| Abstract |
Marsh tits (Parus palustris) store single food items in scattered locations and recover them hours or days later. Some properties of the spatial memory involved were analyzed in two laboratory experiments. In the first, marsh tits were offered 97 sites for storing 12 seeds. They recovered a median of 65% of them 2-3 hr later, making only two errors per seed while doing so. Over trials, they used some sites more often than others, but during recovery they were more likely to visit a site of any preference value if they had stored a seed there that day than if they had not. Recovery performance was much worse if the experimenters moved the seeds between storage and recovery. A fixed search strategy that had some of the same average properties as the tits' search behavior also did worse than the real birds. In Experiment 2, any tendency to visit the same sites on successive daily tests in the aviary was placed in opposition to memory for storage sites by allowing the tits to store more seeds 2 hr after storing a first batch. They tended to avoid individual storage sites holding seeds from the first batch. When the tits searched for all the seeds 2 hr later, they tended to recover more seeds from the second batch than from the first, i.e., there was a recency effect. |

| Abstract |
An understanding of patterns of leadership during grazing movements is important where the management of grazing cattle is concerned. This paper describes the leadership displayed by grazing cattle by recording the spatial relationship (grazing style) among herd members as the group progressed slowly through a field. Grazing style was divided into “A”, “B” and “C”, meaning following, independence and leading, respectively. The results revealed the following features: (1) the frequency distributions of grazing style and grazing formation used by the herd varied with the seasons; (2) the individual animal variation in grazing style did not fundamentally change with the seasons; (3) there was negative linear correlation between Styles A and C and between Styles A and B. The more any cow followed the grazing movement, the less likely it was to lead the grazing movement or to be independent. Styles C and B tended to be positively related; (4) high, medium and low ranking animals in social dominance showed tendencies to behave in Styles C, A and B, respectively; (5) grazing style and weight gain were not clearly related; (6) the cows that tended to lead, be independent or follow less, tended to get out of their paddocks. The observations suggested (1) that the leader-follower-independent relationship, although modified in each season, did not vary fundamentally, (2) that the active movement of high ranking animals and the independent movement of low ranking animals governed the voluntary formation in grazing, and (3) that as grazing cattle that behaved in a single group and did not escape from their paddock were much easier to manage, the grazing style that expressed these characteristics was one of the significant indices for management of grazing cattle. |

| Abstract |
When tested in circular open fields male and female mice (Mus musculus) produced strongly centrifugal urination patterns, which showed a clear `edge-dependency' in all the field sizes used. However, striking sex differences in the pattern of deposition were shown in terms of both the number and distribution of the urine spots. Male mice produce large numbers of spots which are regularly dispersed, while females produce relatively fewer spots with a more clumped distribution. It is suggested that a hitherto unsuspected level of intersexual communication may explain these differences. |
