* Vast Distribution: Squirrels live across a huge range of habitats and continents, making a global census extremely difficult.
* Population Fluctuations: Squirrel populations are constantly changing due to factors like food availability, predation, and disease.
* Difficult to Count: Squirrels are elusive and often hide in trees, making them hard to track and count.
Instead of a precise number, we can talk about general estimates:
* Millions: Scientists estimate there are likely millions of squirrels worldwide.
* Abundant in Some Regions: Squirrels are considered abundant in certain areas, especially in North America and parts of Europe.
If you're curious about squirrel populations in a specific area, you could look for research done by wildlife biologists in that region.
