Summary of the changes (in days per year) of start, peak, end date of the main migration period and migration window for 30 bird species migrating through the island of Ponza between 2002 and 2019.
Fig 1.
Trends of change in start, peak, and end date of the main migration period of 30 bird species migrating through the island of Ponza between 2002 and 2019, subdivided into wintering groups.
Every dot represents the passage date of a single species in any given year. Patterns for all species singularly are shown in S1 Fig.
