The 2016 calendar cover features a beautiful magnolia warbler. This year's theme is habitats for birds with bird-specific phenology data from the Wisconsin Breeding Bird Atlas.


Phenology is the study of periodic plant and animal life cycle events in nature that are influenced by climate and seasonal change, such as wildlife emerging from hibernation, birds nesting or migrating, and flowers blooming.  


Aldo Leopold recorded phenological events in Sauk County, Wisconsin, beginning in 1936 and later translated some of these observations into his famous book, A Sand County Almanac. The dates in this calendar are based on Leopold's data, data gathered more recently by his daughter, Nina Leopold Bradley, and data collected by other natural resource professionals.


Past calendars are available online.
