March 26,
2003: We will be archiving information about this swan
shortly since we are no longer monitoring the animal.
November
4, 2002: No more to add on this bird at this time - still
have received no additional radio signals.
September
24, 2002: Great Bear Lake. Unfortunately, we have not
received any new radio signals since July 23 and we think the
radio may have finally quit working. This swan was captured and
fitted with a transmitter on February 27, 2001 in Essex County,
so we have been tracking her for a year and 5 months. We
obtained a lot of valuable movement information from this swan.
We monitored her migration north in the spring of 2001, her
nesting location in 2001, her migration south back to Virginia
in the fall of 2001, her winter activities in Virginia during
the winter of 2001-2002, her migration north in the spring of
2002, and her nesting location in the summer of 2002. The
battery life for these radios is 1 - 1.5 years, so it lasted for
about as long as we could hope for.
June 12 -
July 23, 2002: Great Bear Lake. She has remained in
this location for the past 6 weeks and we assume she is nesting
here again this year.
May 26 –
June 12, 2002: Great Bear Lake. She has traveled
another 300 miles northwest to the western side of Great Bear
Lake. She is located in the Smith Arm branch in the same area
where she was last summer. She spent the entire summer of 2001
here and did not leave until late September. She probably nested
and raised a brood of cygnets here, although we were never able to
obtain a visual observation of her this past winter to confirm
this. It will be interesting to see if she stays in the same area
again this year.
May 21,
2002: Lac La Martre: She made another quick stop in the
area around Lac La Martre. She has moved into the boreal forest
region and appears to be on the same track she followed on her
migration last year (see archived log above from last year). She
is probably waiting for the weather to clear before she proceeds
further north.
May 17,
2002: Great Slave Lake: She traveled another 650 miles
northwest to the western end of Great Slave Lake at the origin of
the MacKenzie River in southern Nunavut (Northwest Territories).
Great Slave Lake is one of the largest lakes in northern Canada.
She stopped here only briefly before moving slightly further
northwest (150 miles) to the area around Lac La Martre.
May 8-13,
2002: Central Saskatchewan, Canada. She moved ~700
miles northwest into central Saskatchewan and is located just
south of Lac La Ronge. She is located north of the prairie pothole
region on the southern edge of the temperate forest zone. There
are larger, more permanent water areas here and she is probably
staging on a large pond in this area.
April 12-30,
2002: Fargo, North Dakota. This swan moved 450 miles
west and spent 2-3 weeks in the Red River Valley on the North
Dakota-Minnesota border. She spent a couple weeks here last year
around this same time. Several of our other swans are also in the
Red River Valley, which appears to be a very important migratory
stopover for these birds.
April 7,
2002: Sturgeon Bay, Wisconsin. She moved 200 miles west
and is located near Sturgeon Bay on the western side of Lake
Michigan.
April 3,
2002: Lake Huron, Michigan. She moved 100 miles west
across Lake Huron and is now located in the south end of Saginaw
Bay near Bay City, Michigan.
March 17-21,
2002: Lake Huron. She moved 200 miles northwest of her
last location to the eastern side of Lake Huron near the town of
Grand Bend in Ontario, Canada. Interestingly, she had stopped in
this area last year on her migration north. It will be interesting
to see if the timing and route of her migration will be the same
this year. Two of our other satellite-equipped swans (#33892 and
33894 - see below) have also stopped in this area and are located
within 20 miles of this bird.
March 12,
2002: Pennsylvania. The swan has started the first leg
of its long spring migration to its arctic nesting grounds. We
received a location in central Pennsylvania near the town of
Grassflat, 300 miles northwest of her previous location. We don’t
know if she stopped at this location or if she was in route up to
the Great Lakes region. We have not seen any of our other swans
stop in this area.
December 28,
2001 - March 11, 2002: Northern Neck of Virginia. The
swan has remained on the Northern Neck of Virginia. This area is
bordered by the Potomac and Rappahannock Rivers and includes fresh
and tidal marshes, and adjacent agricultural fields. This region
is an important wintering area for swans and generally has between
2-6,000 swans each year. She is using the same marshes and
agricultural fields near where she was caught in February 2001. |
