Reference	Rosenberg KV et al., Decline of the North American avifauna, Science 19 Sep 2019: eaaw1313 DOI: 10.1126/science.aaw1313 Supplementary Materials table S2
Method	Abstract: "Using multiple and independent monitoring networks, [investigators] report population losses across much of the North American avifauna over 48 years, including once common species and from most biomes." See note above table. See ref (100) beneath table
Comments	P.2 left column 3rd paragraph: "More than 90% of the total cumulative loss can be attributed to 12 bird families (Fig. 3A), including sparrows, warblers, blackbirds, and finches. Of 67 bird families surveyed, 38 showed a net loss in total abundance, whereas 29 showed gains (Fig. 3B), indicating recent changes in avifaunal composition (table S2)."
