Origin
of Snow Geese seen on the DVOC trip to Bosque del Apache, December 2004
by Colin Campbell
I frequently read neckbands of members of the Greater Snow Goose flocks which
winter in Delaware and send them in to the USGS. They invariably return the
information that all banded birds are female and derive from the breeding
flock on SW Bylot Island, Northwest Territories (NT), at the north end of
Baffin Island at about 73 deg N. I was interested therefore to learn of the
origins of the neckbanded Lesser Snow Goose and Ross's Goose which were read
via telescope during the Club's trip to Bosque del Apache, NM on the 6 December
2004. All were banded by Dr R.T.Alisauskas of Saskatoon.
The results are tabulated below, broken down by age and sex (aren't we all?).
| LESSER SNOW GOOSE | ||||
| Band No. | Sex | Age | Date banded | Where banded |
| 5RO | F | 5+ | 08.01.00 | 9m se Johnson Point, NT |
| 5AK | M | 5+ | 08.02.00 | 30m s Johnson Point, NT |
| X14 | F | 4+ | 08.04.01 | nr Simpson River, NT |
| 8RB | M | 2+ | 08.03.03 | 8m s Johnson Point, NT |
| 5PB | F | 2+ | 08.07.03 | 8m s Johnson Point, NT |
| 4XC | M | 1+ | 08.09.04 | nr Simpson River, NT |
| ROSS'S GOOSE | ||||
| Band No. | Sex | Age | Date banded | Where banded |
| J6P | F | 3+ | 08.03.02 | 30m s Johnson Point, NT |
| 8EX | M | 3+ | 08.07.02 | nr Simpson River, NT |
| TY5 | F | 2+ | 08.03.03 | 8m s Johnson Point, NT |
The results show that both species came from two breeding regions, denoted
as Johnson Point, NT and Simpson River, NT. Johnson Point is on Banks Island
(on the Prince of Wales Strait, separating Banks from Victoria Island) at
72 deg N 118 deg W. I have not been able to determine the precise location
of the Simpson River; there's Fort Simpson, Simpson Bay, Simpson Island, Simpson
Lake, Simpson Strait ..... but no River, as yet. As two of the 'date banded'
from the two locations are just 4 days apart, the mysterious Simpson River
can't be too far from Johnson Point, probably on Banks Island too.
