Sociable Weaver: 90 Days From Egg To Survivor | 100 Nests In One Tree

A hundred families live inside the same nest. When a snake gets in, it works through them one chamber at a time. Sociable Weavers build the largest bird nest on Earth: a mass of grass weighing up to a tonne, hanging from a single camelthorn tree in the Kalahari. Inside it are more than a hundred separate chambers, each with its own tunnel, its own pair, its own eggs. Some of these nests have been occupied for a century. It is the safest structure in the desert. It is also a single point of failure. A Cape cobra that gets inside does not have to find a nest. It has found all of them. And every year the straw grows heavier, until the branch that holds it cannot. This is 90 days inside that tree. The snake in the tunnels. The falcon that lives in the walls and takes what it wants. The heat. And the storm that brings the whole thing down. No narration. No music. Just the story. ────────────────────────────── 00:00 Day 1 00:56 Day 4 01:31 Day 8 02:06 Day 12 03:13 Day 16 03:48 Day 22 04:23 Day 28 05:38 Day 34 06:29 Day 40 07:04 Day 46 07:47 Day 52 08:54 Day 58 09:29 Day 64 09:56 Day 70 10:31 Day 76 11:06 Day 82 11:49 Day 90 ────────────────────────────── HOLLOW follows a single life from the first egg to the first flight.
