# "The growing enthusiasm for serious field-work... brings the rare bird within reach of every active worker, and invests him with a greater responsibility for correct identification than ever before. Since the basis of all knowledge is correct identification - not only of species, but of race, age and sex where possible - the time is ripe for a publication designed to arm the field-worker with such information, in a condensed form, as will enable him to identify in the hand the rare species and 'extra-limitals' which could conceivably come his way in the course of trapping and bird-ringing." Volume 1: The genera - cettia; locustella; acrocephalus; hippolais. Volume 2: The genus - phylloscopus. Volume 3: The genus - sylvia. Each volume contains a table of measurements, and a key to genera and species. Field Guides numbers 7, 8 and 9 in the BTfO series of Identification Guides.
