No blueprints. No tools. Just some of the most impressive construction projects on Earth.

Meet beavers that reshape entire rivers, weaverbirds that tie knots with their beaks, and termites that build towers taller than a grown-up. There are spiders with hidden trapdoors, insects that build portable homes out of pebbles, and a bird that decorates its courtship bower almost entirely in blue.

Sir Waddle, a naturalist with deep admiration for anyone who finishes a building project on time, guides young readers through thirty of the animal kingdom's greatest builders using real science, dry humor, and beautiful vintage natural history illustrations.

"The weaverbird finished its nest in under a week. I have been waiting on my kitchen for two years." —Sir Waddle

Inside you'll find:

• 30 animal architects, including the beaver, satin bowerbird, mound-building termite, and caddisfly

• Restored vintage illustrations on every spread

• Fun facts, Quick Facts, and conservation status for each animal

• Scientific names explained, with a wink

• Sir Waddle's handwritten field notes

• Hands-on "Try It!" building activities

A natural fit for STEM-minded kids ages 7–10, classroom science units, and young builders of all kinds.
