I just watched two adult Bald Eagles in hot-pursuit of a lone Brant.
I don't think I've ever seen Bald Eagles take a bird in flight. (I've seen them take out grounded birds, some as large as Canada Goose now and then).
The Brant looked so small in comparison, I first thought it was a tern or a teal. But that was just my perception given the unlikely combination of species.
The eagles looked like a tag team cutting off the Brant on each twist and turn. They appear to be a bonded pair that has been around for a few days, occasionally fending off a potential territorial intruder.
Although they all flew behind a leafy tree and I could not witness the get-away, I could tell that the eagles came up empty since they soon perched together in a neighbor's yard doing their loud eagle chirping.
A small group of Brant flew down river shortly afterwards, and I hope that lone goose joined forces with them to continue on to the coast.
