“…Dubbeldam [1998] emphasizes its role in stereotyped behavior, but it might also be involved in motivational, emotional and cog-nitive aspects of behavior [see Parent, 1986]. Stewart et al [1996] and Mezey et al [1999] have looked at striatopallidal influences on passive avoidance learning in chicks, whereas in mammals, links with the cerebral cortex suggest that the striatopallidal complex could be important in cognitive processes Oberg and Divac, 1979].…”

“…Based on embryological, neuromorphological, cytoarchitectonic and cytochemical evidence, Karten [1969], Rehkäm-per and Zilles [1991] and Dubbeldam [1993Dubbeldam [ , 1998 have underlined the similarities between the mammalian neocortex and parts of the avian telencephalon. In primates, the best studied mammalian taxon, relative neocortex size has recently been shown to vary with traits that parallel our measure of feeding flexibility in birds [i.e.…”

“…The wulst features several primary areas, with projections from the thalamofugal visual system [Karten et al, 1973] as well as somatosensory areas [see Shimizu et al, 1995 for detailed references]. The striatopallidal complex is thought to be involved in the control of stereotyped, species-specific behavioral responses [Reiner et al, 1984;Dubbeldam, 1998]. Both the wulst and striatopallidal complex have also been implicated in the control of learned behavior [wulst: MacPhail, 1976;Shimizu and Hodos, 1989;Rogers, 1997, 2000;striatopallidal complex: Parent, 1986;Stewart et al, 1996;Mezey et al, 1999].…”

An innovation was defined as a food type or foraging technique stated to be 'noteworthy', 'unusual', 'unknown', 'rare', 'opportunistic', 'interesting', 'adaptable', 'strange', 'not noted before', 'not recorded', 'not mentioned' [see Lefebvre et al, 1997Lefebvre et al, , 1998 for examples and a detailed description of the procedure].…”

Within the avian telencephalon, the dorsal ventricular ridge (DVR) contains higher order and multimodal integration areas. Using multiple regressions on 17 avian taxa, we show that an operational estimate of behavioral flexibility, the frequency of feeding innovation reports in ornithology journals, is most closely predicted by relative size of one of these DVR areas, the hyperstriatum ventrale. Neither phylogeny, juvenile development mode, nor species sampled account for the relationship. Similar results are found when the hyperstriatum ventrale is lumped with a second DVR structure, the neostriatum. In simple correlations, size of the wulst and the striatopallidal complex is associated with feeding innovation rate, but the two structures are eliminated from the multiple regressions. Our results parallel those on primates showing a correlation between innovation rate and neocortex size and support the idea that the mammalian neocortex and the neostriatum-hyperstriatum ventrale complex in birds have similar integrative roles.

Several comparative research programs have focused on the cognitive, life history and ecological traits that account for variation in brain size. We review one of these programs, a program that uses the reported frequency of behavioral innovation as an operational measure of cognition. In both birds and primates, innovation rate is positively correlated with the relative size of association areas in the brain, the hyperstriatum ventrale and neostriatum in birds and the isocortex and striatum in primates. Innovation rate is also positively correlated with the taxonomic distribution of tool use, as well as interspecific differences in learning. Some features of cognition have thus evolved in a remarkably similar way in primates and at least six phyletically-independent avian lineages. In birds, innovation rate is associated with the ability of species to deal with seasonal changes in the environment and to establish themselves in new regions, and it also appears to be related to the rate at which lineages diversify. Innovation rate provides a useful tool to quantify inter-taxon differences in cognition and to test classic hypotheses regarding the evolution of the brain.
