Description
Marc Naguib and Andrea Nemitz studied how early hunger marks male zebra finches for life, in a 2007 PLOS ONE article. Conditions in early growth shape many traits that decide how well an animal does. Most work stops at the youngest stages, but later youth may matter too.
Working with juvenile males, the pair tested how nutritional stress at that stage affects plumage ornaments, the feather displays males show. They also followed how attractive those males were as adults. Poor food in youth, it seems, leaves visible marks that persist. For females choosing mates, such marks may be honest news about a male's past.
