The bird outside the window built that nest, laid those eggs, and is running a whole operation your kid has never seen inside of. Rachel Ignotofsky opens it up: what happens in the egg, how a chick hatches, how feathers work, how a nest actually gets built.

Ignotofsky made her name turning dense science into art people hang on walls, and this is that skill aimed at four to seven year olds. Forty eight oversized pages, warm and funny and genuinely accurate, from the creator of the bestselling Women in Science. It is the nature book that makes a kid look up.
