A paradox of vertebrate brain evolution is the unexplained variability in the size of the
olfactory bulb (OB), in contrast to other brain regions, which scale predictably with brain size …

Forty years ago, Papi and colleagues discovered that anosmic pigeons cannot find their way
home when released at unfamiliar locations. They explained this phenomenon by …

Many species travel in highly organized groups,,. The most quoted function of these
configurations is to reduce energy expenditure and enhance locomotor performance of …

The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis
and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much …

The insect central complex (CX) is thought to underlie goal-oriented navigation but its
functional organization is not fully understood. We recorded from genetically-identified CX …

Pelagic birds, which wander in the open sea most of the year and often nest on small remote
oceanic islands, are able to pinpoint their breeding colony even within an apparently …

This article is part of a Special Issue “Chemosignals and Reproduction”. Chemical cues
were probably the first cues ever used to communicate and are still ubiquitous among living …

The relative size of olfactory bulbs (OBs) is correlated with olfactory capabilities across
vertebrates and is widely used to assess the relative importance of olfaction to a species' …

For a long time birds were assumed to be anosmic or at best microsmatic, with olfaction a
poorly understood and seldom investigated part of avian physiology. The full viability of …

During migratory journeys, birds may become displaced from their normal migratory route.
Experimental evidence has shown that adult birds can correct for such displacements and …
