This is Jean Iron's third report by satellite phone on 1 August 2010 for
he period 23 July to 1 August 2010 from Longridge Point on southern
ames Bay. Jean is a volunteer surveying Red Knots and other shorebirds
nder the direction of Mark Peck of the Royal Ontario Museum, Toronto.
On 31 July four more people arrived at camp and one there departed. Don
utherland of the Ontario Ministry of Natural Resources (OMNR), Mike
cMurtry (OMNR), Doug McRae (ROM volunteer) and Ray Ford (writer)
rrived and Christian Friis (Canadian Wildlife Service) left. Mark Peck,
isa Pollock (Trent University/OMNR) and Jean Iron are staying until the
urvey ends about 15 August. Seven people are in camp.
SHOREBIRD MIGRATION CHRONOLOGY: Most (not all) southbound shorebirds
igrate in three waves: females first, males second, juveniles last.
emales depart soon after the young hatch leaving the males to raise the
oung. The males depart about 2-3 weeks later when the juveniles have
rown. Then juveniles migrate after the males.
bout 7000 shorebirds are currently in the Longridge Point area. There
re no Peregrine Falcons to disrupt their feeding. Best day for high
ounts was 29 July after a storm. For most species only the high count
ay is given below in checklist order.

Ruddy Turnstone: 415 adults on 29 July.
RED KNOT: The high count of 1143 molting adults was on 29 July. The
xtensive tidal flats of southern James Bay are an important stopover
rea for knots. 120 marked individuals have been observed with several
irds seen over a period of 12-14 days indicating a long stay. Mark Peck
nd shorebird researcher Lisa Pollock are sampling the foods eaten by
he knots. They noted that the knots are plump and in excellent
ondition. These knots will likely fly nonstop to South America.
igrating knots that fail to gain adequate weight suffer reduced
