House Wren Map and Data

Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 759 700 1048

Probable 152 165 266

Possible 59 55 120

Species Total 970 920 1434

Total in Atlas 1132 1041 3854

Species Percentage 85.69 88.38 37.21

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.
