1996 – 2005
K. Martin, principal investigator
We began this project in 1996. Initially, we collected data on the use of the alpine by migrating birds in the course of other alpine field work. In 1998-2000 we conducted a more focussed study on alpine use by birds during fall migration in south-central British Columbia. Fall migrants were intensively captured and banded in the Vancouver area from 2001 through 2005.
During fall migration, the alpine provides rich food resources. In three years of surveys in mainland BC, we have observed over 110 bird species. We observed a peak in avian diversity during early- to mid-September.
Many bird enthusiasts are aware that migratory birds are found in the alpine during autumn migration. However, this phenomenon has not been well-documented in the ornithological literature. We have been conducting research on the use of alpine habitat by migratory birds.
The alpine experiences a period of intense productivity in late summer and autumn.
Insects emerge in late summer, and the alpine meadows flower in August and September.
We have compiled tables of species that use the alpine and subalpine, and a report on avian use of the alpine during migration. Links are found on the documents page.
