I expected this to be about sea gulls. I think they're smarter than most people give them credit for; I've seen them open zippered bags on the beach, and they have a sort of fearless approach to humans that reminds me of the way crows behave around humans. Apparently tool use has been observed in some gulls so maybe the the article title is overstating the matter a little (unless gulls aren't considered seabirds?): https://bioone.org/journals/waterbirds/volume-29/issue-2/1524-4695(2006)29%5b233%3aTICABB%5d2.0.CO%3b2/Tool-use-in-Charadrii--Active-Bait-Fishing-by-a/10.1675/1524-4695(2006)29[233:TICABB]2.0.CO;2.short https://bioone.org/journals/waterbirds/volume-29/issue-2/152...
