New York City's most famous groundhog, Staten Island Chuck, predicts it will be an early spring.
Mayor Michael Bloomberg was on hand to help. He held up the groundhog and shouted: "Go Giants."
Chuck is at odds with Pennsylvania's pride and joy.
Punxsutawney Phil saw his shadow - predicting six more weeks of winter.
Chuck - whose formal name is Charles G. Hogg - made his prediction at the Staten Island Zoo.
Bloomberg handled him with heavy gloves. They became part of the mayor's fashion attire for the annual event after Chuck chomped on his finger in 2009.
Tradition holds that if the groundhog sees its shadow, winter could last six more weeks.
