Geese …………

Why do geese mate for life? Less for love than for
survival. The pair bond appears vital to the success
of migration and nesting-Time is precious for
geese. Many must migrate thousands of miles to
reach their nesting grounds above the Arctic Circle
and they can't arrive too early because of the
weather. Once migrants do arrive, the short arctic
summer allows little time for laying eggs, hatching
them and teaching the young to fly before the
migration south in the fall. If geese also sought new
mates each year, they would never keep on
schedule Hence their permanent pairing enables
them to save time by performing many of their
prenesting rituals in southern latitudes.
