Canadian Migration Monitoring Network


The Canadian Migration Monitoring Network (CMMN) involves the cooperation of many bird observatories across the country. Birds Canada provides standards for data collection and computer software to aid with migration counts, and developing analysis programs to calculate trends automatically using the data from each station. The stations are actively involved with counting and banding birds across the country and much of this work is done by volunteers. You can find out more about the CMMN and the member stations by visiting the main CMMN web site

This purpose of this site, is to provide results of CMMN population trend analysis and various other data summaries that you can use:
•    Annual and seasonal population trends can be used to generate population trend graphs and get estimates of population changes based on data from various CMMN stations.
•    The data summary page can be used to generate species lists with seasonal abundance.
•    This site can also be used to access descriptive metadata hosted on behalf of the CMMN members.
•    You can also use this site to download or request raw data from participating CMMN member stations for your own analyses or needs.

We expect to continue to work on the development of other interactive tools that use CMMN and other data as part of Birds Canada's involvement in the Avian Knowledge Network.
