Farmers’ Almanacs have been around for hundreds of years, offering detailed advice about things like the best time to plant certain crops, and when to wean your calves. But do farmers actually use them? Host Flora Lichtman discusses their place in modern life with astronomer and Farmers’ Almanac contributor Dean Regas, and Missouri farmer Liz Graznak.

Plus, zebra finches build their nests with a keen eye for color. But is their style easily swayed by feathered peer pressure? Zebra finch expert Lauren Guillette fills us in.

Plus, the latest on sea turtle nesting season, and an ancient sea turtle stampede.
