| Abstract |
The aim of this study was to provide basic data on ant-fishing behavior among the M group chimpanzees at the Mahale Mountains National Park, Tanzania. Ant-fishing is a type of tool-using behavior that has been exhibited by Mahale chimpanzees when feeding upon arboreal carpenter ants (Camponotus spp.) since the 1970s, and is now regarded as a candidate of wild chimpanzee culture. Herein, I describe in detail the features of ant-fishing shown by the Mahale M group chimpanzees: (1) 2 species of Camponotus ants (Camponotus sp. (chrysurus-complex) [C. sp.1] and C. brutus) were identified as the target species of ant-fishing, and C. sp.1 was selected intensively as the main target; (2) 24 species (92 individuals) of trees were identified as ant-fishing sites-these were widely distributed throughout the western/lowland region of the M group's home range, and the top 5 species were used more frequently; (3) the efficiency of ant-fishing was influenced not only by the site choice or the skillfulness of the chimpanzees, but inevitably by the condition of the ants; (4) the estimated nutritional intake from ant-fishing was apparently negligible; (5) most of the M group members (50/60 individuals) older than 3 years of age successfully used tools to fish for ants; and (6) female chimpanzees engaged in ant-fishing more frequently and for longer periods than males did. Further, I compared the features of ant-fishing exhibited by the Mahale M group chimpanzees with those exhibited by the former K group at Mahale and by other populations of wild chimpanzees. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 01 March 2012.
All research outputs
#14,077,403
of 22,663,150 outputs
Outputs from Primates
#781
of 1,013 outputs
Outputs of similar age
#82,104
of 124,321 outputs
Outputs of similar age from Primates
#5
of 7 outputs
Altmetric has tracked 22,663,150 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,013 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 17.3. This one is in the 22nd percentile – i.e., 22% 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 124,321 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 33rd percentile – i.e., 33% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 7 others from the same source and published within six weeks on either side of this one. This one has scored higher than 2 of them.
