newer than Ray’s proverb. Dictionaries trace it to the 1990s.
Does the worm have to be awake? No. It only has to be on the surface. Worms surface at night and may still be near the surface at first light, though light makes them retreat.
