AbstractThis article tells a history of bird banding—the practice of catching and affixing birds with durable bands with the intent of tracking their movements and behavior—by focusing on the embodied aspects of this method in field ornithology. Going beyond a straightforward, institutional history of bird banding, the article uses the writings of biologists in the US Bureau of Biological Survey and the US Fish and Wildlife Service to describe the historical practices of bird banding and the phenomenological experience of banding, both for the scientists and the birds (via their banding interlocutors). The article then presents the career and research of Margaret Morse Nice as an exemplar of the embodied practice of banding for the purposes of understanding bird behavior. Finally the article uses the example and heritage of Nice as well as banders and scientists like her to discuss a phenomenological approach common to any number of observation-based field biology disciplines (including, especially, ethology) and deep connections between human and animal subjectivities. And these connections, in turn, have implications for the environmental humanities, environmental conservation, and the ethics of knowing the nonhuman world.
