Les animaux en hiver

Qui Hiberne, Qui hiverne: une aventure animale au Quebec par Serge Gagnier (Joey Cornu, 2002, 127 pp). This is a gem oozing with enthusiasm. Strong efforts were made to involve kids in an understanding of winter life for animals. Kid-centered yet sophisticated. Lots of questions generated by kids including "Est-ce que l’ours va a la toilette pendant son hibernation?" Numerous activities suggested.
Hibernation par John Stidworthy et Stephane Passereau (Gamma, 1993, 32 pp). Each 2-page section is headed by a large-font summary, has about 4 images (photos, sketches, charts) with descriptions, and 1-3 subtopics with good use of topic-specific vocabulary. Note that the glossary is sparse while the text is rich.
Encyclopedia Decouverte benjamin. La vie des animaux en hiver, no 13 (Gallimard Larousse). A good place to start with some beautiful classic illustrations that sensitize to animal life under the trees, earth, and water.
