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.
