"[1] Originally concentrated on finding, listing, and identifying rare birds, the ABA now seeks to serve all birders with a wide range of services and publications.

[2][3] On the suggestion of Stuart Keith, the next issue of Tucker's newsletter bore the name Birding (volume 1, number 1).

[3] Expressly excluding conservation advocacy and ornithological research, the ABA's initial focus was on the hobby and sport of birding.

[2] Through its publications and events, the early ABA sought to connect avid birders, establish rules for listing, and communicate the latest identification techniques.

[5] Subsequent presidents of the organization have included Arnold Small (1976-1979),[6] Joseph W. (Joe) Taylor (1979-1983),[7] Lawrence G. (Larry) Balch (1983-1989),[8] and Allan Keith (1989-1993; 1997–1999).

[9] In 1998, the ABA assumed responsibility for the publication of the National Audubon Society's journal Field Notes, subsequently renamed North American Birds.

The ABA is a partner in the ongoing publication of a series of photographic field guides to the birds of particular states (12 titles).

[27] In addition to offering ABA apparel,[28] the organization has partnered with for-profit companies to sell identification and bird-finding guides, binoculars, and items related to conservation.

[30] The IFO workshops, established to foster cooperation between professional and amateur ornithologists, blend classroom instruction and field study.

[13] The ABA presents several awards for promoting the cause of birding, advancing the state of ornithology, and making significant contributions to education and conservation.
