| Abstract |
There is increasing evidence that animals can learn abstract spatial relationships, and successfully transfer this knowledge to novel situations. In this study, rufous hummingbirds (Selasphorus rufus) were trained to feed from either the lower or the higher of two flowers. When presented with a test pair of flowers, one of which was at a novel height, they chose the flower in the appropriate spatial position rather than the flower at the correct height. This response may also have been influenced by a preference for taller flowers as acquisition of the task during experimental training occurred more readily when the reward flower was the taller of the pair. Thus, it appears that although learning abstract relationships may be a general phenomenon across contexts, and perhaps across species, the ease with which they are learned and the context in which they are subsequently used may not be the same. |

| Abstract |
It is believed that environmental enrichment techniques can play an important part in creating suitable captive environments for horses. There has, however, been little scientific investigation into the effectiveness of 'stable-toys' which claim to reduce the performance of equine stereotypies. This study investigated the effect of a foraging device known as 'The Equiball' on equine stereotypies. Six horses were given their evening feed in an Equiball, and the occurence of stereotypic behaviour recorded using scan sampling of video observations. Pre-enrichment, horses spent a mean(SD) of 5.27 ? 8.17 per cent of their time in the stable performing stereotypies; and significant individual variation in mean time performing stereotypic behaviour was found (P < 0.05). Several peaks in stereotypy over the day were found, the two main ones corresponding to the times before feeding. A reduction in stereotypic behaviour in five horses, and a small increase in stereotypic behaviour in one horse was observed during enrichment. During enrichment, there was an overall trend for stereotypic behaviour to decrease (P < 0.1). When used in conjunction with other measures such as behaviour therapy, companionship, increased exercise, and so on, the Equiball may help to create an environment less likely to lead to the development of stereotypic behaviours. |
