Abstract:

Patterns of food caching in birds are examined with emphasis on biases found in the literature. I found that small, tropical, carnivorous or frugivorous cachers are often neglected. The concepts of short versus long term caches and scatter versus larder hoards, while heuristically useful. artificially polarize what are in nature continua. Finally, using a levels of analysis approach, I discuss the role of food abundance, rather than scarcity, in the evolution of this behaviour.
