Field Identification

c. 15·5–19 cm; 37–44 g (1); wingspan 42–48 cm (2). Above pale sandy grey ; forehead brownish; lores  black; rump and base of tail white, with black subterminal band; primaries black, contrasting with pale coverts, secondaries white with black trailing edge; below  pale rufous-buff, shading to white on lower belly and undertail; underwing  black with white bar across secondaries and inner primaries; bill  black with small amount of red at base; legs dusky to black. Adult non-breeding duller, loses black lores. Differs from G. cinerea by plain head and darker underwing. Juvenile scaled and spotted buff-grey and brownish above; spotted and streaked pale brown below, with all-black bill.

Systematics History

Sometimes placed in Galachrysia with G. cinerea and G. nuchalis. Closely related to G. cinerea. Monotypic.

Subspecies

Monotypic.

Distribution

E Afghanistan and Pakistan, through India, Sri Lanka and Bangladesh to S China (S Yunnan), and thence S & SE through Myanmar to Thailand, Laos and Cambodia. Scarce non-breeding visitor in Arabian Gulf and Oman.

Habitat

Large rivers and streams with exposed sandbars, rocky islands and shingle banks, up to c. 1800 m in Himalayas, but just 450 m in SE Asia (3); also coastal marshes, estuaries; also large inland lakes when not breeding.

Movement

Locally migratory, depending on water levels of rivers, but present in many breeding areas only Apr–Aug, moving to lower elevations in winter. Mainly or exclusively summer breeding visitor to Bhutan (4), Pakistan (but up to 350 birds recorded in Jan) and NE Afghanistan (5); disappears from R Indus in midwinter, though over 500 birds seen together on Indus in Mar. Elsewhere, probably mostly short-range movements reported in response to changing water levels (6). Vagrant or uncommon winter visitor W to Yemen, Arabian Gulf (Bahrain, Iran and United Arab Emirates) and Oman, early Nov–late Feb, with occasional records in Mar, Jul and Sept (7, 8, 9); also S to Malay Peninsula (as far S as Singapore) in mid Nov to late Jan (10, 11).

Diet and Foraging

Beetles, bugs, termites, flies and other insects, including dipterans, coleopterans and hemipterans (2). Crepuscular; forages in large flocks on the wing, either high in air or low over water or ground, in zigagging flight like a swallow; may also catch insects by running on ground like plover. When feeding may recall pipistrelle bat (Pipistrellus) with which it often flies in twilight.

Sounds and Vocal Behavior

Gives a raspy, strongly downslurred, short “chirrrt”, given at a rate of 1–2 notes/1–2 seconds, as well as a high, rolling “prrip” or “tiririt” in flight, and a short “tuck-tuck-tuck” given by incubating bird (said to recall house gecko Hemidactylus sp.). Advertising call is Little Tern-like (Sternula albifrons), a rising “temik-temik-temik” (2).

Breeding

Lays Feb–Apr in India and Sri Lanka; from Mar in Pakistan; Apr–May in Laos (with copulation observed Dec and fledged young Jul) (12, 13); early Apr in NE Cambodia (14); eggs as late as third week of Jun in N Vietnam, when other pairs already had fledged young (15); just-hatched chicks in Mar in Bhutan (4); young in Jun in E Afghanistan. Nests colonially , often dozens of nests together, sometimes with River Terns (Sterna aurantia), Black-bellied Terns (S. acuticauda) or Indian Skimmers (Rynchops albicollis), with individual nests usually 5–10 m apart (2). Nest  a shallow scrape, or no nest at all; on sandbank in river , even up to water’s edge. Clutch 2–3 eggs  (2–4), sandy buff to sandy grey with small reddish-brown, lavender and greyish markings, mean size 25·9 mm × 20·5 mm (3); incubation  17–18 days, by both sexes; during hot hours of day, attentive periods 25–35 minutes long; incoming parent often wets belly plumage before return to nest, to cool eggs. Chick  finely mottled greyish white, pale buff and dusky above  ; narrow black line behind eye; below  white. Chick fed by regurgitation; when threatened, mock-incubation and broken-wing distraction displays frequently performed by adults; fledging period not recorded. Unseasonal rains or snow melt may cause flooding of early clutches, but birds lay again soon after, even as late as Jun.

Not globally threatened (Least Concern). Total population estimated to be in range 10,000–100,000 birds. Species seems able to survive adequately in large numbers throughout range and is considered to be reasonably tolerant of relatively high levels of human disturbance (12, 13, 6). Flock of 2000 recorded at Chitwan, Nepal, Jan 1983, and c. 1270 observed on upper R Mekong, Laos, in winter (6); flocks of a few hundred birds often seen in S Nepal. Has been listed for Kashmir, but status there uncertain (5), and known breeding sites in N India apparently just three (Chambal National Wildlife Sanctuary, West Yamuna Canal, Haryana, and Pong Dam Wildlife Sanctuary, Himachal Pradesh) (16). Only recently confirmed to breed in Vietnam, from observations made near Hanoi (15).
