The chemical basis of a signal of individual identity:shell pigment concentrations track the unique appearance of Common Murre eggs
In group-living species with parental care, the accurate recognition of one's own young is critical to fitness. Because discriminating offspring within a large colonial group may be challenging, progeny of colonial breeders often display familial or individual identity signals to elicit and rec...
