• Museum Eggs Help Solve Mysteries

  There are five million bird eggs stowed away in museums across the world — and the study of eggs, called oology, can give us great insight into birds. The link between DDT and the decline of Peregrine Falcon populations was identified in part using museum and personal egg collections, and this evidence helped lead to a ban on DDT. And today, Peregrines can still be seen zipping across the sky.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

• Kiwikiu

  Kiwikiu, also known as Maui Parrotbill, used to be found all over Maui and Molokaʻi. Now, fewer than 150 individuals exist and kiwikiu are currently restricted to a tiny region of high elevation forest on the slopes of Haleakalā. A translocation effort to expand their range was unsuccessful due to the rapid spread of mosquito-borne avian malaria.More info and transcript at BirdNote.org.Want more BirdNote?

• Altitudinal Migration

  Yellow-eyed Juncos sometimes make a migration of sorts — not from north to south, but from the high mountains to the lowlands or the other way around. It’s called altitudinal migration. In the warm summer months, some Yellow-eyed Juncos prefer to nest at higher elevations. In winter, however, the scarcity of food pushes them back down to the valleys.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

• How Art Inspired a Young Birder

  Isaiah Scott was in middle school when his family took him to visit the Cornell Lab of Ornithology. He remembers seeing a huge mural showing hundreds of colorful birds spread across a map of the world. That painting, called the Wall of Birds by Jane Kim, got Isaiah curious about how many of those species he might see for himself. In this episode, Isaiah shares how the artwork sparked his love of birding.There’s more to our conversation with Isaiah Scott in season 4 of Bring Birds Back!More info and transcript at BirdNote.org.Want more BirdNote?

• A Song That Has Survived for Thousands of Years

  Sometimes, a species’ song changes over the course of a few decades. But a bird that lives in the mountains of eastern Africa, the Forest Double-collared Sunbird, appears to have kept the same song for at least 500,000 years. That’s the amount of time that two populations of the species split up into two separate mountain ranges. Despite a lack of contact between those populations, they sing a nearly identical song, suggesting that it’s very similar to the one their ancestors sang long ago.More info and transcript at BirdNote.org.Want more BirdNote?
