Usually 15,000 to 24,000 breeding pairs of emperor penguins flock yearly to a breeding site at Halley Bay, considered a safe place that should stay cold this century despite global warming. The breeding pair population has increased significantly at a nearby breeding ground, but the study's author said the numbers are nowhere near those missing at Halley Bay. Normally about eight per cent of the world's emperor penguin population breeds at Halley Bay, Trathan said. While that's encouraging, it doesn't make up for all that was lost at Halley Bay, Trathan said. The number of emperor penguin births are strong at nearby breeding areas, but scientists say, it doesn't make up for the losses at Halley Bay.
