Behavioural time-energy budgets of cooperatively breeding Neolamprologus pulcher
Article Abstract:
The metabolic rates associated with specific social and territory maintenance behaviors of the cooperatively breeding cichlid Neolamprologus pulcher were measured using a respirometer to examine the energy expenditures resulting from the helping behavior of the specie. Pair males were found to invest almost exclusively in intrafamily agonistic behavior, while pair females and helpers shared investment in brood care and territory maintenance. The behavioral energy expenditure of helpers was found to be strongly influenced by their submissive behavior.

Yelling for sex: harem males compete for female access in bronze-winged jacanas
Article Abstract:
Females may mate with several males, leading to sperm competition, and this is the case for sex-role reversed bronze-winged jacanas. Females may hold territories with as many as four males, copulating with all of them. Males may seek to attract females through a type of call known as a 'yell'. Males yelling loudest appear to be preferred by females. Yells may be attractive to female intruders, and female may respond to a yell from their mate for this reason.

For whom does the hen cackle? The function of postoviposition cackling
Article Abstract:
Research describing the function of postoviposition cackling in feral fowl is presented. It is suggested that the period after oviposition is unfavorable for insemination and therefore cackling may be directed as a warning to males.
