Good morning, everyone. Today we're going to discuss the impact of urbanization on local wildlife. One key point is that many bird species have adapted to city life by changing their nesting habits. For example, peregrine falcons now nest on tall buildings instead of cliffs. However, some animals, such as hedgehogs, are struggling because gardens are becoming smaller and more fenced. Interestingly, a recent study in London found that urban foxes have developed larger brains to help them find food in complex environments. This suggests that evolution can happen rapidly in cities.
