Mikko Jimenez is a PhD student doing research on bird migration. Growing up in Chicago, he played beach volleyball at Montrose Beach, a popular spot on the lake shore. At the time, he wasn’t so aware of birds, but as he developed an interest in birding in college, he realized that his old…

Sandhill Crane families form a close bond. A pair of adults might travel north with their young from the previous summer, along with grown-up offspring from several years ago. After the breeding season, families will stick together for the journey south and the winter, even in large flocks…

When they migrate, tiny songbirds that spend most of their lives on land fly hundreds of miles over the ocean at a stretch – and they get tired. A recent study suggests that birds migrating over busy shipping routes in the Mediterranean Sea may use the decks of sea vessels as places to…

Throughout much of North America, the Great Blue Heron graces waterways, ponds and lakes. They’re built for hunting fish and amphibians along the water — so it might be a surprise to see one stalking across a field, not a drop of water in sight! But sometimes herons leave the water to…

Birds of the same species don’t always sing exactly the same as each other. But those that live near each other sometimes have similar songs. Scientists refer to this pattern as a song neighborhood. It’s less like a regional dialect among people that’s found over a large area. It’s more…

Bird feathers are famously light, but they’re also strong, holding up under tricky flying and high winds. They’re made of beta keratin, a tougher version of the keratin that makes up human fingernails and hair. They also have an intricate branching structure that makes them highly flexible…

Milkweed plants are important to Monarch butterflies, which depend on milkweed to raise their caterpillars. But Monarchs aren’t the only ones who benefit from milkweed. Scientists once documented hundreds of insect species they found eating some part of the common milkweed plant –…

In spring and summer, the paths around local ponds might have some fluffy obstacles: young goslings along with their caring and defensive parents. Adult Canada Geese lose their flight feathers for several weeks in the summer, often while they’re raising a brood of goslings. Without the…

A city lake is one of the most prized places in a fast, growing environment. It’s also often difficult to distinguish all of the bird calls from each other. With a splash of a beak, a glide of a wing, and an eye of a predator — listen closely, and then again to sharpen your bird ear…

This season has been all about the mutual impact birds, humans and nature have on each other. To close it out, Bill McKibben joins us for an honest chat about the future of this dynamic, which inevitably includes the planet Earth. His book debut, “The End of Nature,” first sounded the…
