Contributing factors sought as Red Knot population plummets
A new report has revealed a drastic population decline in the Red Knot subspecies Calidris canutus rufa. Numbers at their wintering grounds in southern South America have fallen drastically in recent years; from 51,300 in 2000 to approximately 30,000 in 2004, and still further to just 17,200 in 2006.
The 2007 Red Knot Assessment Report, prepared by the US Fish and Wildlife Service and based on demographic studies covering 1994-2002, reveals that the rufa subspecies could become extinct within ten years, if adult survival remains low.
