Little Penguins use of Perth metropolitan waters exposes them to risk of injury from watercraft
The rapid growth of urban areas near Little Penguin colonies on Penguin and Garden islands in Perth, Western Australia, potentially increases their exposure to various threats. To identify the possible range of threats at sea, the foraging ranges and diving behaviour of the penguins have been studie...
