Homing by olfactory cues has been the most researched topic in bird navigation research for many years. Homing pigeons and petrels use airborne cues for orientation under certain conditions. However, many experimental results do not clearly show that odors are the crucial stimuli. 

Many petrels and shearwaters approach their nest burrow, often located under forest cover, at night. When Leach s petrel Occanodroma leucorrhoa) return to their nest, they first hover over the spruce-fir canopy near their burrow. Then they plummet to the ground several meters downwind from their nest site and walk upwind to their burrows (Fig. 4.6). In still air, they landed closer to the burrow and followed a more roundabout route than in wind. With external nares plugged or olfactory nerves transected, displaced birds did not return to their burrows for 1 week. In a laboratory two-choice apparatus, breeding petrels... 

Another experiment used cod liver oil, crude krill extract, and the krill odor components trimethylamine and pyrazine, with phenylethanol (rose odor) as control. Several procellariiform species were attracted to krill extract. The krill odor components attracted giant petrels, cape petrels, blue petrels, Antarctic petrels, Kerguelen petrels, and black-browed albatrosses. Cape petrels were more attracted to trimethylamine than to pyrazine and cod liver oil hut blue petrels responded most to cod liver oil (Nevitt, 1999).
