What does birdsfoot mean?
Birdsfoot is a common name given to a number of plants whose seed pods or divided leaves were thought to resemble a bird's clawed foot. The best-known example is birdsfoot trefoil, Lotus corniculatus, a low-growing perennial legume native to Europe, Asia, and North Africa that now grows widely across temperate regions. Its cheerful yellow flowers, sometimes tinged with orange, earn it the folk name "eggs and bacon." Beyond its ornamental appeal on roadsides and meadows, birdsfoot trefoil is valued agriculturally as nutritious forage for grazing animals and as a soil-improving plant that fixes nitrogen. The name also attaches to unrelated species, such as certain ferns and violets, so context usually clarifies which plant is meant. In writing, both "birdsfoot" and the more traditional "bird's-foot" spellings appear, with the apostrophized form preferred in formal botanical references.
nounA common name for several plants whose seed pods or leaves resemble a bird's clawed foot, especially birdsfoot trefoil (Lotus corniculatus), a widespread yellow-flowered member of the legume family.
- Any of various plants with claw- or foot-shaped seed pods or foliage, especially birdsfoot trefoil (Lotus corniculatus).
- The plant Lotus corniculatus itself when used as forage for livestock or ground cover.
"The embankment was bright with birdsfoot trefoil in full summer bloom."
"The roadside verge was carpeted with birdsfoot, its yellow blooms fading to orange."
"Farmers value birdsfoot trefoil because it holds its nutritive quality better than many grasses."
The plural is rare in practice; the word almost always refers to a type of plant collectively rather than to countable individuals.
"Several birdsfoots grow along this stretch of the trail."
Its seed pods splay out like a tiny crow's claw — which is exactly how the plant got its name.

Etymology of birdsfoot
The word is straightforwardly descriptive English: it combines "bird" with "foot," dating from the era when folk names were assigned to plants by their resemblance to familiar objects. It arose independently for different species whose claw-shaped seed pods or finely cut foliage suggested a bird's foot, which is why the name covers several botanically unrelated plants. The element "foot" traces back through Old English to the common Germanic root behind related forms such as barefoot and flatfoot.
How birdsfoot is actually used
Usually written with an apostrophe as "bird's-foot" in careful botanical usage, though "birdsfoot" appears commonly in horticultural and agricultural contexts. The word applies to several unrelated plants, so it is normally qualified by the species meant.
