This editorial introduces Archaeo-Ornithology as a distinct field of inquiry and discusses its multidisciplinary background and potential contribution to a more nuanced characterisation of changing human-animal interfaces through time and space. We propose a new conceptual modelgrounded in the analysis of 'triangles of interaction'to elucidate the interactional dynamics which underpin varying human-animal relationships. The utility of this approach is demonstrated by exploring the example of anthropogenic space as a key context of human-bird figurations. Each contributing paper of the special issue, which will be introduced in more detail below, foregrounds different aspects and emphasises varying dimensions of the triangle, thus contributing in different ways to archaeo-ornithological research. As highlighted throughout the introduction, however, archaeo-ornithological approaches are not only capable of shedding new light on old questions about the past, they also have the potential of addressing some pressing contemporary quandaries, including continuing debates on the Anthropocene.
