The green broadbill, Calyptomena viridis. The species was native to the island of Sumatra in Indonesia, and was last seen in the wild in the early 20th century.

The green broadbill was a small bird, measuring approximately 15 centimeters in length. It had a striking green plumage, with a black head and tail, and a red bill. The bird was known for its distinctive call, which was described as a loud, nasal "wheeee-wheeee."

The green broadbill was a forest-dwelling bird, and it was believed to have lived in the lowland rainforests of Sumatra. The bird was considered to be a rare and elusive species, and very little is known about its natural history or behavior.

The exact cause of the green broadbill's extinction is unknown, but it is believed that habitat loss and hunting played a major role.

The lowland rainforests of Sumatra have been heavily logged and cleared for agriculture, leaving very little suitable habitat for the bird. Additionally, the bird was hunted for its feathers, which were highly valued for use in traditional headdresses.

Despite being extinct, the green broadbill remains an important symbol of the loss of biodiversity caused by human activity. The bird serves as a reminder of the need to protect and preserve the remaining natural habitats and wildlife on Sumatra, and around the world.

Effort for conservation can be made by preserving the remaining habitat of the bird and by promoting sustainable use of natural resources in the region.

Education and awareness campaigns can also be implemented to educate people about the importance of protecting endangered species and preserving the environment.

In conclusion, the green broadbill was a unique and beautiful bird that was once found only on the island of Sumatra.

Unfortunately, due to human activities such as habitat loss and hunting, the species has become extinct. It serves as a reminder of the impact of human activities on the environment and the importance of conservation efforts.
