Animals, like humans, need a place they can call home to provide a safe and stable place to raise a family, but they go about building it in entirely different ways. Whether it is a bird’s nest, bear den, beaver lodge or spider web, these are homes of great complexity, constructed from a wide range of natural as well as man-made materials.

This three-part series investigates just how animals build their remarkable homes around the globe and the intriguing behaviors and social interactions that take place in and around them. Hosting the series is ecologist Chris Morgan ("Siberian Tiger Quest," BEARS OF THE LAST FRONTIER), who serves as guide and real estate agent. He evaluates and deconstructs animal abodes, their materials, location, neighborhood and aesthetics. In addition to Morgan opening the doors of animal homes in the wild, he is also in studio showing examples of the incredible diversity of nests and their strength, even trying his hand at building a few. ANIMAL HOMES premiered on three consecutive Wednesdays, April 8, 15 and 22, 2015.

The series features a blend of CGI, animation, CT scans and signature blueprint graphics to highlight engineering principles inside the structures. A variety of cameras, including tiny HD versions, capture unprecedented views inside animal homes without disturbing natural behavior. When appropriate, filmmakers shoot behaviors in slow motion and use infrared and time lapse to reveal how animals create their structures over time and through the seasons. Over the course of three episodes, the series delves into the amazing flexibility animal architects display, the clever choices they make and the ingenious ways they deal with troublesome habitats.

"The Nest" aired Wednesday, April 8, 2015 at 8 p.m. - Bird nests come in all shapes and sizes, crafted from a diversity of materials, including fur, grasses, leaves, mosses, sticks and twigs, bones, wool, mud and spider silk. Quite a few contain man-made materials — twine, bits of wire, even plastic bags. Each is a work of art, built with just a beak! All over the world, birds in the wild arrive at diverse nesting grounds to collect, compete for, reject, steal and begin to build with carefully selected materials, crafting homes for the task of protecting their eggs and raising their young.

"Location, Location, Location" aired Wednesday, August 12, 2015 at 8 p.m. - Finding a good base of operations is key to successfully raising a family. One must find the correct stream or tree, the correct building materials, neighbors and sometimes tenants. In the wild, every home is a unique DIY project, every head of household is a designer and engineer. Animated blueprints and tiny cameras chart the building plans and progress of beavers, saltmarsh sparrows, woodrats, gray jays, hawks and black-chinned hummingbirds examining layouts and cross sections, evaluating the technical specs of their structures and documenting their problem-solving skills. Animal architecture provides remarkable insights into animal consciousness, creativity and innovation.

"Animal Cities" airs Wednesday, August 19, 2015 at 8 p.m. - Animals congregate in huge colonies partly out of necessity and partly for the security that numbers provide. Puffins in the Hebrides, off the west coast of Scotland, form nesting colonies of more than a million, tucked in between hundreds of thousands of other seabirds, which provides shared information about food sources and reduces the odds of individual birds being attacked. But, colonies are also useful for predators. Social spiders in Ecuador work together to capture prey 20 times the size an individual might subdue on its own. For others, communal living provides perfect multi-generational caregiving options or the opportunity to build enormous cities – such as the acre-wide, multi-million-citizen colonies built by leaf-cutter ants in Costa Rica.
