Sightings 2015

red is a rare or scarce species
green is early (first) or late sighting
blue is a high count
blue is a count that exceeds the 1% level

The 1% level is an indicator of the importance of a wetland area. If 1% of the total North-West European population of a bird species is present on a regular basis, the site is of international importance.
