The
name Phalarope refers to any of three species of slender-necked
shorebirds in the genus Phalaropus of the bird family
Scolopacidae. They are 6–10 in (15–25 cm)
in length, with lobed toes and a straight, slender bill.
Predominately grey and white in winter, their plumage
develops reddish markings in summer. They are especially
notable for two things: their unusual nesting behavior,
and their unique feeding technique. The typical avian
sex roles are reversed in the three Phalarope species.
Females are larger and more brightly colored than males.
The females pursue males, compete for nesting territory,
and will aggressively defend their nests and chosen mates.
Once the females lay their eggs, they begin their southward
migration, leaving the males to incubate the eggs and
care for the young. When feeding, a phalarope will often
swim in a small, rapid circle, forming a small whirlpool.
This behavior is thought to aid feeding by raising food
from the bottom of shallow water. |
