The sounds of the ecosystem were the original orchestras. The origin of music on earth. May it sing forever.
This is also a great source of recordings

Surely communication has its origins with animals consistently correlating a signal (physical, vocal, etc.) with an action (aggression, submission, etc.).
Their pattern-recognising brains naturally picked up on the new pattern.
Alarm calls
Animals will rely on other animals. Rabbits will rely on the crows to alarm them if a potential predator is coming. It's a network.
Herbivores especially are in this network. In contrast, when a predator shows up, everyone else leaves.
Predators are unwelcome in their own environment. They are constantly harassed by birds.
When a predator walks into a room, everyone else leaves. They stand apart from the rest of the ecosystem.
Co-operation
And predators might follow scavengers who alert them to potential food or carcasses. Scavengers themselves may be unable to tear the skin properly or whatever.
Mating calls
Every little noise in time is filled in this environment. It's like a Hong kong street.
A new little cherper has a marketing problem.
Listen to nature fully and it's so incredibly rich. Literally every nanosecond in any environment is filled with sounds.
The sound of a place tells you about its whole ecosystem. Well except for the hidden ones.
Often, every little noise in time is filled in this environment. It's like a Hong kong street.

What are the strategies?
Expand into new frequencies - Many sounds are outside the range of human hearing
E.g. this recording of the Panaman rainforest at night has been slowed down to reveal sounds outside of the range of human hearing,
Amplify it with your surroundings - frogs love drains
Territorial calls
A dogs bark gives a huge indication to its power.
Many animal's call is a reflection of how they fit in their ecosystem. Wolves, gorillas, tigers, lions, crocodiles.
