As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

The Extinction of the Kauai ʻōʻō



The Kauai ʻōʻō was driven to extinction due to the presence of invasive species and habitat destruction but for other native forest birds conservation efforts can help.

The Hawaiian Islands are a unique and wondrous hotspot of biodiversity, but due to the introduction of invasive predators and habitat destruction, many of these birds have been driven to extinction. The Kauai ʻōʻō is a prime example; the small black and yellow bird once thrived from the shores of Kauai up to through the rugged mountains but the bird was last seen in 1985 and potentially last heard in 1987. Dr. Jim Jacobi recounts his experience of seeing the last remaining ʻōʻō on a trip in 1984 as he says:

It was a beautiful day as I recall. We started off from this camp and it takes about an hour to go from where we were camped to down to the stream. We stopped there and started to listen.”

As they listened and recorded the sounds of the forest, the ʻōʻō called and flew onto a nearby branch. When the ʻōʻō flew away, Dr. Jacobi replayed the sound and suddenly the bird returned. He soon realized the bird was responding to a call he had not heard in a long time.

Today, the Kauai ʻōʻō is extinct but other native forest birds such as the I’iwi are still around, but face the threats of invasive species and climate change. Luckily, conservationists are dedicated to ensuring a thriving future for these rare birds. Conservationists are hopeful that by working to remove invasive species and use captive breeding programs to bolster populations they can help these forest birds fill the forests once again. The ʻōʻō serves as a reminder to strive to prevent extinctions of these endemic birds.
