This map was created using satellite location data from all of our tagged terns to show the areas used between 01 January and 31 March, 2016. The red areas indicate the places where the probability of finding an individual tagged tern is 50% and the orange encompasses the area where that probability is 90% (note: higher percentage areas also include the lower percentage areas contained within). Take a look at the previously posted animation to see how our featured terns fit into the overall distribution of the wintering grounds.
