Found a free site to explain:

[Plants let out an ultrasonic scream when their leaves
are cut or they don't get enough water]

[Have you been ignoring your houseplants?
They may be filling your house with deafening clicks,
but these are too high for you to hear,
scientists have found.
A study, published in the peer-reviewed journal
Cell on Thursday,
found that plants can emit high-pitched clicks
when they are stressed by droughts,
infections, or cuts.

These noises are at about the volume
of a normal human conversation,
but they are so high-pitched that we
cannot hear them.

"Humans usually hear to 16 kilohertz.
These sounds are mostly between
40 and 80 kilohertz," Lilach Hadany,
senior author on the study and an
evolutionary biologist and theoretician
at Tel Aviv University, told Insider.

It's possible that these noises
can help some animals — like bats, moths,
and mice — get a sense of the condition
of the plant and of the plant species,
said Hadany.]

To be fair though, plants signalling each other isn't a new idea. Acacia plants warn each other when there's a grazer, etc.

They're eaten by giraffes and antelope, not ducks.

The trees release ethylene which "warns" nearby trees, and in response they in turn let toxicity seep into their leaves.
