Groundhog Day

On February the 2nd,  it´s a special in the EEUU, it´s the day when they check if Spring is coming soon. A particular animal, a Groundhog called  "Phil",  looking at his shadow,  can predict the upcoming weather. 
He lives in a burrow, hibernates and he when spring is nearby he goes outside and predict the weather.
Funny!! 
It´s similar to our tradition with storks...
