A bird that can sing and won't sing, must be made to sing.

Understand the thought

Meaning in plain English

The saying demands that a capable person contribute even when unwilling. The bird’s song makes the demand vivid but does not establish a right to force performance.

What the words are saying

Ability is treated as reason enough to compel action. A careful reading asks whether a responsibility was freely agreed and whether the person has reasons or limits others have overlooked. Talents can be offered voluntarily, and declining an optional contribution is not itself a fault. The useful discussion concerns a particular commitment and appropriate support rather than access to someone’s skills on demand.

Everyday example

An organiser asks why an agreed contribution has not happened and considers a revised arrangement instead of pressuring someone into an optional performance.

When to use it

Use it critically to distinguish agreed responsibility from coerced contribution.
