Although groundhogs live for around 10 years in captivity, Phil loyalists insist there has only been one Punxsutawney Phil since his first appearance in the 1880s. According to the official website of the Punxsutawney Groundhog Club, Phil is given a sip of special groundhog punch every year, which extends his life and allows him to keep making predictions.
When will he make his prediction on Groundhog Day 2011? In recent years, the prognostication has come at about 7:30 a.m. Eastern time.
