So, you want to study zoo animals in your study.
Designing experiments in zoos can be difficult as you will often have limited control over extraneous variables (e.g., feeding times, groups sizes, husbandry, visitor numbers can all change on a regular basis!). One further consideration of zoo studies is that you may have to employ a single case-study design. These are often not suitable for typcially-used statistical analysis methods, so take time to think about this prior to undertaking a project.
Make sure that you make a note of any potential sources of uncontrolled variability before you start data collection, as these may need to be accounted for in your data analysis.
