Forster's Tern: Tumbling from the sky

On a gray May Saskatchewan day, this white tern tumbled from the sky into a slough and caught — I wonder what? The tern's black-tipped orange beak seems to be holding something dark. A fish, perhaps?

This has been identified as a Forster's tern for several reasons:

1. It looked almost white;
2. Its tail is luxuriously long and beautiful — a give-away sign;
3. Several have been noted here recently.
