A bird's nest can be woven, stacked, molded or stitched from surprisingly ordinary materials. Explore the movements, material choices and structural tradeoffs that help nests hold together. Inside this episode: - There is no single bird nest - The foundation - Friction and entanglement - Weaving, knotting, and tucking - Mud, silk, and other binders Sources include Current Biology, Nests and nest building in birds, Avian Biology Research, design and function of birds' nests, and Construction patterns of birds' nests. This episode is a researched narrative summary. Historical records may be incomplete, translated differently, or interpreted differently by scholars. We distinguish documented facts, estimates, disputed interpretations, and later stories where material. Corrections are logged and incorporated into future editions.

See how thousands of starlings produce a coordinated murmuration without a single bird directing the flock. Local responses, visual cues and predator pressure help explain the moving patterns overhead. Inside this episode: - Before the roost - The predator in the sky - No leader at the front - Who counts as a neighbor - The dark waves Sources include PLOS One, citizen science and starling murmurations, Behavioral Ecology and Sociobiology, collective escape, and Empirical study of naturally occurring starling flocks.

Follow the hearing experiments that reveal how some owls locate hidden prey with remarkable precision. Ear placement, facial feathers and split-second timing all contribute to the hunt. Inside this episode: - A target made of sound - Left, right, early, late - Finding height - The facial disc - Why the head moves Sources include Journal of Experimental Biology, Acoustic Location of Prey by Barn Owls, How the Owl Tracks Its Prey, review, and U.S. Department of the Interior, owl adaptations.
