Ruby-throated Hummingbird Map and Data

Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 258 177 299

Probable 375 362 493

Possible 252 280 372

Species Total 885 819 1164

Total in Atlas 1132 1041 3854

Species Percentage 78.18 78.67 30.20

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.
