Purple Martin Map and Data

Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 245 175 301

Probable 19 18 29

Possible 38 33 56

Species Total 302 226 386

Total in Atlas 1132 1041 3854

Species Percentage 26.68 21.71 10.02

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.
