Beloved as the herald of spring, cuckoos have held a place in our affections for centuries. The oldest song in English celebrates the cuckoo's arrival, telling us that 'Sumer is icumen in'. But for many other birds the cuckoo is a signal of doom, for it is Nature's most notorious cheat. Cuckoos across the world have evolved extraordinary tricks to manipulate other species into raising their young. How do they get away with it? In this enormously engaging book, naturalist and scientist Nick Davies reveals how cuckoos trick their hosts. Using shrewd detective skills and field experiments, he uncovers an evolutionary arms race, in which hosts evolve better defences against cuckoos and cuckoos, in turn, evolve novel forms of trickery. This is a fascinating corner of Darwin's 'entangled bank', where creatures are continually evolving to keep up with changes in their rivals. Lively field drawings by James McCallum, and remarkable photographs, show cuckoos in action: from the female cuckoo laying her beautifully disguised egg, to the cuckoo chick ejecting the host's eggs and young from the nest to ensure it gets the full attention of its foster parents. Cuckoo offers a new insight not only into the secret lives of these extraordinary birds, but also into how cheating evolves and thrives in the natural world.

Σε μια μικρή πόλη της δυτικής Νιγηρίας τέσσερα νεαρά αδέλφια –ο μικρότερος είναι εννιά και ο μεγαλύτερος δεκαπέντε– εκμεταλλεύονται την απουσία του πατέρα τους από το σπίτι για να πάνε για ψάρεμα στο απαγορευμένο κοντινό ποτάμι. Εκεί θα συναντήσουν έναν επικίνδυνο τρελό που θα προφητεύσει ότι ο μεγαλύτερος αδελφός θα δολοφονηθεί από ένα από τα αδέλφια του. Αυτή η προφητεία θα σταθεί η αφορμή να διαλυθεί ο ισχυρός δεσμός τους και η αφετηρία μιας αλυσίδας τραγικών γεγονότων σχεδόν μυθικών διαστάσεων. Μια ιστορία αγάπης, μίσους και εκδίκησης που διαδραματίζεται με φόντο τις κοινωνικοπολιτικές εξελίξεις στη Νιγηρία της δεκαετίας του ’90. Μια συγκλονιστική αφήγηση με τη φωνή του μικρότερου αδελφού, του Μπέντζαμιν, και εξαιρετική χρήση της γλώσσας. Αναφορές στην αφρικάνικη φύση, στους μύθους και τις δοξασίες της Νιγηρίας, καταγραφή της καθημερινότητας με κύριο άξονα τη σύγκρουση μεταξύ παραδοσιακού και δυτικού τρόπου ζωής, σε ένα έξοχο πρώτο βιβλίο ενός λογοτέχνη που αξιοποιεί με μοντέρνο τρόπο την αφρικάνικη αφηγηματική παράδοση και φαίνεται να έχει μακρά καριέρα μπροστά του.

Τέσσερις φίλοι και συμφοιτητές μετακομίζουν, μετά την αποφοίτησή τους, στη Νέα Υόρκη για να φτιάξουν τη ζωή τους – άφραγκοι, χαμένοι, με μόνο τους στήριγμα τη φιλία τους και τις φιλοδοξίες τους: Ο ευγενής, ωραίος Γουίλεμ, επίδοξος ηθοποιός· ο Τζέι Μπι, ζωγράφος από το Μπρούκλιν, που προσπαθεί να κατακτήσει τον καλλιτεχνικό κόσμο∙ ο Μάλκολμ, αρχιτέκτονας σε μια σημαντική εταιρεία∙ και ο Τζουντ – ο ιδιοφυής, αινιγματικός Τζουντ. Όπως περνούν οι δεκαετίες, οι σχέσεις τους βαθαίνουν, αλλά και σκοτεινιάζουν, καθώς τις χρωματίζουν ο εθισμός, η επιτυχία, η περηφάνια. Ωστόσο η σπουδαιότερη πρόκληση, συνειδητοποιούν όλοι, είναι ο ίδιος ο Τζουντ, πλέον ένας απίστευτα χαρισματικός δικηγόρος μα και ένας άνθρωπος ολοένα και πιο διαλυμένος, με το σώμα του και τον νου του σημαδεμένα από τους ανείπωτους τρόμους της παιδικής του ηλικίας – κυνηγημένος από τραύματα που φοβάται ότι όχι μόνο δεν θα ξεπεράσει ποτέ, αλλά και θα τον ορίζουν για πάντα. Με πρόζα πλούσια και λαμπρή, η Γιαναγκιχάρα γράφει έναν τραγικό, υπερβατικό ύμνο στην αγάπη, μια αριστοτεχνική απεικόνιση του σπαραγμού, της τυραννίας της μνήμης και των ορίων της ανθρώπινης αντοχής.

In this fascinating new book, Nick Davies describes the natural histories of these brood parasites and examines many of the exciting questions they raise about the evolution of cheating and the arms race between parasites and their prey. Brood parasites fill their armory with adaptations including exquisite egg mimicry, rapid laying, ejection of host eggs, murder of host young, chick mimicry and manipulative begging behavior: ploys shown by recent research to have evolved in response to host defense behavior or through competition among the parasites themselves. While many host species appear defenseless, accepting parasite eggs quite unlike their own, many are more discriminating against odd-looking eggs and some have evolved the ability to discriminate against odd-looking chicks as well. How is this arms race conducted? Will defenseless hosts develop defenses in time, or are there constraints which limit the evolution and perfection of host defenses? And why are so few species obliged only to lay eggs in host nests? Have host defenses limited the success of brood parasitism, or is it in fact much more common than we suspect, but occurring mainly when birds parasitize the nest of their own kind? All of these puzzles are examined in descriptions of the natural history of each of the groups of parasites in turn. Here is a book with wide appeal, both to amateur naturalists fascinated by this most singular and macabre of behaviors and by ornithologists and ecologists interested in the evolution of ecology and behavior. The story takes us from the classic field work earlier this century by pioneer ornithologists such as Edgar Chance, Stuart Baker, Herbert Friedmann and others, through to the recent experimental field work and molecular techniques of today's leading scientists. We visit brood parasites in Europe, Asia, Japan, Africa, Australasia, and North and South America, to look at some of the worlds most interesting birds and some of biology's most interesting questions, many of which still beg answers from ornithologists in the future. Brilliant illustrations by David Quinn illuminate the species discussed, showing many behaviors never before illustrated and conveying the thrill of watching these astonishing birds in the wild.

Much of Charles Darwin's groundbreaking work as an evolutionary biologist stemmed from his study of birds. It is universally acknowledged that Darwin's observation of bird groups and species like the Galapagos finches, mockingbirds, and rock doves was critical to the development of his theories on natural selection, evolution, and sexual selection. The significant number of diverse birds that Darwin covered in his published works represents a most substantial ornithological contribution. His major books alone contain reference to and consideration of almost 500 bird species, as well as interesting and pertinent discussion of over 100 ornithological topics. "Charles Darwin's Birds" is a comprehensive treatment of Darwin's work as an ornithologist. Clifford Frith discusses every ornithological topic and bird species that Darwin researched, providing a complete historical survey of his published writing on birds. Through this, we learn how Darwin became an increasingly skilled and eventually exceptional ornithologist, and how his relationships grew with contemporary scientists like John Gould. It examines how Darwin was influenced by birds, and how the major themes of his research developed through his study of them. The book also features 4 appendices, which contain brief accounts of every bird species Darwin wrote about, basic ornithological information about each of the species, and a listing of where the species appears in Darwin's work.
