How do you tell a lesser yellowlegs from a greater? With the bill, the call, and — if you're patient — the behavior
If This Animal Could Talk...

What is that elegant, yellow-legged shorebird that looks exactly like a greater yellowlegs except smaller, thinner, softer, and less interested in screaming at you? That's a lesser yellowlegs, and she's the reason birders develop trust issues.
The lesser yellowlegs (Tringa flavipes) is the other yellowlegs — the one that doesn't blow your cover every time you approach a mudflat, the one that forages methodically instead of sprinting after fish like she's auditioning for an action movie, and the one that calls with a soft, polite tu-tu instead of the greater yellowlegs' three-note air-raid siren. She's also considerably more numerous than her larger counterpart, which means you're statistically more likely to be looking at a lesser when you find a lone yellowlegs at a North Louisiana impoundment. But good luck being sure about that without hearing the call, because in plumage the two species are essentially identical.
A Few More Facts
How they hunt and forage: What do lesser yellowlegs eat? The same things as the greater, but with less drama. Lesser yellowlegs feed on aquatic and terrestrial invertebrates, including flies, beetles, insect larvae, worms, snails, small CRAWFISH, and occasionally small fish and seeds. Their foraging style is more methodical and less frenetic than the greater yellowlegs' — they walk steadily through shallow water, picking prey from the surface or probing lightly into soft substrate, without the greater's tendency to sprint, lunge, and side-sweep through the shallows. The lesser yellowlegs pecks and picks rather than plows and chases. She's the type-A student working through a problem set while the greater yellowlegs flips the table and improvises.
Live birth or eggs? no
When young are born: Adults arrive first, often by early July — only weeks after they left the breeding grounds — and juveniles follow from August through October.

Accessibility
Accessibility
Lesser yellowlegs are highly accessible shorebirds thanks to their abundance during migration, their use of diverse wetland habitats, and their tolerance of moderate human presence from vehicles and observation areas. They're one of the most frequently encountered shorebirds during fall migration, which means opportunities to observe them are plentiful across the region.
For visitors with mobility considerations, lesser yellowlegs can be observed from vehicle-accessible roads, auto tour routes at NWRs, levee roads at WMAs, and paved park trails adjacent to ponds and wetlands. They forage in open, flat habitats that are visible from any elevated or roadside vantage point. Their abundance during fall migration means you don't need to find a specific site — any shallow water in our 26 parishes has the potential to hold lesser yellowlegs from July through November.
For visitors with vision considerations, the lesser yellowlegs' call is softer and less carrying than the greater's, but it's still audible at moderate distances and diagnostic once learned. Mixed flocks of yellowlegs are often detectable at distance because the greater yellowlegs' loud alarm calls signal the presence of lesser yellowlegs foraging in the same flock. A spotting scope is recommended for working through mixed flocks to practice the greater/lesser comparison — it's the single most rewarding investment a North Louisiana shorebirder can make.

Frequently Asked Questions
Does Lesser Yellowlegs live in North Louisiana?
Yes. She's also considerably more numerous than her larger counterpart, which means you're statistically more likely to be looking at a lesser when you find a lone yellowlegs at a North Louisiana impoundment. The lesser yellowlegs is a common migrant across our 26 parishes, passing through from mid-March through May in spring and from early July through November in fall.
She breeds in the boreal forests and muskegs of Canada and Alaska, winters from the southern United States through Central America, the Caribbean, and into South America, and uses North Louisiana as a critical refueling station in both directions.
