- Xenus cinereus
Identification
Length 22–25 cm (8¾-9¾ in), wingspan 57–59 cm, weight 50–126 g
- Very long, slightly upcurved bill, black with a brownish-yellow base
- Upperparts and breast buffy grey to silvery grey
- Dark carpal patch
- Mainly white underparts
- Legs 'dayglo' orange-yellow, shorter than most Tringa 'shanks'.
- Breeding adult: broad black scapular stripes and black streaks on coverts; white supercilium
- Winter adult: paler and greyer; scapular line inconspicuous
- Juvenile: duller, sandy brown; scapular line inconspicuous
- In flight shows white trailing edge on secondaries and inner primaries (as in Common Redshank but less broad)
Distribution
Breeds in far eastern Europe (locally in Finland, and from Belarus and Ukraine eastward) and across northern Asia. Winters on tropical coasts in east Africa, south Asia and Australia.
Rare, but regular visitor to the British Isles, mostly on passage but one or two wintering records.
Taxonomy
This is a monotypic species[1].
Formerly often included in the genus Tringa, but genetic evidence shows it to be more closely related to Phalaropes Phalaropus[2].
Habitat
Breeds beside muddy or gravelly riversides and lakeshores; typically nesting among greyed driftwood on riverbanks. On migration on freshwater marshes. In winter, coastal mudflats, estuaries and mangroves.
Behaviour
Diet
Food is small aquatic invertebrates; it chases insects and other mobile prey, and sometimes runs to the water's edge to wash its catch.
Breeding
They lay 3-4 eggs in a lined ground scrape.
