March 2004
Despite the fact that the first year of our study into the effects of feral cats on hoiho populations on Stewart Island did not show high rates of predation, we still managed to obtain some useful data.

Unexplained Chick Losses on Stewart Island
March 2004
[Excerpt]The Yellow-eyed Penguin Trust has just completed the first year of a planned five-year study to measure the effects of cat predation on yellow-eyed penguins on Stewart Island's north-eastern beaches. But instead of cat predation, what we found was as yet unexplained high chick death rate.

Cat predation on Stewart Island
This research proposal covers a five-year study into whether the control of cats has a positive effect on the breeding success of yellow-eyed penguins on Stewart Island. One area will have as many cats killed as possible and another will be left as a control area. We are hopeful that this will show us that the fledging success in the targeted area is greater.
