Rare Alaskan migrant
A rare wading bird that breeds in Alaska and usually migrates to Chile and
Argentina has crossed over to the wrong side of the Pacific Ocean and made a
wetland reserve on the edge of the Avon-Heathcote Estuary its new home. The bird, a Lesser Yellowlegs or Tringa flavipes, was found recently by park
rangers in Charlesworth Reserve, a wetland next to Humphreys Drive which was
created by the Council especially for wading birds. The yellowlegs is brownish-grey, with pale undersides and bright orange-yellow
longish legs – hence its common name. This one was found tagging along with
a small flock of Pied Stilts that have a breeding colony beside the Estuary. “The bird is only about half the size of a Pied Stilt, which makes its journey even
more remarkable,” says park ranger Andrew Crossland. “To reach Christchurch
it has either flown across the Pacific islands from Alaska or has crossed over to
North Asia from Alaska and probably flown southwards through Japan, the
Philippines, New Guinea and Northern Australia.” |
