Tristan Donovan
Chicago Review Press, 2015.

An engaging read about the wild animals that live in cities with us — from raccoons in Berlin to leopards in Mumbai, rattlesnakes in Phoenix and African land snails in Miami, to foxes in London and subterranean crabs in Rome.

These animals have come to be in cities in many ways. Raccoons are not native to Berlin, but were escapees after the brief fad for raccoon coats in the early days of automobiles. Foxes in London had the city built up around them – it’s not that they were pushed out of the city and moved back, but they stuck around when new food sources presented themselves. African land snails were imported by accident.

Living in the city affects the animals in many ways, — good, bad, and neutral. Bird song has to change to adapt to city noise, such as getting louder, changing pitch, or both; birds colliding with skyscrapers is a problem for Chicago, which is on the Great Mississippi flyway. In many cases, such as coyotes and foxes, the animals live longer, healthier, and with much smaller ranges than in the wild. The smaller ranges happen because food is more abundant; this results in greater density, which can be a problem if there’s an infectious disease outbreak such as mange. Another change that happens across many species is animals becoming nocturnal in the city, as that helps them avoid humans.

Donovan talks to people doing on the ground research and control of animal species, and examines the issues using references that range from scholarly articles and to general interest books, news articles, and blog posts. In the final chapter (which provides a good, inspiring end to the book), he looks at how we can use cities as conservation agents and not only improve them as homes for the animals that live with us, but bring more animals into the city.
