DoC Shocked as Ducks Captured Eating Native Chicks Alive

The alarming behavior of mallard ducks has raised concerns among conservationists in New Zealand. Recently, ducks were observed capturing and consuming native pūteketeke chicks alive. This unexpected threat to the vulnerable species has prompted immediate action from the Department of Conservation (DoC).

Shocking Mallard Duck Behavior

According to DoC experts, mallard ducks predominantly consume vegetation and small invertebrates. However, reports surfaced of these ducks targeting the vulnerable pūteketeke nests, located near an outlet creek.

Behavior Not Previously Documented

This predatory behavior was previously unknown among DoC researchers. Field observations revealed that the ducks were scouting for chicks to prey upon. Nelson, a DoC representative, noted that adult pūteketeke did not recognize ducks as threats.

• Three mallard ducks were observed in the area.
• This behavior parallels a 2017 incident reported by Cambridge University regarding mallard ducks in Romania.
• The Romanian ducks were noted to have attacked the chicks of two different bird species.

Nelson highlighted the importance of citizen involvement in conservation efforts. A concerned community member reported the incident to DoC, providing photographic evidence, which validated the observations.

Encouraging Public Engagement

DoC encourages the public to remain vigilant and to report any sightings of at-risk native wildlife. The pūteketeke, known as the Australasian crested grebe, is classified as nationally vulnerable and is native to New Zealand.

Last December, campers and boaters at Lake Benmore received requests to be alert for this bird species due to previous disturbances to nests. With approximately 40 to 50 nests reported each breeding season, the nesting habits make them vulnerable to predators.

Immediate Measures Taken

In response to the recent threat, DoC staff successfully captured the three mallard ducks involved. They were humanely euthanized to prevent further predatory behavior. Rangers will continue monitoring the area to ensure no additional ducks exhibit similar actions.

The efforts to protect the pūteketeke gained attention when comedian John Oliver advocated for the species in 2023, allowing it to win the Bird of the Century title. Historically, these birds thrived across New Zealand, but today they are primarily found in the South Island, specifically in lakes within Canterbury and Otago.

How to Help

Anyone who encounters injured or vulnerable native wildlife is urged to contact DoC at 0800 DOC HOT (0800 362 468). Public awareness and engagement are crucial in safeguarding New Zealand’s unique wildlife.
