It’s high season for moose on Maine highways. The Maine departments of Inland Fisheries and Wildlife and Transportation are asking drivers to take extra precautions in May and June. May and June are the most common months for moose collisions due to a combination of factors, including calving time, weather and salt. After a winter of eating browse, moose tend to travel more when the weather warms up and greens and other food sources become available to them again. Sodium is also an important part of a moose’s diet, so moose are drawn to roadsides where they can find salt run-offs. Nearly 90 percent of vehicle-moose collisions occur between dusk and dawn, when moose move around more and when it is especially hard to see their dark coloring.
