Peregrine Falcons Removed from IL Endangered List

Peregrine Falcons have their share of claims to fame—with a diving speed of over 200 miles per hour, they’re the fastest animals in the world, and they’ve adapted from living on rocky cliffs to a different kind of “mountain”: Chicago’s skyscrapers.  But in 1951, there were none left in Illinois, and it looked as if the species would be wiped out of North America entirely. Today, thanks largely to the Chicago Peregrine Program headed by The Field Museum’s Mary Hennen, Peregrines are flourishing to the point that they’re no longer in immediate danger.

New Discoveries in How Animal Moms-to-be Feed Their Babies

  Pop quiz—what kinds of animal mothers feed their babies before birth? The first (and maybe only) ones to come to mind are probably mammals like us—moms-to-be funnel nutrients from their blood supply right to their developing embryos through an organ called the placenta; the moms literally “eat for two.” That’s a different kind of nourishment than you see in most other animals—the majority lay eggs with a nutritious yolk for the embryo to use as it develops.

Field Museum Intern Hannah Ranft takes a stab at revising New Zealand lichens

Macrolichens in the family Lobariaceae are among the most conspicuous and charismatic lichens on the planet, due to their often large, colorful thalli and their ecological importance and potential uses. Many species have cyanobacterial photobionts and are capable of fixing atmospheric nitrogen, hence acting as biological fertilizers. Lobariaceae are also good indicators of environmental health and the conservation status of forest ecosystems. Species such as Lobaria pulmonaria have been used in homoeopathic medicine.
