Bird Names for Birds (BNFB) is a campaign to change the common names of American birds that were named after people (i.e., eponyms). Officially launched in June 2020 with a public petition, the BNFB movement emerged after several years of social activism by multiple American ornithologists and birders, many of whom are not affiliated with BNFB but remain devoted to the cause. BNFB was formally launched with a public petition dated June 22, 2020, co-signed by 182 individuals, which urged the American Ornithological Society (AOS) to "acknowledge the issue of eponymous and honorific common names, to outline a plan to change harmful common names, and to prioritize the implementation of this plan."
