* A type of bird: It's the most common meaning and refers to the New Zealand brown kiwi (also known as the North Island brown kiwi), which is a flightless bird endemic to New Zealand.
* A tool: Less commonly, "weka" can also refer to a tool or implement, particularly in a specific context. However, this usage is not as widespread as the bird meaning.
Therefore, when you see "weka" in Māori, it is most likely referring to the bird.
