This is the third report from Jean Iron who is surveying shorebirds along 
the south coast of James Bay in northern Ontario for the Ontario Ministry 
of Natural Resources (OMNR). She is part of a crew under the direction of 
research biologists Ken Abraham and Carrie Sadowski. The OMNR is gathering 
information on habitat changes along the coast of James Bay. One change is 
the coastline has moved outward about 150 - 200 metres in places over the 
past 30 years because of isostatic rebound. The land is still rising 
gradually after being lowered by the weight of the continental glacier 
during the last ice age. The land in the James Bay area rises about 1.2 
metres per century. This means a dramatic ongoing advance of the coastline 
because the land is so flat.

Shorebirds observed Saturday (Aug 6) near Shegogau about 20 km north of the 
mouth of the Moose River. Jean surveyed about 1400 metres of coastline 1 km 
south of Friday's location. Saturday was very windy and the temperature 
rose to a warm 28 C. The shorebirds slept for 45 - 60 minutes on grassy 
mounds at high tide before starting to feed again 30 minutes after the tide 
began to fall.
