James Bay 3
August 2005 - Report #1 |
I just talked to Jean who's a member of
a crew of eight surveying the birds and vegetation along the south
coast of James Bay. The project is headed up by research scientist
Ken Abraham of the Ministry of Natural Resources (MNR). They're
comparing vegetation changes with studies done 30 years ago. Jean
has the lucky job of surveying the shorebirds. The crew is staying
at the MNR staff house in Moosonee and flying by helicopter to
different points every day along the coast. As I get daily reports,
I'll post to Ontbirds.
Today along 1 km of coast 8 km west of
Netitishi Point on James Bay:
Black-bellied Plover, 1 adult on tidal
flats
Semipalmated Plover, 225 adults on tidal
flats
Greater Yellowlegs, 30 adults and
juveniles
Lesser Yellowlegs 15 adults and
juveniles
Hudsonian Godwit, 50 molting adults on
tidal flats, some in almost full alternate plumage and others almost
in basic plumage
Ruddy Turnstone, 1 adult
Semipalmated Sandpiper, 200 adults and
10 juveniles
Least Sandpiper, 5 adults and 30
juveniles at edge of vegetation in pools and along muddy creeks
White-rumped Sandpiper, 300 molting
adults on tidal flats - 800 yesterday at another location. This is
the commonest shorebird.
Pectoral Sandpiper, 50 adults in same
habitat as the Leasts
They also had lots of Yellow Rails and
Nelson's Sharp-tailed Sparrows.
Happy birding,

James Bay 5
August 2005 - Report #2 |
This is the second report from Jean Iron
(she just phoned me in Toronto from Moosonee) who's surveying
shorebirds (as part of a larger study) along the southwest coast of
James Bay for the Ontario Ministry of Natural Resources. James Bay
is the southern extension of Hudson Bay. It cuts deep into central
Canada providing a route for tundra and boreal breeding shorebirds.
The west coast of James Bay is in the province of Ontario and the
east coast is in the province of Quebec, but the islands of James
Bay belong to Nunavut Territory. The Ontario coast of James Bay is
very flat. At low tide the feeding areas for shorebirds are immense.
James Bay is one of the most important subarctic staging areas for
shorebirds in North America. The numbers reported here are tiny
considering the extent of the coastline.
Shorebirds seen Friday at Shegogau which
is 20 km north of the mouth of the Moose River on James Bay in
Ontario - GPS 0533358.
Black-bellied Plover, 1 adult
American Golden-Plover, 1 adult
Semipalmated Plover, 58 adults, 1
juvenile
Greater Yellowlegs, 97 adults and
juveniles
Lesser Yellowlegs 75 adults and
juveniles
Whimbrel, 3 adults
Hudsonian Godwit, 158 molting adults
Red Knot, 28 molting adults
Sanderling, 70 molting adults
Semipalmated Sandpiper, 2349, less than
5% juveniles
Least Sandpiper, 146 mostly juveniles
White-rumped Sandpiper, 1418 molting
adults
Pectoral Sandpiper, 78 adults
Other birds of interest today were 16
Sandhill Cranes, 2 adult Arctic Terns, 8 Yellow Rails (still
actively calling), 35 Nelson's Sharp-tailed
Sparrows, 2 Le Conte's Sparrows, and 1
juvenile Northern Shrike.

James Bay 6
August 2005 - Report #3 |
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.
Semipalmated Plover, 17 mostly adults
Greater Yellowlegs, 34 mostly juveniles
Lesser Yellowlegs, 65 mostly juveniles
Hudsonian Godwit, 4 molting adults
Red Knot, 10 molting adults
Sanderling, 8 molting adults
Semipalmated Sandpiper, 2263, about 8%
juveniles, numbers of juveniles increasing
Least Sandpiper, 12 juveniles
White-rumped Sandpiper, 1732 molting
adults
Pectoral Sandpiper, 4 worn adults
Note # 1. Molting shorebirds are in body
molt; none in wing molt.
Note # 2. Other birds of interest were
12 Sandhill Cranes, 3 Yellow Rails and 2 Nelson's Sharp-tailed
Sparrows.

