Red-necked Phalarope: where and when to see them

Red-necked phalaropes are small migratory shorebirds that combine delicate bills with an unusually aquatic lifestyle. They breed around northern freshwater wetlands but spend much of the rest of the year at sea. Breeding females are brighter and somewhat larger than males, reversing the familiar pattern of many birds. Their chestnut neck markings disappear into much paler nonbreeding plumage. In Norway, suitable tundra pools and coastal wetlands provide the main land-based opportunities during summer.

These birds often swim while feeding, sometimes spinning tightly to bring small prey toward the surface. Females court males and may leave them to incubate eggs and rear the young. Males guide mobile chicks around shallow wetlands after hatching. Outside breeding, the species becomes strongly marine and can gather in flocks where currents concentrate food. Migration routes link northern nesting grounds with distant oceanic wintering areas rather than simply following nearby coastlines. The female's bright breeding plumage and aggressive courtship displays are unique among most birds, with males being duller and taking on incubation duties. After the eggs hatch, the male alone cares for the precocial chicks, leading them to feeding areas. During migration and winter, they spend almost their entire lives on the open ocean, rarely coming to shore.

• Females are usually more colourful than males.
• Males perform incubation and most chick care.
• Lobed toes help this shorebird swim efficiently.
• Feeding spins can lift tiny prey toward the surface.

June and July provide the clearest Norwegian breeding-ground window, especially in the north after snowmelt. Some passage birds occur later in summer. Timing varies with latitude and thaw conditions, and accessible wetlands are more useful than general coastal travel dates alone. Prime breeding activity occurs from late June to early July, when eggs are laid and young hatch. By late July and August, many adults and young birds will have started their southward migration. Early arrivals in May are possible, but most are still migrating through.

Breeding habitat includes shallow tundra ponds, marshy lake margins and wet sedge areas, sometimes close to the coast. During migration, sheltered pools and coastal wetlands may be used briefly. Nonbreeding birds mainly occupy offshore waters where fronts and upwellings concentrate plankton. In Norway, breeding sites are typically found in the northern fells and coastal lowlands, especially on small islands or peninsulas. These areas often feature a mosaic of shallow freshwater pools, mossy ground, and sedge tussocks. They prefer open, exposed locations near water bodies with low vegetation.

On breeding grounds, phalaropes take aquatic insects, larvae and other tiny invertebrates from water and vegetation. At sea, they feed largely on small crustaceans and other planktonic prey. Their fine bills pick individual items from the surface with quick, precise movements. Their feeding technique involves rapid pecking at the water surface, often in a characteristic spinning motion to create a vortex. This vortex brings small invertebrates from slightly deeper water up to the surface for capture. Beyond crustaceans, they also consume larval forms of marine worms and small insect larvae found in both freshwater and marine environments.

Identification

Its slim needle-like bill and breeding chestnut neck distinguish it from the broader-billed red phalarope, while nonbreeding birds show a dark eye patch and streaked upperparts. The slender, all-dark bill is a key feature distinguishing it from the stouter, often yellow-based bill of the Red Phalarope. In flight, a prominent white wing bar is visible on both breeding and nonbreeding birds, which aids identification at a distance. Nonbreeding adults and juveniles show distinct white underparts contrasting with grey upperparts, with a dark line extending through the eye.
