| Abstract: | Observations and records maintained by the Hudson's Bay Company at York Factory and Churchill Factory on Hudson Bay between
1714 and 1825, serve as the source of information for a study of changes in the date of arrival of geese as a phonological
indicator of climatic change. Changes in the migration pattern of geese are reflected in the changing date of arrival at the
same location over a long period of time. Variations in this date are determined to be a function of southerly or tailwinds
in the northward spring migration. |
