This is Episode 122. Host Ivan Phillipsen takes listeners into the vast sagebrush steppe of western North America and introduces the remarkable birds that call it home—the sage grouse. These birds are icons of the American West, tightly bound to a rugged ecosystem that covers nearly a third of the lower 48 states.

Ivan explores how sage grouse have evolved to thrive on a diet of sagebrush—plants laced with bitter, toxic chemicals that most animals avoid. From their unusual digestive adaptations to their elaborate courtship displays, these birds reveal fascinating strategies for survival in a tough landscape.

Listeners will learn about the two species of sage grouse, their distinctive appearances and behaviors, and the conservation challenges they face today.

This is Episode 121. In this unscripted “From the Field” episode, host Ivan Phillipsen takes listeners on an immersive, unscripted journey through his recent month-long travels in Japan. Splitting his time between scouting for a future birding tour and exploring for fun, Ivan revisits the country for the first time since spending a formative summer there as an 11-year-old.

He reflects on Japan’s geography, climate, and rich biogeographic history, from its tectonic origins to its unique mix of endemic species, setting the stage for the birding adventures that unfold.

Ivan’s travels span Tokyo’s green spaces, the slopes of Mount Fuji, the rice paddies and alps of central Honshu, and the wild northern landscapes of Hokkaido. Along the way, he shares encounters with both common and rare birds—species like Japanese Pygmy Woodpecker, Japanese Grosbeak, Masked Bunting, Narcissus Flycatcher, and the iconic Red-crowned Crane.
