Common Loon Map and Data

Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 162 99 228

Probable 34 40 59

Possible 30 26 93

Species Total 226 165 380

Total in Atlas 1132 1041 3854

Species Percentage 19.96 15.85 9.86

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.
