The study looked at how the number of birds in different areas affects how they are spread out. They found that the amount of birds in an area influences how they are distributed locally. The researchers used a mathematical model to analyze this relationship and found that the overall abundance of birds in the UK impacts how they are spread out regionally. They also discovered that different bird species have different patterns of distribution based on their abundance. This research helps us understand how bird populations are distributed and how factors like abundance and behavior play a role in shaping their spatial patterns.
