Wood Sandpiper
Least ConcernTringa glareola
Visual Identification
Wood Sandpiper
Appearance
The Wood Sandpiper is a small wader with a slender build. It has a brown-speckled upperpart, white underparts, and a prominent white eyebrow. The legs are yellowish-green, and the dark yellow bill is dark and straight, tipped with grey.
During the breeding season, adults develop darker, more heavily marked plumage. Females develop their breeding plumage slightly earlier in the season, which can be used as a key way to determine between the sexes.
Both sexes are alike in plumage, although females are slightly larger. Juveniles resemble adults but have buff-tinged upperparts with more prominent spotting.

Distribution
Wood Sandpipers breed in subarctic and boreal regions across Europe and Asia. They prefer open wetlands, bogs, and marshy areas near woodlands. During migration, they can be found in a variety of freshwater habitats.
Up to 30 pairs of Wood Sandpipers breed in the UK each year, but these are limited to a small area of marshy land in the western Highlands of Scotland.
In winter, they migrate to Africa, southern Asia, and Australia. In the UK, they are passage migrants, seen mainly during spring and autumn migrations, with occasional winter sightings. Eastern and southern England report the most sightings during this time.

Diet
Wood Sandpipers primarily feed on insects and their larvae, including mosquitoes, flies, spiders, and beetles. They also consume small crustaceans, molluscs, and occasionally small fish.
These birds forage by picking prey from the water's surface or probing in shallow mud.
Behaviour
Wood Sandpipers are often seen bobbing their heads and tail while foraging. They typically feed alone or in small, loose groups, probing the mud with their bills.
During migration, they form larger flocks and can be quite vocal, especially when alarmed.
Vocalisation
The Wood Sandpiper has a distinctive call, often described as a clear, ringing 'chiff-if-if' or 'giff-giff-giff'. Their call tends to carry far across long distances, both in the day and night.
During the breeding season, males produce a melodious song in flight, a series of repeated 'tlui-tlui-tlui' notes that can last for several minutes.
Nesting & Breeding
Wood Sandpipers form monogamous pairs during the breeding season, typically from May to July. Males perform aerial displays to attract mates, making circular flights while calling.
Nests are usually built on the ground, often near water and concealed in vegetation. The female lays 3-4 pale olive-green eggs with brown spots. Both parents take turns incubating the eggs.
Incubation lasts about 22-23 days, with both parents taking part. Chicks are precocial and can leave the nest shortly after hatching. They fledge after 26-28 days, becoming independent soon after. The male typically does most of the post-hatching parental care.
Lifespan
The Wood Sandpiper typically lives for 7 to 9 years, with a maximum recorded lifespan of 11.7 years.
Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.
Conservation and Status
Global Conservation Status
While the Wood Sandpiper is currently listed as Least Concern, it faces threats from habitat loss and degradation, particularly in its breeding and wintering grounds.
Conservation efforts focus on protecting wetland habitats and managing water levels in key areas.
Birdwatching Tips
- Look for Wood Sandpipers near freshwater habitats, especially during migration.
- Listen for their distinctive 'chiff-if-if' call when in flight.
- Observe their characteristic tail-bobbing behaviour when foraging.
- In the UK, check coastal wetlands and inland reservoirs during autumn migration.
