type of attention, particularly since observers, associating it with the usual patterns of competition, have tended to interpret it quite literally, emphasizing its aversive effect. The words used by some ornithologists to describe specific behaviours speak volumes: conflicts, combats, challenges, disputes, attacks, chases, patrols, territorial defence, headquarters (frequently used in reference to the central point of the territory from which the bird sings), war paint (to describe the colours of territorial birds) … But, at a very early stage, certain ornithologists challenged these terminological practices, not because they anthropomorphize birds but because they tend to focus attention on competitive and aggressive behaviour associated with territorialization, to the detriment of other dimensions which seemed to them of crucial importance.

      That apart, as I was to discover in the course of my investigation, few ornithologists favour an approach based on ‘ownership’. The majority would prefer the definition proposed in 1939 by the American zoologist Gladwyn Kingsley Noble, ‘Territory is any defended area.’ This at least had the merit of being a relatively simple one, capable of describing almost all territorial situations. Depending on the various theories, a variety of functions would also be identified: a site can be defended in order to ensure subsistence, to protect birds from interference during the reproductive period, to provide a ‘stage’ for ‘promotion’ (a term encompassing all forms of exhibition, displays and songs), to ensure exclusive rights over a female or guarantee the stability of the same meeting place from one year to another, along with various other functions which will be examined in chapter 2. Very quickly, ornithologists realized that there was no one single way of establishing a territory but instead multiple forms of territorialization. This definition of an ‘actively defended area’ would be subject to a great many nuances as more discoveries on the subject came to light and as the multiplicity of different ways of becoming territorial were revealed. The boundaries would turn out to be far more flexible, negotiable and porous than early observations might have indicated, and, surprisingly perhaps, certain researchers would reach the conclusion that, for many birds, territories had other functions beyond simply that of protection against intrusion and ensuring exclusive use of a site. All of that will be examined in what follows.

      So, for example, in the historical inventory drawn up by the ornithologist Margaret Nice, I find a quotation from Walter Heape, who writes, in a book on emigration, immigration and nomadism published at the end of the 1920s, that

      territorial rights are established rights among the majority of species of animals. There can be no doubt that the desire for acquisition of a definite territorial area, the determination to hold it by fighting if necessary, and the recognition of individual as well as of tribal territorial rights by others are dominant in all animals. In fact, it may be held that the recognition of territorial rights, one of the most significant attributes of civilisation, was not evolved by man, but has been an inherent factor in the life history of all animals.12
