The overlap of Male no. 45's territory is pictured with the home ranges of six adult females observed at least once in his territory, for each of which there were at least five sightings. The mean number of sightings per female was was seen was nearly a month earlier, 43 m away, at which time he was seen cop- ulating. In summary, it is clear that adult males overlap with each other tremendously, both in space occupied (Fig. 8) and in access to members of the opposite sex (Figs. 5, 7). Commonly several males copulate with the same female and several males copulate with different females in the same space. Fights are short, mild and lead to withdrawal and hiding. Some males, at least, are highly variable in their movements, during some periods moving considerable dis- tances, during others remaining mostly in one place (Fig. 6). Male-male compe- tition must take an interesting and com- plex form in A. valencienni that would repay careful study. FEMALE AGGRESSIVENESS IN A SEARCHING SPECIES Why are female valencienni not ag- gressive? Imagine the contrary. Imagine that each female defends a territory with- in which to feed. Assume a female com- pletes the search of her territory for food.
