Is there a specific reason for calling it BDD as oposed to TDD?

Until now I've only been used to hearing about TDD - Test Driven Developent in relation to using Jest and Mocha. What is the difference between BDD and TDD or is it simply a case of naming preference?

BDD (Behavior Driven Development) is also a test-first approach like TDD (Test Driven Development), but differs by testing the actual behavior of the system from the end user's perspective.

The BDD approach is an extension of TDD and is intended to avoid false results that can occur with TDD.
