CLOSED: Forsters Tern?

Hi, is this a young Forsters Tern?

Caspian Tern

Well Okay, I'll get this figured out. Thank you - new bird either way

Forsters Terns can you see the difference especially the size of the bill??

Caspian Terns Resin can explain differences in more appropriate terms

Yep, Caspian Tern; the key points are the big heavy bill (like a carrot!) and large size (twice the size of Forster's), and also when in winter plumage, a more diffuse black head cover, unlike Forster's white head with a sharply defined black eye patch.

Thank you everyone - I got the difference now, it's finding out those key factors that are so helpful. The book I'm using did not explain it well.
