Upgrade StorageStyle error: [Animal Behaviour]
The style for Animal Behaviour (Elsevier) incorrectly lists (in the in-text citations) all authors for sources with > 3 authors. Animal Behavior calls for "et al." for sources with ≥ 4 authors.

AB is just a dependent style of the apa.csl style.
As outlined in their guidelines that's what is specified, APA 6th edition.
In line with APA style, the style will print up to 5 authors the first time an item is cited, and then go to et al for 3 or more authors for any subsequent citation.
