In a study by Nowicki et al. (2002), the researchers compared brain development and song learning in two groups of nestling swamp sparrows: an experimental group that was given 30 percent less food, and a control group. Their results showed that the experimental group displayed lower HVC volume and lower song copy quality. What hypothesis was Nowicki et al. (2002) testing, and what is the proposed reasoning for their findings?
