Red Knot and Hudsonian Godwit in Bahia Lomas,
Tierra del Fuego Island, Chile
The
Red Knot Calidris canutus rufa, carries out an extensive
migration from the breeding territory towards the coasts of Fuego
Patagonia, where about 50% of the wintering population flying to South
America spend the winter. On the other hand Hudsonian Godwit
Limosa haemastica, is a shorebird which breeds in the northern
extreme of North America (Alaska and the east of Canada) and also
migrates towards South America, in a different route thought, to spend
the boreal winter.
Between 2001and 2003 the New Jersey Fish and Wildlife Service,
under the of Dr. Larry Nyles together with independent Chilean
researchers and other institutions, carried out studies about ecology of
both Red Knots and Hudsonian Godwits wintering in the shores of Bahia
Lomas in the north of Isla Grande of Tierra del Fuego, Chile. These
studies??? area coordinated by R. Matus and Olivia Blank.
Censuses have been done to the whole bay during all these years.
The
first campaign was mostly cordination in the field to figure out where
the birds where and after 10 days with no successful catching, we had a
very good idea about how to work in the future.
During the second campaign (2002) veterinarian thesis student from
University of Chile, Ana Roa, carried out a study consisting in blood
sampling from the birds with the intention to determine whether these
birds carry or not diseases known for other birds like Newcastle
disease or Salmonella.
In 2003 Phd in Ecology Carmen Espoz from Santo Tomas
University in Santiago, has developed a study on bahia Lomas inter
tidal in order to characterize invertebrates using this mudflats and in
this way to study the diet of shorebirds using the bay as a foraging
area.
Between 2001 and 2003 studies on the ecology of the Red
Knots and Hudsonian Godwits wintering in Bahia Lomas (Tierra del Fuego
Island) has been carried out by the New Jersey Fish and Wildlife Service
together with local researchers. To see details on the different surveys
