Deviation

Shows deviations from previous years'' observations for the last year seasons.
Only species with annual average larger than 5 are included. The table is intended to give indications of which species that have been particularly scarce or abundant in the past year. This is not processed data and many species have a variable occurrence at the observatory. The changes should therefore not be taken literally or referred to directly as documentation for population changes.
