Red-breasted Nuthatch Map and Data

Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 250 211 290

Probable 127 116 170

Possible 108 97 205

Species Total 485 424 665

Total in Atlas 1132 1041 3854

Species Percentage 42.84 40.73 17.25

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.
