... in response to Hippocampus Evolution
  1. Catch or Cache???

    I believe a correction is needed here.  Bird species that "cache" their food have a larger HC than species that are opportunistic feeders or those who "catch" their food.  Food caching in birds like the Clark's Nutcracker, Acorn Woodpecker, and others would require a larger and more functional HC with regards to finding their way back to their stores than simply remembering where you caught a bug or pigeon.  

    The following publications support this.

    http://www.ncbi.nlm.nih.gov/pubmed/2611638 "The hippocampal complex of food-storing birds" and
    http://www.ncbi.nlm.nih.gov/pubmed/8680849 "Differences in hippocampal volume among food storing corvids".

    Catch vs. Cache.  An easy mistake to make but one that has a lot of impact here.
