Penguin Deaths in Golden Bay Spark Urgent Warning to Dog Owners

The Department of Conservation (DOC) has issued a stern warning to dog owners in Golden Bay following the discovery of nine dead little penguins (kororā) over a period of approximately two weeks. The incidents highlight a growing concern for the endangered species, with evidence suggesting dog attacks are the primary cause.

Most recently,three kororā were found deceased on Pakawau Beach. Authorities suspect a dog was responsible for their deaths. The concerning trend had already been noted with six other little penguins discovered on the nearby parapara Beach in the preceding twelve days, also believed to have been killed by dogs.

Acting Golden bay DOC operations manager, Shane Butland, emphasized the critical need for responsible pet ownership. “We are reminding owners to keep dogs on leads during the day and securely contained at night, especially in areas where penguins are known to be present,” Butland stated.

Little penguins, or kororā, are the world’s smallest penguin species, reaching only about 25cm in length when fully grown. Thay are currently listed as ‘At Risk – Declining’ due to a range of threats, including dog attacks, predation by introduced species, vehicle strikes, and general disturbance by humans.

Golden Bay ward councillor Celia Butler acknowledged that the situation is not new. “There is an ongoing problem with penguins being killed by dogs,” Butler explained. “A notable factor is that dogs are strongly attracted to the scent of penguins, and the birds are currently nesting, making them particularly vulnerable.”

Butler also pointed out that council bylaws require dogs to be under control at all times, which includes preventing them from roaming unsupervised at night. “When people allow dogs to roam at night, they are breaking the bylaw, but it is indeed very arduous to identify whose dog is responsible,” she added.

It is a reminder that kororā are fully protected under the Wildlife Act, and any harm or killing of these birds is illegal.

What are the potential environmental factors contributing to the rise in penguin deaths in Golden Bay?

Recent Spike in Penguin Mortality – What’s Happening?

Golden Bay, New Zealand, is experiencing a concerning surge in penguin deaths, particularly affecting the Little Blue penguin (Kororā) population. Reports from local wildlife rescue organizations adn concerned citizens indicate a significant increase in deceased penguins washing ashore along the coastline. This isn’t a new issue,but the current rate of mortality is alarming,prompting investigations into the underlying causes. The situation is impacting penguin conservation efforts and raising serious questions about the health of the marine ecosystem.

Identifying the Affected Species: Little Blue Penguins (Kororā)

The majority of the penguins affected are Little Blue Penguins, the smallest penguin species, native to New Zealand and Australia. These penguins are particularly vulnerable due to thier size and reliance on near-shore feeding grounds. Their breeding colonies are scattered along the Golden bay coastline, making them susceptible to localized environmental changes. Understanding Little Blue Penguin behaviour and habitat is crucial to addressing the crisis. Other penguin species, though less frequently reported in this specific event, coudl also be at risk.

Potential Causes of Penguin Deaths

Several factors are being investigated as potential contributors to the increased penguin mortality. It’s likely a combination of these stressors, rather than a single cause, is responsible.

Avian Malaria: Recent research suggests avian malaria, transmitted by mosquitoes, is playing a role. warmer temperatures are expanding the range of mosquitoes, exposing penguins to the disease.

Food Scarcity: Changes in ocean currents and water temperatures can impact the availability of small fish and squid, the primary food source for penguins. Penguin diet is directly linked to their survival rates.

Predation: While natural predation exists (by seals, sharks, and seabirds), an increase in predator activity or changes in predation patterns could be exacerbating the problem.

Plastic pollution: Ingestion of plastic debris is a known threat to penguins, causing internal injuries and malnutrition. Marine plastic pollution continues to be a significant issue.

Oil Spills & contamination: Though no major spills have been reported recently, historical contamination and smaller leaks can still impact penguin health.

Harmful Algal Blooms: Blooms can produce toxins that affect the food chain and directly harm penguins.

Climate Change Impacts: Rising sea temperatures, increased storm frequency, and altered ocean currents all contribute to a less stable habitat for penguins.

The Role of Avian Malaria – A Growing Threat

Avian malaria, previously uncommon in New Zealand, is now being detected in penguins with increasing frequency.The disease weakens penguins, making them more susceptible to other threats. Warmer winters and increased rainfall are creating ideal breeding conditions for mosquitoes, expanding their range and increasing the risk of transmission. Avian disease outbreaks are a growing concern for wildlife populations globally.

What is Being Done? – Rescue and Rehabilitation Efforts

Local wildlife rescue organizations, such as the Penguin Rescue Golden Bay, are working tirelessly to rescue and rehabilitate sick and injured penguins.

Rescue Operations: Teams patrol beaches, collecting penguins exhibiting signs of illness or injury.

Veterinary Care: Penguins receive veterinary treatment, including fluids, antibiotics (when appropriate), and nutritional support.

Rehabilitation: Healthy penguins are released back into the wild, often after a period of monitoring.

Disease monitoring: Samples are collected from deceased penguins to identify the causes of death and track the spread of diseases like avian malaria.

Community Involvement: Local residents are encouraged to report sightings of sick or injured penguins.

How You can definately help – Supporting Penguin Conservation

There are several ways you can contribute to penguin conservation efforts in Golden Bay and beyond:

Report Sightings: If you find a sick or injured penguin, contact Penguin Rescue Golden Bay immediately.

reduce Plastic Use: Minimize your plastic consumption to reduce marine pollution.

Support Conservation organizations: Donate to organizations dedicated to penguin research and rehabilitation.

responsible Tourism: When visiting penguin colonies,follow guidelines to minimize disturbance.
