The birds avoided feeders that smelled of the latter two, however not those that smelled of honey bees or a common food additive. “Smell in birds is more typical than we thought before,” Celis-Diez tells The Scientist.SMELLY WORMS: Artificial victim worms suffered more bird pecks when they were placed near a dispenser (left side of image) of the aggregation pheromone of carpenter worm (Chilecomadia valdiviana) larvae.JUAN LUIS CELIS-DIEZWhile many avian-focused clinical manuscripts rework the outdated belief that birds cant smell, or cant smell much, proof to the contrary has been developing for some time, states Andrew Iwaniuk, a neurobiologist at the University of Lethbridge in Canada. More than half a century later on, Iwaniuk and his associates discovered that the turkey vulture (Cathartes aura) has perhaps the biggest olfactory bulb of all birds, along with a high number of olfactory nerve cells that link the nasal cavitys smell receptors with the brain, features a sign of a particularly sensitive sense of smell.Alongside work on the physiological basis of smell in birds were practical research studies showing that vultures, and later on wandering albatrosses and other seabirds, can choose up the scent of food– carrion in the case of vultures, and chemicals released by plankton on the oceans surface in the case of the wandering albatross.” Still, its just recently that researchers have actually started to study smell in a much broader variety of bird species for a broad spectrum of functions, including mate selection, subspecies identification, and navigation. Wilson-Rankins and Celis-Diezs current studies, neither of which Iwaniuk contributed to, are “2 great examples of that,” he adds.Iwaniuk suspects that numerous birds are really delicate to a little number of smells.
