The red-necked stint forages on the shore and occasionally in shallow water (6), picking rapidly at the ground as it darts between feeding spots. An omnivorous species, it feeds on insects, small invertebrates, molluscs, crustaceans and gastropods, as well as seeds and plants (3).
Relatively little study has been undertaken on the red-necked stint’s breeding behaviour. However, it is known that the male’s breeding display involves fluttering and gliding over its breeding territory while uttering a repeated call. Following its aerial display, the male drops to the ground with its wings held high in a sharp ‘V’ above its back (6).
The red-necked stint is a ground-nesting species, typically building its nests on mossy hummocks (6). Built between May and July (4), the nest is shallow and lined with willow leaves. The female red-necked stint generally lays four olive or buff-coloured eggs that are blotched with brown. Incubation is believed to be carried out by both sexes, and is thought to last approximately three weeks. The female often abandons the newly-hatched chicks, which are then looked after solely by the male red-necked stint (6).
As it is a sociable species, the red-necked stint is often found in mixed-species flocks within its non-breeding habitat. It generally occurs with other waders, such as curlew sandpipers (Calidris ferruginea) and sharp-tailed sandpipers (Calidris acuminata) (7).
