The Kaua'i finch (Telespiza persecutrix) was a type of bird that is now extinct. It belonged to the finch family, called Fringillidae. This bird lived only on the Hawaiian islands of Kauai and Oahu. We only know about it from its fossil bones. It probably died out before Europeans first arrived in Hawaii in 1778.
What the Kaua'i Finch Looked Like
The Kaua'i finch was a small bird, about 5½ inches long. That's about the length of a pen. It had a very strong, blunt beak. This beak was probably perfect for cracking open tough nuts. It might have also helped the bird eat flowers, like the 'ōhi'a lehua blossoms.
Its strong beak could help it digest tough plant parts, like the cellulose found in plants. Scientists also think that insects might have been part of its diet. The Kaua'i finch was thought to live in high mountain forests. However, many of its fossils have been found in lower areas of the islands.
Why the Kaua'i Finch Disappeared
Because this bird became extinct so long ago, we don't know much about it. We only have a few bones found in caves to study. It seems the Kaua'i finch started to disappear when the first Polynesians settled in the islands.
These early settlers cleared some land for farming. They also brought new animals and plants with them. These new species were called introduced species. The native Hawaiian birds, like the Kaua'i finch, had no way to defend themselves against these new threats.
The Kaua'i finch was likely extinct about 500 years before Europeans reached Hawaii. Fossil records show their numbers dropped very quickly in the early 1500s. It's thought that when these birds visited lower parts of the island, it might have caused their downfall. They could have caught bird diseases or been bothered by pests there.
Finches once lived on all the larger Hawaiian islands. The highland finch seemed to survive longer than the Oahu finch. Today, only about 60% of Hawaii's land is still natural. Many bird diseases and parasites are still a big danger to Hawaii's native forest birds.
