The Tropical Finch was introduced to Woodsvale in 1998. Many people wanted to have a
cute and colorful bird as a pet. Some people couldn’t take care of the birds, so they
released them into the forest around Woodsvale. Since that day, the birds have been
spreading across the country. They eat seeds from farmer’s fields and fruit from trees.
They spread very quickly, much faster than many of the native birds. There are now more
than 120 million of them in the wild. They are a big threat to the ecosystem of
Woodsvale. There isn’t enough food for all the different birds and insects. Also, new
plants cannot grow in the places where the birds live. They eat the seeds before they can
grow. Since last year, some farmers have been trying to kill the birds with poison.
However, the birds spread too quickly to control their populations well.
