The dinosaurs were headed for trouble. They ate nothing but junk food. They never brushed their teeth. They stayed up all night, and they jumped off cliffs even though they could not fly. To avoid extinction, they evolved into birds.

Their waddle has made them famous. These flightless marine birds have adapted well to the ice, snow, and frigid waters. Emperor penguins are the largest of all penguins, and they have several adaptations, which help them survive in cold environments.
In Hawaii, biological detectives study the honeycreeper, a bird once on the edge of extinction, now making a surprising comeback despite habitat destruction and non-native mosquito borne-disease. Is rapid evolution the answer? Segment of video from Wild Chronicles Series.
When Genoveva opens her magic book, the screen is filled with feathers, beaks, horns, legs, wings, and snouts. Genoveva's magic book transports her to various habitats where she learns about the animals that live there. In this episode, Genoveva learns more about the condors. Condors are one of the biggest and most mysterious species of big flying birds. They can weigh up to 26 pounds and measure 4.2 feet, and they can still fly really high.
Brooke Pennypacker discusses the importance of the whooping crane pen at the St. Marks National Wildlife Refuge. The refuge is home to a special project called Operation Migration. The program helps ensure cranes are strong enough to make their migratory journeys. Part of the "EcoAdventures in North Florida" series.
Explains how raptors (birds of prey) fly and hunt, comparing their abilities to those of high-tech fighter aircraft. The peregrine falcon, for example, surpasses even the F-22 Raptor aircraft in its speed, agility, and accuracy on target. Also studies eagles, kestrels, owls, vultures, falcons, and hawks. Focuses on the tactics of raptors hunts from hawks, taking advantage of bats' nighttime flights to hawks' teamwork in capturing their prey.
Why do some birds, like raptors, move from one region to another at certain times of the year? It is all about their interactions with the environment. The primary factor is scarcity in a food source. Another factor includes changes in the weather. This episode explains the seasonal events that affect the raptor’s migration and provides a platform to investigate the types of relationships found in their ecosystem. Part of the "Seasonal Science" series.
Over the past four decades, evolutionary biologists Rosemary and Peter Grant have documented the evolution of the famous Galápagos finches. They track changes in body traits directly tied to survival, such as beak length, and identify behavioral characteristics that prevent different species from breeding with one another. Their pioneering studies have revealed clues as to how 13 distinct finch species arose from a single ancestral population that migrated from the mainland 2 million to 3 million years ago.
For nearly 40 years, Dr. Ellen Ketterson and her research team from Indiana University have been studying juncos in the mountain forests of Virginia. This segment introduces viewers to the junco, the researchers, and the core methods they use to study birds. Set in field, lab, and aviary locations, one landmark study is highlighted in detail: a long-term field experiment investigating the complex effects of the hormone testosterone on behavior, physiology, and evolutionary fitness. Part of Ordinary Extraordinary Junco (Chapter 2).
The world’s largest scientific archive of animal signal recordings is housed at the Macaulay Library. The library is partnering with other institutions to curate and digitize an enormous archive of animal audio and video recordings from their vaults. The analogue material in the library’s collection includes recordings of birds, frogs, fish, and insects going back a few decades. Accessible digital audio recordings of these animal signals will make it easier for researchers to investigate a host of scientific questions. Part of the "Science Nation" series.
Scientist William Rowan is renowned for his research on the dark-eyed junco. Before Rowan, it was unknown what environmental cues animals used to time the seasonal changes in their biology. Through a groundbreaking experiment with the junco, Rowan discovered the physiological reaction of organisms to the length of day or night. Shot as an historical re-enactment, this segment provides a glimpse into the history and human dimensions of scientific research and reveals one of the first studies that made juncos well-known to biologists. Part of Ordinary Extraordinary Junco (Chapter 1).
Throughout North America, the species known as the dark-eyed junco exhibits striking differences in feather color, body size, and behavior from place to place. These variations among subspecies have caught the attention of biologists interested in diversification, evolution, and speciation. This segment features footage from junco habitats across the continent as researchers try to decode the riddle of the Junco’s evolutionary history. Part of Ordinary Extraordinary Junco (Chapter 3).
Part of "Show Me Science" series. Are animals intelligent? Bees communicate with each other. Monkeys use rocks and sticks to help them get food. Is this instinctual or is it evidence of thought? Some scientists believe that one measure of intelligence is self-awareness, and that an animal's reaction to its own image in a mirror can tell us whether or not it is self-aware. Looks at fish, birds, monkeys, and primates and their reactions to themselves in a mirror. Researchers look for signs of self-recognition as they observe, record, and interpret the reactions of these animals. Includes suggestions for careers in this field of study.
Most pet owners talk to their animals at one time or another, and some do every day. But, how much do pets actually understand? Is their perception anything like our own? These are the questions that fascinate Irene Pepperberg and she’s looking for answers from the animals themselves, specifically – African Grey Parrots. The Harvard psychology professor is a bit like the character Dr. Doolittle because she’s been talking to parrots for decades. With help from the National Science Foundation, she’s researching how much the birds understand about shapes, numbers, and colors. Her next phase of research involves how the parrots detect optical illusions, and whether they perceive them the way humans do. Her research will also reveal more about how a bird’s vision works.
Penguins are smallish, waddling birds. However, scientists have discovered that they evolved from a giant, flying ancestor millions of years ago. Part of the "Eons" series.
Describes the characteristics of river biomes and their diverse plant and animal life. Notes effects of their passage through varied geography and climates. Human impact on rivers remains both beneficial and harmful.
Marli Lintner, an avian veterinarian, shares her expertise on choosing a pet bird, common species, bringing a bird home, proper housing, nutrition and diet, health matters, trimming wings and nails, and taming a bird.
In this episode, host Jeff Corwin explores the largest wetland habitat in Botswana featuring a great herd of elephants, deadly hippos, snakes in trees, and exotic birds. Part of the "Ocean Mysteries" series.
Students will explore the energy relationships between living things. This video investigates the process of living things producing energy, consuming it, and breaking it down. Food chains and food webs visually illustrate these relationships.
Documentary records Project Puffin, the successful effort to repopulate Seal Island, Maine, with Atlantic puffins and terns. Notes their life, behaviors, and mating during the summer before fall migration. Also remarks on the interdependence of terns and puffins. Biologists comment.
