Get off my land!
It sounds sweet, but it isn’t.
This Robin is giving out a complex multi-level message to all-comers.
Whenever you meet new people you assess them using the following criteria within less than half a second:
- Are they a threat?
- Are they from my tribe?
- Can I have babies with them?
Robins do the same. This Robin’s song may sound sweet.
But it’s message is:
“Get off my land unless you want my babies.”
