Help Help

  • To view distribution maps of a bird species, enter part of the common or scientific name in the search box, then choose from the list of results that appears.
  • When the species results load, you will see Current records at a low resolution.
  • As you zoom into an area of interest, the map will automatically change to a progressively higher resolution of each record, if recorded at a high enough resolution.
  • Species recorded at a low resolution will disappear at zoom levels which require more accurate grid references.
  • Darker squares indicate more records of that species within that grid square.
  • The mapping options menu on the right allows you to display Current (by default), Historic or All records, and lets you lock the resolution.
