(Aug 12, 2021) Pigeons and doves, both domestic and feral, are the same species. Today's urban environment mimics their original favored habitat, seaside cliffs in Europe and Asia.

(Aug 5, 2021) The Northern Flicker is one of the most recognizable birds. This distinctly-marked member of the woodpecker family, instead of browsing wood for their food like their relatives, digs for food in the ground. Martha Foley and Curt Stager explore its habits.

(Jul 29, 2021) Animals that resemble each other may not be closely related. Sometimes the setting shapes their bodies more than their ancestry. Manatees may look like whales or walruses, but that is only because they adapted to the marine environment in a similar way. Martha Foley and Curt stager talk about convergent evolution.

(Jul 22, 2021) The big marine herbivore, the manatee, is thought by some to be the origin of mermaid legends, but it's not closely related to humankind or even to whales and other marine mammals.

(Jul 15, 2021) Lake trout require a lot of cold, oxygenated water to survive. Lakes in the Adirondacks of upstate New York are at the southern edge of their natural range. Although about 100 Adirondack lakes and ponds are still home to lake trout, even a small increase in temperature could sharply cut that number.

(Jul 8, 2021) Researchers have found that variations in the wingspan of cliff swallows has a measurable impact on their survival in a human-dominated environment.
