| Abstract |
Sweet potato washing and wheat placer mining in Japanese macaques (Macaca fuscata) are among the most well known examples of local traditions in non-human animals. The functions of these behaviors and the mechanisms of acquisition and spread of these behaviors have been debated frequently. Prompted by animal caretaker reports that great apes [chimpanzees (Pan troglodytes), bonobos (Pan paniscus), gorillas (Gorilla gorilla), and orangutans (Pongo abelii)] at Leipzig Zoo occasionally wash their food, we conducted a study of food washing behaviors that consisted of two parts. In the first part we assessed the current distribution of the behavior on the basis of caretaker reports. In the second (experimental) part, we provided subjects individually with a water basin and two types of food (apples and cereal) that was either clean or covered/mixed with sand. We found that subjects of all species (except gorillas) placed apples in the water before consumption, and that they did so more often when the apples were dirty than when they were clean. Several chimpanzees and orangutans also engaged in behaviors resembling wheat placer mining. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 May 2014.
All research outputs
#20,577,582
of 25,286,324 outputs
Outputs from Primates
#942
of 1,067 outputs
Outputs of similar age
#151,445
of 199,256 outputs
Outputs of similar age from Primates
#9
of 9 outputs
Altmetric has tracked 25,286,324 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,067 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 19.6. This one is in the 3rd percentile – i.e., 3% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 199,256 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one.
