A short SF story with an anthropologic angle. A team of anthropologists devised an experiment placing, as I recall it, 100 babies on an island (tended initially by machines).
The island was wired with cameras and microphones to observe kids as they grew up (ala Truman Show). The kids developed a language, ability to care/tend for themselves. A storm ripped out cameras and microphones in one small section of island. The kids somehow became aware they were being observed and used that unmonitored area for reasons I cannot recall - meetings, planning.
I can’t quite remember the ending, but seems aliens showed up and took the kids away. I would like to reread the story. I believe I read it in an anthology in early 70s or late 60s.
