We know a good deal about brain lateralization in birds and a good deal about animal
welfare, but relatively little about whether there is a noteworthy relationship between avian …

Many vertebrates show lateralized behaviour, or handedness, where an individual
preferentially uses one side of the body more than the other. This is generally thought to be …

Slight departures from bilateral symmetry are usually associated with reduced fitness. Here
we show that an insular freshwater population of Gasterosteus aculeatus exhibits spatial …

Evidence for foot preferences has been reported in parrots and the majority of parrot species
uses the left foot to hold and process food objects. Here we assessed the footedness of ring …

Brain and behavioral asymmetries (termed" lateralization"; eg, preferential eye‐use) have
been mostly described in controlled laboratory conditions, although striking similarities of …

The interest in lateralisation, which has grown exponentially over the last two decades, led
to the organisation of a symposium entitled ''Lateralised Behaviour'', the first to be set up …

Behavioral lateralization at the population level is widespread across vertebrates, with
considerable variation among species. However, evidence for individual-level and sex …

Behavior is lateralized when it is performed preferentially by one side of the body, and this
phenomenon is seen across a wide range of vertebrate taxa. Furthermore the brain and …

Objective The objective of the current study was to investigate the lateral dominance for a
bimanually coordinated natural feeding behavior in semi‐wild chimpanzees. Methods …

Most studies of lateralized behaviour have to date focused on active behaviour such as
sensorial perception and locomotion and little is known about lateralized postures, such as …
