Many older cow moose give birth to twins. Moose populations dwindled in the early 1900's and in 1935 moose hunting became illegal. In 1980 hunting was reinstated in Maine. Today there is a one week legal moose hunting season, evidence that the moose population is sound in the State. It was believed that moose seek watery areas to get relief from bugs and the heat, but recent studies show that the moose is actually searching for sodium lost during the winter months.
Many aquatic plants are rich in sodium.
This craving of sodium is also why many moose are seen on roadsides during the spring. They enjoy licking the accumulated salt that was spread during the winter season. And you never know what a bull moose will do during mating season. When you're out driving logging roads, remember that many of these roads are owned by paper companies.
