Methods used to study memory able to show that food-caching birds have much larger hippocampus’ than non food-caching birds. Without techniques such as cell labeling, neuronal staining and careful post mortem analysis, these comparison studies would be impossible. Songbirds are excellent animal models for studying learning and auditory memory. These birds have highly developed vocal organs, which give them the ability to create diverse and elaborate birdsongs. Neurotoxic lesions can be used to study how specific brain structures are key for this type of learning and scientists can also manipulate the environment in which these birds are raised. In addition, with functional MRI the response
