SUMMARY
Measurements of the longest diameters of the olfactory bulbs and cerebral hemispheres of 46 species of birds are presented. These are compared in each species so that the relative size of the bulb is expressed in per cent of the diameter of the hemisphere. The relatively smallest bulbs are found in Passeriformes, Psittaciformes and Piciformes. The largest are in the Podicipediformes and Procellariiformes. Relatively large bulbs appear to be positively correlated with large hippocampal areas in the brain and aquatic habitat. Relatively small bulbs correlate with small hippocampal areas and tree living.
RÉSUMÉ
Rapport sur les mensurations du plus long diamètre des bulbes olfactifs et des hémisphères cérébraux de 46 espèces d'oiseaux. Ces mensurations sont comparées dans chaque espèce de façon à ce que la dimension relative du bulbe soit exprimée en pour‐cent du diamètre de l'hémisphère. Les bulbes relativement les plus petits se trouvent chez les Passeriformes, les Psittaciformes et les Piciformes; les plus grands, chez les Podicipediformes et les Procellariiformes. Des bulbes relativement grands se révèlent positivement en corrélation avec de grandes régions hippocampales du cerveau et l'habitat aquatique. Les bulbes relativement petits le sont avec de petites régions hippocampales et chez les animaux vivant dans les arbres.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
