ooperative effort with the Ontario Ministry of Natural Resources
OMNR), Canadian Wildlife Service (CWS) and Trent University.
he past several days have been mainly sunny with daytime high
emperatures below average with cool nights. High tides have been weak
o shorebirds were less concentrated for counting. Usually only high
ount day numbers for each species are listed below in checklist order.

rom Delaware Bay (USA) observed on 20-21 July. After breeding in the
anadian Arctic, rufa Red Knots migrate to stopover areas such as
outhern James Bay, where they fatten for the long flight to South
merica. Another rufa population winters in Florida. Florida knots are
are in James Bay. Longridge was chosen as the ROM's survey site because
igh numbers were recorded there in the past. A one-day estimate of 5000
t Longridge was made in the late 1970s before the decline.

paringly in the prairie-like marshes of James Bay.

andhill Crane. Yellow Rail numbers are much lower than last summer
ossibly linked to drier marshes this year. Some Yellow Rails may have
hort-stopped to breed in the areas such as southern Manitoba, which is
ery wet this summer with many reports of singing Yellow Rails.
hort-eared Owl, pair with two young. Gray Jay, pair with a blackish
uvenile. Swainson's Thrush singing. Orange-crowned Warbler singing. Le

ggs on 19 July. Small numbers of White-winged Crossbills and Common

Mammals: A dead Beluga, 3 metres in length, washed up on shore. Crew
opes the carcass will attract scavengers such as Red Fox, Gray Wolf and
ynx whose tracks have been seen during surveys. Two Black Bears seen on

Map link below of southern James Bay. Yellow pointer shows location of
ongridge Point. Ontario borders the west coast of James Bay and Quebec
orders the east coast. Provincial boundaries extend to the low water
ark on James Bay. Offshore islands extending to the low water mark are
art of Nunavut Territory. The waters and seabed of James Bay are
nternal parts of Canada under exclusive federal jurisdiction and not
art of Ontario, Quebec or Nunavut.
Jean will call again in 4-6 days and I'll post her third report.
