“…Several earlier studies have reported a similar negative relationship (Cowie et al 1981;James & Verbeek 1985;Clarkson et al 1986;Jansen et al 2004). Jansen et al (2004) argued that cache density in caviomorph rodents is simply a by-product of dispersal distance; nondirectionally carrying seeds away from the food source automatically lowers cache densities.…”

“…This finding is in agreement with Clarkson et al (1986), who, based on OCST, predicted that the first seeds should be cached closer to the food source and the subsequent seeds both near and far, but the correlation in our study was much lower (R 2 ¼ 0.16) than in Clarkson et al (R 2 ¼ 0.60). With the exception of Clarkson et al (1986), no other studies that considered successive cache distances have found support for this prediction (Stapanian & Smith 1978;Cowie et al 1981;Vander Wall 1995). Thus, removal sequence seems a poor predictor of cache distance in general.…”

“…The results therefore should be interpreted with slight caution. Cowie et al (1981) placed control caches 10 and 100 cm away from real caches made in the field by marsh tits. They found that the real caches usually disappeared before the 10 cm control cache, that the overall disappearance rate of real caches was significantly higher than for the 100 cm controls and almost significantly higher than the 10 cm controls.…”

Understanding the survival value of behaviour does not tell us how the mechanisms that control this behaviour work. Nevertheless, understanding survival value can guide the study of these mechanisms. In this paper, we apply this principle to understanding the cognitive mechanisms that support cache retrieval in scatter-hoarding animals. We believe it is too simplistic to predict that all scatter-hoarding animals will outperform non-hoarding animals on all tests of spatial memory. Instead, we argue that we should look at the detailed ecology and natural history of each species. This understanding of natural history then allows us to make predictions about which aspects of spatial memory should be better in which species. We use the natural hoarding behaviour of the three best-studied groups of scatter-hoarding animals to make predictions about three aspects of their spatial memory: duration, capacity and spatial resolution, and we test these predictions against the existing literature. Having laid out how ecology and natural history can be used to predict detailed cognitive abilities, we then suggest using this approach to guide the study of the neural basis of these abilities. We believe that this complementary approach will reveal aspects of memory processing that would otherwise be difficult to discover.

“…Tomback's estimated probabilities were quite high, much higher than could be expected by chance. In another field study, Cowie et al (1981) placed mildly radioactive seeds in a feeder, and they were taken and cached by marsh tits and a scintillation counter used to locate cached seeds in the area around the feeder. A control seed was then placed 100 cm from each cached seed and survivorship of the seeds monitored.…”

“…Many corvids cache in the fall and then depend on their cached food throughout winter into the spring (Vander Wall, 1990). In contrast, within the parids many species cache for shorter periods of time, caching and recovering throughout the winter (e.g., marsh tits, P. palustris; Cowie et al, 1981), although there are some parids that cache in fall and use those caches for some months (e.g., crested tits, P. cristatus; Haftorn, 1954). Brodin (2005) has suggested that corvids possess a site-specific, accurate long-term memory, whereas parids may use a more general memory along with area-restricted search.…”
