Smell and Foraging in Shearwaters and Petrels

BIRDS of the order Procellariiformes (the tube-nosed swimmers: albatrosses, shearwaters and petrels) are unusual in the development of their olfactory equipment, and some authors have suggested that these pelagic birds locate food by smell1–3. I report here positive responses from shearwaters and petrels to airborne odour trails controlled for visual cues.
