Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 637 558 742

Probable 33 26 42

Possible 48 49 73

Species Total 718 633 857

Total in Atlas 1132 1041 3854

Species Percentage 63.43 60.81 22.24

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). Breeding codes of PE (Physiological Evidence), DD (Distraction Display), and UN (Used Nest) are not listed.

Max Abundance # Total Blocks
