Treatment of the received dataset
We imported the
with modifications as follows to better combine with other atlases or to match publication cited above:
We included data on two hybrids (Brewster's Warbler, confirmed, and Lawrence's Warbler, possible) recorded by the atlas that were not mapped in the published atlas.
We also decided to map species not mapped in the published atlas that were reported as PR or PO: Chuck-will's-widow, Yellow-bellied Flycatcher, Common Raven, Tennessee Warbler, and Cerulean Warbler.
Second atlas: Massachusetts 2007-2011 (published!)
