Narrator 1’ Now listen to part of a lecture in a biology class. The professor is discussing the types of habitats for wildlife found in cities.
Professor:
Although cities have not generally been associated with wildlife, there are many species that have
become so much a part of the urban landscape that they are, for the most part, unnoticed neighbors. For example, in New York’s Central Park, almost 300 species of birds have been identified. Urban parks certainly provide some of the world’s safest and in many ways, best wildlife habitats, and as the natural habitats shrink, well, these urban parks will become more and more important to the conservation of wildlife, including not only birds... but, uh... but also freshwater animals and, even small mammals. So, as you see, man-made areas are one important type of habitat in cities. But artificial structures in the urban landscape...these can also provide a home for animals that adapt to life in the city. For instance, chimney swifts are birds that originally lived in hollow trees, but now chimney swifts are commonly found in the long brick chimneys in factories or other vertical shafts in tall buildings. Think about it. A city has more chimneys than there are hollow trees in a forest of equal area. Consequently, these birds flock to the city. Another case of adaptation is the urban drainage system, which is usually made up of concrete ditches, and they naturally attract stream and marsh animals. Again, to use New York City as an example, probably 250 species of fish are found in the harbor, many of which make their way into the pools and ponds and ditches in the New York drainage system. In Boston, the Back Bay was actually designed to create habitats and attract marshland wildlife to the city.
