Theoretical frame
Historically speaking, semiotics was concerned with living beings and their natural behaviours and interactions with their environment - the semeion was a part of ancient medical practice (Favareau, 2007). Semiotics as a tool to study living beings re-emerged during the twentieth century with Sebeok's work on zoosemiotics (Sebeok, 1968, 1972, 1993), as a way to understand animal meaning-making, using Peirce's sign theory (1868a, 1868b, Sebeok, 1994).
Aside from this, studying animals with language science tools was not common in the academic fields, especially among humanities, and a certain hostility toward such studies remained for a long time (Griffin, 1977), De Waal, 2013, p. 170). Yet, ethology had for a long time craved tools to research inside the “black box” of the mind (Eco, 1999, p.126), to understand how animals interacted with their environment, how they understood it and lived in it, and how to understand what Uexküll named the Umwelt (Uexküll, 2004, Kull, 1998).
Biosemiotics and zoosemiotics will be used in this project in a relevant (Deely, 1992) but quite rare way: as tools and models allowing a study in both human and animal Umwelt, especially regarding how humans perceive animals – corvids in this study – how corvids behave in a human environment – in this paper the city of Tartu – and how they interact with each other.
There currently are very few studies in comparative ethology or semiotics of culture applied to animals in Europe. While the method has begun to be applied in primatology in Japan (Matsuzawa, 2017), few species have been the subject of such studies apart from great apes, and even fewer are included in projects aiming to understand a whole ecosystem with its interactions and its tensions.
The urban environment, while well-known, is still barely studied from this perspective. Nonetheless, it has a rich biodiversity, and with the development of urbanisation and increasing population density, urban environments are a critical aspect of the coexistence between humans and other species. Consequently, making it necessary to better understand this environment and how to manage it with a more global vision. To do so, semiotics models and tools will be used here with other academic specialities – mostly ethology – and theories – especially relevance theory (Sperber & Wilson, 1989) according to the method of intertheoricity (Guillaume, 2014), which allows disciplines of different fields to work correctly together on complex problems, like animal tastes and preferences (Kreutzer & Aebischer, 2015), emotions (Delahaye, 2019) or sensitivity (Guillaume, 2014).
