It was hard to tell the difference between the two different terns until I photographed the birds at different locations.The first are the Forester's tern with an orange black tipped beak and longer tail projection that can be seen in the second series of photos. Please let me know if you have different opinion as I am just a beginner birder.
The first were photographed at Val Marie near Regina. The second series are from Chaplin IBA Saskatchewan.
