La Sorte, Travis Moore, Andrea Wiggins, Weng-Keen Wong, Chris Wood, Jun YuBCRs are ecologically distinct regions with similar bird communities. BCRs were used to cluster checklists into groups with similar likelihoods of species encounter. Data from six BCRs were used in this study: BCR 9- Great Basin, BCR 23- Prairie Hardwood Transition, BCR 30- New England/Mid-Atlantic Coast, BCR 31- Peninsular Florida, BCR 32- Coastal California, and BCR 37- Gulf Coastal Prairie. These BCRs were selected to include a range of eBird participation (Table 1) and varying degrees of diversity and patterns of bird occurrence.
