Rescuers were racing to save hundreds of pilot whales in New Zealand's picturesque Golden Bay on Friday, after one of the country's largest recorded mass whale strandings. Up to 300 whales have died and volunteers were trying to send more than a hundred others back out to sea. A conservation department worker noticed the whales washed ashore on Thursday evening, but the government agency decided against a night rescue effort for fear volunteers would be injured by the whales in the darkness.
