Do captive Capuchin's show signs of aggression
during feeding times
Introduction
Do captive Capuchins show signs of
aggression to one and other during feeding times. This study was to show whether
the two captive capuchins at Newquay Zoo, show signs of aggression to each
other during feeding times(Arkive, 2013). This study is aimed to find out what behaviours the
capuchins show during their feeding times and weather the more dominant male called
Tux shows signs of aggression to the less dominant male
The capuchins in Newquay Zoo are Yellow-breasted capuchins which
are a small types of monkey with a yellow chest and upper arms and have black
feet and hands as shown in fig1. these type of monkeys are endemic to brazil
The question is about the behaviour of the dominant male and how
his behaviour is affected during feeding times, this question is also to see
weather or not the dominant male shows signs of aggression to the other male.
Method used
We collected the data by going to the zoo at set times to record
the animals behaviours using a one zero ethogram which is where you record all
the behaviours that happen within a minute, for a fifteen minute period. we
took these fifteen minute over a week long period totaling 5hours of data. we
did these sorter recording times over several days to spread out the data. The
ethogram we used recorded several behaviours including passive behaviours,
feeding behaviours, submissive and aggressive behaviours (educationscotland, no date) We choose these
behaviours because it shows all types of behaviours and how the dominant
capuchin behaviours with the other male. The main aim of this method of study was to look for aggressive behaviours to see if the dominant male would be aggressive towards the other male, while conducting the study we made sure that we where not directly next to the enclosure but still in sight of them to record the data. We did this because we didn't want the animals to get stress by us being there and showing signs of aggression towards us.

Results
The results were all collected into and put into tables these
tables where turned into charts shown in figs 2&3. In figure one is a bar graph
which shows the number of each type of behaviour and shows which behaviours are
shown by the dominant male. This bar graph shows the total number of behaviours
collected from all the fifteen minute ethograms. Figure two shows a pie chart
which shows the

percentage of behaviours that the dominant male showed.
What do they mean
These results mean that the behaviour shown in the graphs show
that the dominant male does not show many aggressive behaviours towards the other
male. these graphs show that the dominant male spends most of his time eating and moving around with another sizable amount of time grooming either by itself or being groomed by the other male.
Conclusion
In conclusion this data means that the dominant male may not show
signs of aggression to the other male however the less dominant male does show submissive
behaviours like grooming the dominant male, to fully confirm this more studies
would have to be done however on this basis of study the dominant male does not
so a large amount of aggression toward the submissive male.
