ASAB has close links with the Animal Behavior Society (ABS), a sister organization based in the USA.

ABS is a non-profit scientific society, founded to encourage and promote the study of animal behaviour. ABS members are from all over the world, but primarily from North, Central, and South America. Membership is open to those interested in the study of animal behaviour.

The society was founded in 1964 to promote the study of animal behaviour in the broadest sense, including studies using descriptive and experimental methods under natural and controlled conditions.

Current members' research activities span the invertebrates and vertebrates, both in the field and in the laboratory, and include experimental psychology, behavioural ecology, neuroscience, zoology, biology, applied ethology, and human ethology as well as many other specialized areas.
