Red-necked Phalarope

The Red-necked Phalarope is a fascinating small wader often found far from shore on the open ocean. These tiny birds display a striking difference in plumage between the breeding and non-breeding seasons. Females are more colorful than males, showing brighter shades during the breeding season.

On their Arctic breeding grounds, Red-necked Phalaropes are blue-gray with a reddish wash on their necks. In winter, they are streaky gray on the back and white below. Despite their modest size, they undertake an incredible migration journey, wintering on tropical oceans.

Their unique feeding behavior is intriguing. The Red-necked Phalarope spins on the water to stir up food, a distinctive trait that sets them apart from other shorebirds. This behavior, combined with their striking seasonal appearances, makes them a captivating subject for bird enthusiasts.

  • They breed in the Arctic and migrate to tropical oceans for winter.
  • They spin on the water to feed, which is unique among shorebirds.

Biology and Species Information

The Red-necked Phalarope, or Phalaropus lobatus, exhibits unique biological traits and behaviors, distinct physical characteristics, and interesting reproductive habits. This section explores these aspects in detail.

Taxonomy and Naming

The Red-necked Phalarope, classified under the genera Phalaropus, belongs to the family Scolopacidae and order Charadriiformes. First described by Linnaeus in 1758, it is also known as the northern phalarope. These birds are small waders, often found in Arctic regions during breeding and on oceans during migration and winter.

Physical Description

Males and females of the species differ in appearance. Females are larger and more colorful, with a distinct red neck, gray back, and white throat. Males are duller and smaller. They have a thin, needle-like bill and lobed toes that help them swim. During winter, their plumage turns gray on the back and white below.

Reproductive Behavior

Red-necked Phalaropes reverse usual sex roles in birds. Females initiate courtship and males handle incubation and care for the young. They nest around Arctic tundra pools. The clutch size is generally 3-4 eggs. Males incubate the eggs and tend to the young once hatched. This role reversal is rare among birds, making their reproductive behavior distinctive.
