You may get a chance to spot a nene on Hawaii's Big Island in the coming months, but wildlife experts are warning visitors to steer clear of the rare geese.
Nene -- pronounced nay-nay -- mate and nest December through April. Pairs of them can be seen flying overhead and grazing with their goslings.
Nene crossing signs are posted along roads where the native geese are known to congregate.
"Nene are most vulnerable to vehicles this time of year," Kathleen Misajon of the park's Nene Recovery Project said in a news release. "They are focused on eating and could be out foraging from dawn to dusk. They blend in with their surroundings, and in low-light periods, they are especially hard for motorists to spot."
Misajon also urged people not to feed the nene, because that can lure them out of the brush and onto roadways. Areas within the park where nene, the Hawaii state bird, are nesting may also be temporarily closed off.
