    Moths are illustrated in their natural resting postures, and there are also paintings of different forms, underwings and other details to help with identification. New descriptions and illustrations have been included for species that have been newly recorded in Britain and Ireland since the last edition of the guide was published. The text descriptions of all other species - covering field characters and similar species, flight season, life cycle, larval foodplants, and habitat - have been revised and updated where necessary, and particular attention has been paid to updating the distribution information, which is now supported by maps. The revised general introduction explains how the methods of identifying and recording moths have evolved over recent years with the advent of new technologies and as a result of data analysis.

    Representing a great diversity of habitats, from the Andes in the north down to the tundra and sub-Antarctic rainforest of Tierra del Fuego in the far south, Chile is the breeding ground or temporary abode of 473 known species including 9 found nowhere else in the world. Birds of Chile covers them all, embracing not only the mainland but points offshore such as Easter Island as well as the Antarctic Peninsula and adjacent islands, plus the Falklands and South Georgia. In addition to being a friendly and fruitful birding destination in its own right, Chile is the starting point for many Antarctic cruises.Succinct, identification-focused text and distribution maps share a page opposite each of the 97 color plates to allow quick and easy reference. Between the boldfaced English name and the scientific name comes the Spanish name as used in Chile; this is important, for birders will find their quest far more enjoyable and effectual if they can explain to Chileans exactly what they are looking at, think they are looking at, or hope to be looking at.Since Chile's list of resident species is yet far from conclusive, vagrants and rarities are also included. Indeed, some birds once thought to be accidentals in Chile have since proved to be regulars, including the Westland Petrel, Least Sandpiper, Cliff Swallow, and Golden-billed Saltator.
