From a BBC producer and award-winning birder, a guide to the unusual birds that soar over cities around the world. From frigatebirds wheeling over Rio de Janeiro to bowerbirds displaying in the suburbs of Canberra, penguins in Cape Town to pelicans in San Francisco, and huge flocks of starlings roosting around the Colosseum in Rome, the world's cities are home to a remarkable array of feathered citizens. Through Stephen Moss's expert knowledge and insight, Urban Aviary provides a beautiful guide to some of the most extraordinary species of city birds that have become native, including helpful spotting hints and fact boxes for each bird, all of which are brought to life by Marc Martin's distinctive and beautiful watercolours.
