Black-and-white Warbler Map and Data

Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 244 217 272

Probable 237 225 316

Possible 71 59 155

Species Total 552 501 743

Total in Atlas 1132 1041 3854

Species Percentage 48.76 48.13 19.28

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.
