What happened to the birds on Easter island?

On Easter Island, many bird species faced extinction due to a combination of environmental changes and human activities. The arrival of the Polynesians led to habitat destruction through deforestation and the introduction of invasive species, such as rats, which preyed on bird eggs. Overhunting also contributed to the decline of various bird populations. By the time European explorers arrived in the 18th century, many native birds had already disappeared.
