Where have Gulls been?
The App registers the location of your observation either you have location allowed on your device or you enter the location manually (you can do either and either is fine). That allows us to look at the spatial spread of the observations. This map is publicly available and you can look at an up-to-date map of where gulls have been reported here and click on Map in the upper right corner.
Among the buttons in the upper right corner of the map, click a button furthest down on the list (the 'star') and on the menue that comes up change from clusters to markers to see individual datapoints. By using the + symbol in the upper right corner of the map you can zoom into a particular area and you can see where gulls have been recorded in your area.
