Phenology Table

The table displays data on breeding phenology (the timing of breeding behaviors) for 196 individual bird species. The behaviors are categorized by standardized breeding codes (see Atlas Methods) associated with breeding confirmations (e.g., nests and fledged young). Also included is nest building by cavity nesters (code indicated by “B”), which is a breeding code reserved for species that build dummy nests or cavity nests like woodpeckers, wrens, chickadees, and titmouse; this code is associated with probable breeding.

The table displays the first and last dates, as well as the median date, for each behavior/code. The table is based entirely on data collected during the Second Atlas and aggregates all the data displayed in the phenology charts of the individual Species Accounts.
