 Species Total is the sum of all quads/priority blocks/total blocks the species was recorded in with at least a Possible breeding status. Total in Atlas is the number of quads/priority blocks/total blocks in the atlas with data (regardless of species). Species Percentage is the Species Total quads/priority blocks/total blocks divided by the Total in Atlas quads/priority blocks/total blocks.

 Territorial/Courtship category includes five Probable breeding codes: T (Territorial), C (Courtship), N (Hole Nesters Visiting Nest Site), A (Agitated Behavior or Anxiety Calls), and B (Nest Building by wrens or woodpeckers). Nest Building category includes CN (Carrying Nesting Material) and NB (Nest Building). Nest with Young category includes NY (Nest with Young) and FS (Carrying Fecal Sac).
