Not available. This representation exists with one or all sites, one or all years and a single species.

Comparison of the duration of migration : This graph compares the duration of migration in number of days between different key percentages of migration. It is possible to compare several sites on the same graph.
Not available. This representation exists with one or all sites, one or all years and a single species.

Comparison of migration dates : This graph matches key percentages of migration with calendar days. It is possible to compare several sites in the same graph.
Not available. This representation exists with a single site, all years and a single species.

Interannual trend : This interannual graph represents the evolution between annual totals.
Not available. This representation exists with a single site, one or all years and a single species.

Phenological trend : This graph represents the evolution of the percentage of migration. Key percentages are indicated by vertical red bars.

Daily evolution : This interannual graph represents the trend of dates and key percentages of migration.
Not available. This representation exists with a single site, one or all years and a single species.

Totals by hour : This graph represents the distribution of the total number of birds by hour. When a specific year is chosen, the average of all the years of the migration watch is shown in grey.
Not available. This representation exists with a single site, one or all years and a single species.

Seasonal phenology : This graph represents the distribution of the daily passage total (the decadary total is symbolized by red bars). If a specific year is selected, the average of all years is shown in grey.
Not available. This representation exists with a single site, one or all years and a single species.

Relative migration : This graph represents the distribution in daily percentage of migration (percentage by decade being symbolized by red bars). If a specific year is chosen, the average of all years is shown in grey.
Not available. This representation exists with a single site, one or all years and a single species.

Seasonal phenology (decade) : This graph represents the migration total by decade. If a specific year is selected, the average of all years of the migration survey is shown in grey.
Not available. This representation exists with a single site, one or all years and a single species.

Hourly mean per decade : This graph shows the mean number of migrants per hour over ten-day periods. When a specific year is selected, the mean number of migrants calculated over all years of record is depicted in grey.
Not available. This representation exists with a single site, one or all years and a single species.

Seasonal phenology (5-day period) : This graph shows the numbers of migratory individuals over 5-day periods. If a specific year is selected, the average of all years is shown in grey.
Not available. This representation exists with a single site, one or all years and a single species.

Hourly mean per 5-day period : This graph shows the mean number of individuals per hour over 5-day periods. When a specific year is selected, the mean number of migrants calculated over all years of record is shown in grey.
Not available. This representation exists with a single site, a single year and all the species.

Summary table : This graph represents the seasonal totals as well as the latest totals of the migration watch. The upper table represents the most significant species for the watchpoint.
Not available. This representation exists with a single site, a single year and all the species.

Migration synthesis : This graph is representing migration periods for each species at the site in a given year
Available. This representation exists with one or all sites, one or all years and all the species.

Observation effort : This table shows the observer pressure at the watchpoint for all years or day by day for a selected year.
Not available. This representation exists with all sites combined, one or all years and a single species.

Distribution Map : This map shows the relative importance of the watchpoints for a selected species. The dots represent the number of individuals per season.
