...) – a mainstay of ornithological research for more than 50 years – cannot be used to explore orientation in all birds, as the output of the assay requires that birds attempt to ‘fly’ in the correct direction (something that larger birds/gliding birds are unlikely to do in a confined space). If the detection...
