From Jacob Silver:

Re: Tit-for-tat: birds found to repay wartime help (July 6): These findings indicate the comprexity of species interaction, in this case, of birds. If you think about it, survival for these tiny dinosaur descendents is not a simple thing, what with preditors evolving along with them. In retrospect to the research findings, reciprocity among small birds is a logical response. Of course this reciprocity requires that individual birds recognize each other and themselves. Why would anyone think they didn’t? And it is nice to learn the complexity of bird behavior before we clear cut and kill them all out.