James Bay 7 August
2005 - Report #4 |
This is the fourth report from Jean
Iron (she phoned late last night) who is surveying shorebirds along
the south coast of James Bay in northern Ontario for the Ontario
Ministry of Natural Resources. Hudson Bay and James Bay are an
extension of the Atlantic Ocean reaching deep into central Canada.
The adjacent Hudson Bay Lowland is one of the largest wetlands in
the world supporting large breeding populations of Hudsonian
Godwits, Greater Yellowlegs, Lesser Yellowlegs, Solitary Sandpipers
and Common Snipe (Ross et al. 2003).
Shorebirds seen Sunday (Aug 7) about 20
km north of the mouth of the Moose River near Shegogau on southern
James Bay.
Black-bellied Plover, 6 adults.
Semipalmated Plover, 39 adults, 10
juveniles.
Greater Yellowlegs, 63, more than half
juveniles.
Lesser Yellowlegs 168, more than half
juveniles.
Whimbrel, 22, probably adults.
Hudsonian Godwit, 25 molting adults.
Marbled Godwit, 3, the coastal
prairie-like marshes of James Bay support a isolated breeding
population of perhaps a "few thousand" Marbled Godwits (Ross et al.
2003).
Red Knot, 203 molting adults, but still
mainly in alternate plumage, James Bay is important to the large
staging flocks of knots.
Ruddy Turnstone, 3 adults.
Sanderling, 4 worn and molting adults.
Semipalmated Sandpiper, 4852, increasing
numbers of juveniles; banded birds from near here in the past were
seen at Presqu'ile Provincial Park on Lake Ontario.
Least Sandpiper, 182, mostly juveniles.
White-rumped Sandpiper, 2648 molting
adults, most of these adult birds move southeast across Quebec so
very few are seen in southern Ontario.
Pectoral Sandpiper, 78 adults.
Note # 1. Other birds of interest today
were 7 Yellow Rails including a sighting of 2 dark young.
Note # 2. The Ministry of Natural
Resources crew has seen Black Bears using coastal habitats. Jean saw
big foot prints in the mud on the tidal flats. Polar Bears are not
usually seen in southern James Bay, but one was sighted there this
spring. However, there are currently about 50 Polar Bears only 200
km farther north on Akimiski Island (Nunavut). This is the most
southerly population of Polar Bears in the world. The Ministry is
concerned about the physical condition of these Polar Bears because
of the very early spring and warm summer which caused early ice out
on Hudson Bay and James Bay forcing the bears to the coast or onto
islands. These bears will lose a month or more time to hunt seals
and put on weight. The hot weather this summer is stressing them
too. They'll be in poor shape this fall if freeze up comes late. The
Hudson Bay and James Bay populations of Polar Bears are at risk
because of climate change.

James Bay 8 August
2005 - Report #5 |
This is the fifth 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.
Below is a list of the shorebirds observed on Monday (Aug 8) about
20 km north of the mouth of the Moose River near Shegogau on
southern James Bay. The survey was done at low tide so the birds
were spread out. At low tide the flats extend 1 - 2 km or more. Over
the next two weeks of August there will be a rapid shift in numbers
from adults to juveniles in many (not all) species of shorebirds.
This turnover applies to southern Ontario around the lower Great
Lakes as well.
Black-bellied Plover, 3 adults in
different stages of body molt.
Semipalmated Plover, 22, 75% juveniles.
Greater Yellowlegs, 49, mostly
juveniles.
Lesser Yellowlegs 56, mostly juveniles.
Whimbrel, 3, age unknown.
Hudsonian Godwit, 15 molting adults.
Thousands of this species stage and fatten along the west coast of
James Bay before flying non-stop to South America. Most adults leave
during the last 10 days of August. Juveniles begin to gather along
the coast in early September and depart from mid-September to early
October.
Marbled Godwit, 2, age unknown.
Semipalmated Sandpiper, 1412, 50%
juveniles.
Least Sandpiper, 301, all juveniles.
White-rumped Sandpiper, 790 molting
adults.
Pectoral Sandpiper, 350 adults, first
juveniles should arrive this week or next.
Dunlin, 1 adult still mainly in very
worn alternate plumage. See # 1 below.
Note # 1. Molt Strategies: Almost all
adult Dunlins of the subspecies hudsonia (only subspecies breeding
in Canada) will remain farther north
to undergo a complete definitive
prebasic molt before migrating south after mid-September. Juvenile
Dunlins also remain in the north to undergo a partial first prebasic
body molt of body feathers before migrating south. Purple Sandpipers
follow this molt strategy too. However, most adult shorebirds
undergo varying degrees of body molt before migration (very slight
in a few to none in many species) and during migration at staging
areas where there is considerable body molt in many species. Most
adult shorebirds delay molting flight feathers until reaching the
wintering grounds. Most juvenile shorebirds depart the nesting areas
in full juvenal plumage. Depending on the species, there are varying
amounts of body molt at rest stops and staging areas as in adults.
Note # 2. Reports from Hudson Bay and
from farther north indicate that most shorebirds had a good breeding
season in 2005.
Note # 3. I had a question about Red
Knots. How are numbers doing this year versus past years? It is
difficult to say based on Jean's one survey location. The coastline
extends for hundreds of kilometres. The Hudson Bay and James Bay
coasts of Ontario are of "hemispheric significance to staging
flocks" of southbound Red Knots (Ross et al. 2003), probably being
the fall equivalent to Delaware Bay. The Canadian Wildlife Service
(CWS) does aerial surveys along the coast of James Bay, but I have
not heard of recent numbers of knots. The CWS also does aerial
surveys of Red Knots and other shorebirds during the winter in
Central and South America.
Note # 4. Other birds of interest on
Monday were 3 juvenile Bonaparte's Gulls, 2 adult Arctic Terns, 3
Yellow Rails, 22 migrating Bank Swallows, 3 Rusty Blackbirds, 2
Nelson's Sharp-tailed Sparrows (still actively singing), 4 Le
Conte's Sparrows (actively singing). The Ministry survey crew also
saw many young American Toads of the colourful Hudson Bay
subspecies, Bufo americanus copei, and a Painted Lady
(butterfly).

