Abstract
Uncertainty analyses of sequences of actions by wild Dissosteira Carolina gave average uncertainties (Ĥ) of 2.4 male and 1.9 female bits/act in all contexts. Noninteracting males show low diversity and insignificant between-act predictability (log-likelihood approximation). Males interacting with males or females had higher uncertainties and significant between-act predictabilities. In male–male interactions, approaching and responding animals were nearly equivalent and Ĥ(I) was 2.02 bits/act for both. Three-way analysis showed that the effect of an animal's last act was slightly lower than that of the other animal's last act with some overlap. Bidirectional-communication and character analyses were also performed. Male–male interactions are neither stationary nor Markov processes. In male–female interactions, males had much higher uncertainties than females (2.25 versus 0.83 bits/act) and interanimal information transmission was very low.
