Red-necked Stint

The red-necked stint, or rufous-necked stint, is a small migratory wader, 13–17 cm long with a wingspan of 28–37 cm and a weight of 21–51 g. The breeding adult has an unstreaked orange breast bordered below with dark markings and a white V on its back. The call is a hoarse stit. It is highly gregarious and forms flocks with other small Calidris waders such as sharp-tailed and curlew sandpipers in its non-breeding areas (Wikipedia, general species account).

It is strongly migratory, breeding along the Arctic coast of eastern Eurasia and spending the non-breeding season in Southeast Asia and Australasia, as far south as Tasmania and New Zealand. Eggs are laid in June, three or four, incubated for 20–22 days by both parents; the female leaves soon after they hatch and the male cares for the chicks until they fledge at 16–17 days. SoIB 2023 lists it as a winter migrant of wetland that eats invertebrates, and does not assign a priority category (Wikipedia, general species account; SoIB 2023).
