The PIF Science Committee is also categorizing all North American landbirds into habitat categories. While this has been done for various bird groups in various ways over the years, this will be the first time bird experts in the three countries have produced an agreed-upon classification system.  As with the threats assessment, this classification will help identify sectors of the avifauna that share particular conservation issues.  As we have already seen, the outcomes are not always as conventional wisdom might have it.
