Flashback Friday (since we’re a day late for Throwback Thursday): Professor Homer Dill, museum taxidermist and professor of zoology, on a specimen-gathering expedition in Washington, 1920. The back of the photo reads: “Professor Dill looks closely at some small mammals when he might have been looking at the scenery.” In 1926, Dill would succeed Charles Nutting as the museum director.

#WildWednesday : the thirteen-lined ground squirrel (Spermophilus tridecemlineatus) maintains its distinct fur pattern even as an an albino. In 1949, researchers found that the hairs in the stripes of the albino squirrels were 23 percent longer than the other hairs on the squirrel, which may cause the pattern to occur.

#ThrowbackThursday: Stewart MacDonald with golden eagle mount, 1958. After working for several years as a zoology technician at the National Museum in Ottawa, Canada, before pursuing museum studies here. Stu returned to the National Museum as the assistant curator of birds and went on to a prolific career as a museum professional, arctic scholar, ornithologist and conservationist. The Royal Canadian Geographical Society honored his career with the prestigious Massey Medal in 1992.

#WildWednesday: Last week marked the 100th anniversary of the passenger pigeon’s extinction. These birds, which were once so abundant they would blacken the sky as they flew overhead were driven to extinction by commercial hunting. Fourteen years before the last passenger pigeon died in 1914, Congressman John F. Lacey of Iowa introduced the first wildlife protection act, because of the the bird’s decline.

Two-toed Sloth
Albert Seba’s (1665-1736) four volume Thesaurus (Locupletissimi rerum naturalium thesauri accurata descriptio…) illustrated the Dutch apothecary’s enormous collection of animal and plant specimens amassed over the years. Using preserved specimens, Seba’s artists could depict anatomy accurately—but not behavior. For example, this two-toed sloth is shown climbing upright, even though in nature, sloths hang upside down.
See this and other illustrations from the Museum’s Rare Book Collection in Natural Histories: 400 Years of Scientific Illustration from the Museum’s Library.

Sloths are our favorite :)

The striped skunk (Mephitis mephitis) has a special gland beneath its large tail that sprays a foul-smelling oil to defend against predators. The skunk can blast this spray up to 12 feet to protect itself.

#WildWednesday: Wild turkeys largely disappeared from Iowa by 1900, due to habitat loss and overhunting. In 1965, 11 turkeys from Missouri were released here. The flock flourished, and other releases were made. Today, turkey densities are higher than ever in some places, as the birds have adapted to smaller habitats and feeding on waste grain in winter.
