The results on this page are only showing the population indices for the project "Canadian Migration Monitoring Network". To view population indices from additional projects, you can use this page.
The Seasonal abundance tool allows you to display the migration phenology of selected species at one or more sites or regions, for selected months of the year. You can select multiple areas or species by holding the CTRL key. For more information about this tool,
Seasonal abundance graphs are plots of the daily mean log(count) across years sampled at a location (e.g., Canadian Migration Monitoring Network station).
Options are available to display a LOESS smoothed line of the percent of years the selected species was present each day of year, and the raw percent of years the station was in operation during each day of year (i.e., station coverage).
Migration windows show the boundaries of the spring and fall migration window, and are shown only if the species was analyzed during a particular season. The bounds of spring and fall migration windows were restricted to those days of the year when the station operated during at least 50% of total years in operation.
