Beaverhill Bird Observatory - Hairy Woodpecker Wing

Due to the COVID-19 pandemic, the BBO is not accepting volunteers at this time and we will not be banding birds until further notice. We ask that visitors respectively stay outside of our buildings, as we are happy to talk and visit with you in the great outdoors!

Migration Monitoring

Initiated in 1984, migration monitoring is the longest running program established at the BBO. Migration monitoring is a means of documenting changes in abundance of northern-nesting species across broad geographic scales that are relatively inaccessible for breeding season surveys

The program became fully standardized in 1990 and 13 mist-nets are currently operated at the BBO.
Banding starts a half-hour before sunrise and runs for 6 hours
Spring monitoring occurs: ~ April 1 to June 9th
Fall monitoring occurs: ~ August 1 to October 10th
Banding occurs during standard weather conditions with no significant precipitation
BBO reports daily estimated totals, which are combinations of: standardized banding, daily census, and casual observations.

These methods are also used at over two dozen stations across Canada who belong to the Canadian Migration Monitoring Network (CMMN), which BBO joined as a full member in 1992.

CMMN is a cooperative venture among:

Independent migration monitoring stations, such as the BBO, who collect data
Canadian Wildlife Service (CWS), who regulates permitting
Bird Studies Canada (BSC), who carries out trend analysis

Migration monitoring requires substantial effort by skilled staff and volunteers, and ongoing financial support for infrastructure and salaries.
