Crèche

The Crèche (from French) in zoology refers to care of another's offspring, for instance in a colony. This term is used in the study of bird colonies. Many penguins orm crèches, in addition to many other birds such as the Canada goose and common Eider
Among the reptiles, Spectacled Caiman also raise their young in crèches, one female taking care of her own as well as several others' offspring.
The word 'pop-up' brings to mind Czechoslovakian master Voitech Kubasta's imaginative creations. The eyes are startled by the three-dimensional scene that springs to life once one of his design covers is opened. The marvelous example at left only hints at the glory of pop-ups—before Kubasta, and since.
Perforated (or scored) for easy punching-out and assembly, puch-out crèches often take the form of stapled booklets. The punch-out "Manger Scene" shown at left—a Whitman 1963 classic edition—was my first introduction to the world of paper crèches. Bought for 29 cents at our local Kresge's, it has lost none of its power of wonder and amazement over all these years.
