The hippocampal complex of food-storing birds.
Three families of North American passerines--chickadees, nuthatches and jays--store food. Previous research has shown that memory for the spatial locations of caches is the principal mechanism ofExpand

Hippocampal specialization of food-storing birds.
In a study of 52 individuals belonging to 35 species or subspecies of passerine birds it was shown that the volume of the hippocampal complex relative to brain and body size is significantly largerExpand

Evolution of spatial cognition: sex-specific patterns of spatial behavior predict hippocampal size.
In a study of two congeneric rodent species, sex differences in hippocampal size were predicted by sex-specific patterns of spatial cognition. Hippocampal size is known to correlate positively withExpand

The Evolution of Multiple Memory Systems
The existence of multiple memory systems has been proposed in a number of areas, including cognitive psychology, neuropsychology, and the study of animal learning and memory. We examine whether theExpand

Spatial memory and adaptive specialization of the hippocampus
The hippocampus plays an important role in spatial memory and spatial cognition in birds and mammals. Natural selection, sexual selection and artificial selection have resulted in an increase in theExpand

Abstract Black-capped chickadees ( Parus atricapillus ) store food in a scattered distribution in their winter home range. Several hundred food items may be stored in a day, each in a separate cacheExpand

Food storing by marsh tits
Wild marsh tits (Parus palustris) were allowed to hoard radioactively labelled sunflower seeds, which were subsequently found using a portable scintillation counter. Seeds were stored singly, inExpand

Hippocampus and memory for food caches in black-capped chickadees
Black-capped chickadees and other food-storing birds recover their scattered caches by remembering the spatial locations of cache sites. Bilateral hippocampal aspiration reduced the accuracy of cacheExpand

Females have a larger hippocampus than males in the brood-parasitic brown-headed cowbird.
Females of the brood-parasitic brown-headed cowbird (Molothrus ater) search for host nests in which to lay their eggs. Females normally return to lay a single egg from one to several days after firstExpand

Hippocampal volume and food-storing behavior are related in parids.
The size of the hippocampus has been previously shown to reflect species differences and sex differences in reliance on spatial memory to locate ecologically important resources, such as food andExpand
