Association of Zoos and Aquariums has declared February 29th Leap Day, the initial day of the Year of the Frog (and their amphibian cousins).
It is a part of a global conservation effort. The Association has all kinds of information and activities available at their site. The Ark even has some informational videos that could be used as conversation starters or discusion points?
Miss Rumphius Effect (one of my favorite book review bloggers!) has put together a fabulous group of frog- related resources in two separate posts to help all of us with this fun celebration.
