Query: Behavioural biology has come of age

With so many new animal behaviour textbooks coming onto the market, we seemto be spoilt for choice. I really enjoyed reading this one, however. Unlikeall the other ethology textbooks that I know of, this one is edited, so youdont just get one particular point of view. Despite this, there are nogreat differences in style between the different chapters, which makes thisbook very readable. On the one hand, there is some kind of historicalcontinuity, as the book is firmly based on Tinbergens `four whys. On theother hand, this book has a very modern feel to it, with plenty of spacegiven to topics such as neuroscience, cognition, animal welfare andconservation biology. The reference list is up to date and there is plentyof cross-referencing within the book. Also, the book has a very usefulglossary. This is an excellent book for undergraduate animal behaviourcourses, but it is also a very good read for lecturers and researchers inthis field.