James Bay 9
August 2005 - Report #6 |
This is the sixth and final report from
Jean Iron who was surveying shorebirds along the south coast of
James Bay in northern Ontario for the
Ontario Ministry of Natural Resources.
The survey ended yesterday. Jean noted that water temperatures are
very warm in the coastal pools where shorebirds such as yellowlegs,
Hudsonian and Marbled Godwits were feeding. The Leasts and Pectorals
were around pool edges and along muddy creeks, whereas the
Semipalmated Sandpipers and White-rumped Sandpiper were feeding
mainly at the edge of the ebbing tide. The shallow tidal water is
also warmer this summer because of many hot sunny days. Most of the
juvenile Greater Yellowlegs were catching tiny fish in tidal pools
and along the tide line. Below is a list of the shorebirds observed
on Tuesday (Aug 9) about 20 km north of the mouth of the Moose River
near Shegogau on southern James Bay.
Black-bellied Plover, 1 heard in flight.
Semipalmated Plover, 23, mostly
juveniles.
Greater Yellowlegs, 283, 75% juveniles.
Lesser Yellowlegs, 95, mostly juveniles.
Hudsonian Godwit, 62 molting adults and
3 juveniles.
Marbled Godwit, 5 juveniles, most adults
may have left James Bay.
Red Knot, 11, most with much alternate
plumage. More on knots see # 1 below.
Sanderling, 5 worn and molting adults,
first juveniles expected soon.
Semipalmated Sandpiper, 4374, 60%
juveniles.
Least Sandpiper, 248 juveniles, 1 adult.
White-rumped Sandpiper, 7162 adults, no
two birds alike because of different degrees of body molt.
Pectoral Sandpiper, 117 adults, first
juveniles expected soon.
Dunlin, 1 adult
Note # 1. More on Red Knots: Yesterday I
talked to Mark Peck of the Royal Ontario Museum here in Toronto.
Mark is part of an international group from Canada, United States,
Brazil, Argentina and Chile who is studying the Red Knot. They are
doing field work on the breeding grounds at Southampton Island
(Nunavut) north of Hudson Bay. They are locating nests and
monitoring nest success, but their sample sizes are low ranging from
6 to 12 nests per year. Knot nests are difficult to find because
they have large territories and incubating birds sit tight in
cryptic habitat. They also are studying predation rates during high
and low lemming years. When lemmings are low, predators such as
jaegers and gulls prey more on birds. The group is taking blood
samples for DNA work (genetic diversity) and feather samples for
isotope analysis to determine the geographical areas used by this
population. Anyone seeing Red Knots with coloured leg bands and
flags can report sightings including numbers of adults and juveniles
to Mark Peck (peckm at rom.on.ca). As well, the Committee on the
Status of Endangered Wildlife in Canada (COSEWIC) has contracted Guy
Morrison, Research Scientist - Shorebirds, Canadian Wildlife Service
to prepare a status report on the Red Knot. This report will guide
COSEWIC in designating the Red Knot as Endangered, Threatened,
Special Concern, or Not At Risk.
Note # 2. Ontario Breeding Bird Atlas:
This is the final year 5 of the breeding bird atlas. Atlas crews
surveyed many blocks in northern Ontario
and along the coast of Hudson and James
Bay, will add much valuable information to our knowledge of breeding
shorebirds in Ontario. Publication of the Atlas is scheduled for
September 2007. To view preliminary maps http://www.birdsontario.org/atlas/map.jsp
Note # 3. Other birds of interest on
Tuesday (Aug 9) were 7 Sandhill Cranes, a light morph Rough-legged
Hawk at the Moosonee airport, 1 Yellow Rail, 35 Rusty Blackbirds,
and Savannah Sparrows were common along the coast. Three Belugas
(white whales) were seen from the helicopter at the mouth of the
Moose River.
Acknowledgements: Jean would like to
thank the Ontario Ministry of Natural Resources (OMNR) for the
opportunity to survey shorebirds during its study of coastal
habitats on James Bay. Jean will be submitting a report to the OMNR.
After yesterday's survey, Jean flew by
helicopter from Moosonee to Timmins. They saw two small forest fires
which OMNR crews were working on to put out before they got out of
control. With the hot weather and thunderstorms, the fire hazard is
high. The helicopter used for the James Bay surveys is now assigned
to fighting forest fires north of Thunder Bay (Lake Superior) where
the fire hazard is extreme. Today Jean is making the long 10 hour
drive from Timmins to Toronto. She'll be stopping every 75 km to
assess cone crops, birch catkins and mountain-ash berries. Tomorrow
she'll put shorebird photos from James Bay on her website:
