It was, fortunately, one adult male whom I'd named David Greybeard -- and by the way, science at that time was telling me that I shouldn't name the chimps; they should all have numbers; that was more scientific.
Felizmente, era um macho adulto  de nome David Greybeard [barba cinzenta]. Na época, a ciência ditava-me  que não devia dar nomes aos chimpanzés deviam todos ter números,  que era mais científico.
