Question: There are large bird houses on the shores of the lake I fish. Are these wood duck houses, and do they really help the duck population? Answer: They are probably wood duck nesting boxes, and they are used by more than just wood ducks. Many ducks are cavity-nesting ducks like wood ducks, including buffleheads, barrow's goldeneyes, common goldeneyes, hooded mergansers and common mergansers, and all of which benefit from these man-made nesting boxes.

Question: Like a lot of hunters, we use game cameras to spot deer. We’ve seen some interesting animals, including bobcats and bears. With so many game cameras out there, does anyone want our pictures for scientific purposes? Answer: Yes, public agencies are interested in your photos. As you know, game cameras, also known as trail cameras, have come a long way. Decades ago, they used film that had to be processed to see the photos.

Question: Earlier this winter I found a frog in my garden that was frozen solid and appeared to be dead. I heard that some frogs can freeze without dying. Is that really true? Answer: Yes, it is, and the frog may survive the winter. Minnesota has 14 different types of frogs and toads, and four of these have the amazing ability to survive winter by letting most of their bodies freeze. These frogs are the wood frog, the spring peeper, the gray tree frog and the similar Copes gray tree frog.

Question: We had over 50 swans on our lake this fall, and we never saw them years ago. Why are there so many swans now? Answer: The swans you saw are most likely trumpeter swans, and their comeback is attributed to extensive efforts by several public agencies. Before European settlement of Minnesota, trumpeter swans lived across much of North America. Then, in the 18th and 19th centuries, hunters took swans for their skin, feathers and meat, and farming reduced swan habitat.
