Endangered goose struck, killed by vehicle at park


Officials at Hawaii Volcanoes National Park report that a female nene, which is a Hawaiian goose and the state bird, was run over and killed by a car early Friday morning along Chain of Craters Road.

According to a written statement from the park, her mate remains near the site. The young pair was preparing to nest.

Park officials are urging motorists to slow down and to watch out for the endangered nene while driving on Highway 11 and other park roadways.

The park has placed nene crossing signs on roads where birds are known to congregate or cross, and where vehicle kills occur most frequently. Drivers are urged to pay attention to the signs and proceed cautiously.

“It’s imperative that drivers use caution throughout all nene crossing zones. It is understandable that people get complacent when they do not see nene in these areas for a long time; however, the park strongly urges motorists to pay attention to the signs and slow down,” said park wildlife biologist Kathleen Misajon.

Incidents of people feeding nene also have contributed to recent vehicle kills, Misajon said.

On Oct. 1, a 16-year-old male — a father of three fledglings last season — was killed by a vehicle along Highway 11, one mile outside of the park’s Ka‘u boundary. He was likely drawn to this location by feeding, which continues to be a problem at this site, attracting more nene to the roadside and increasing their odds of becoming the next road kill.

“Nene have significant threats to contend with, from predation by cats, mongooses and other introduced predators, to loss of habitat made worse by drought conditions. This species is really fighting an uphill battle. We ask the public to help us rebuild nene populations by minimizing vehicle-related nene deaths,” Misajon said.

As nesting season begins, nene, particularly females, are focused on eating. They must build up enough body fat to produce eggs and sustain them through the 30-day incubation period. As a result, females and their watchful mates are out not only during the day, but are also foraging at dusk and dawn and even throughout the night when the moon is bright.

Due to recent drought conditions, the vegetation is particularly dry at many of the favored breeding sites, pushing nene to move further afield in search of adequate food. Unfortunately, rain runoff from the pavement, combined with ground disturbance along road edges, often makes for lush grassy strips along roads, enticing birds to feed in dangerous spots.

Furthermore, nene may be difficult to see along roadsides because their coloring often blends in with the surrounding area.
