Being a true, border-crossing genre, the field guides to birds provides a hitherto unexplored field for the scholar of intermediality. In the field guide descriptive prose is combined with images, maps, and transcriptions of birdsong. The images show a variety of attitudes towards birds as objects of art, ranging from very straight-forward paintings modelled on stuffed specimens, to vivid free-hand sketches capturing the birds in their natural habitat. The stances of the texts also differ – from anthropocentric views on the life of certain birds, to more or less scientific micro-articles. A certain, very peculiar form of transcription, offers the different examples of the author to transfer bird-song to text, a try that sometimes approach the domains of concrete poetry. This presentation primarily focuses on two Swedish field guides: Erik Rosenbergs Fåglar i Sverige (The Birds of Sweden), and Lars Jonsson’s Fåglar i Europa (The Birds of Europe), and explores the contextual differences and similarities that exist between them. Theoretical background for this presentation is the contemporary field of ecocriticism, as specified by scholars like Jonathan Bate, Terry Gifford, Cheryll Glotfelty, and Greg Garrard. Articles and longer studies by Thomas J. Lyon will also be referred to, as will intermedial studies on the connection between image and text by, among others, J. Hillis Miller, Jon Lykke, and W. J. T. Mitchell. Certain historical and anthropological aspects of birdwatcher’s community are taken into account by a reference to the essays of Mark Cocker.
