Six 3-day-old black swans look for food with their parents on a lake in the Park of the Ruins of the Yuanmingyuan(Garden of Ten Thousand Gardens) in Beijing October 19, 2009. Six young black swans were born on October 17 and 18 to two adult black swans in the park. The two adult black swans came and settled in the park in February 2008 and have given birth to 24 young black swans in the park since then. The young black swans will become black as they grow up.[Xinhua]
