"Southern Migration" Original Pastel 16" x 22" SOLD The Big Dipper is the first star pattern that amateur astronomers learn to identify because it is unmistakable. It is actually part of the constellation Ursa Major, the great bear. It's position shifts during the year - from close to the horizon in autumn as depicted in this painting, to nearly overhead in spring. This painting is a representation of our traditional fall migration as thousands of waterfowl make the long journey South with Ursa Major at their backs.
