Outcomes of all begging bouts between potential donors and beggars by year and potential donor.

Outcomes are scored as a “share” “no share” (refusal to share) or “steal” as described in text. Cacao and Fantasma were the breeding female and male during 2004–2006, while all others are their offspring. Year of birth given where known. Animals to the right of the unknown (“unk”) donor column are juveniles who dispersed before the 2006 field season. Observations are based on 86, 45, and 34 contact hours in 2004, 2005, and 2006, respectively.
