Other pigments are produced by the bird during this process that get deposited into the hard shell. Because many of the hybrids born of interspecies unions die young or are otherwise incapable of passing on their genes themselves, this process is not considered to be evolutionarily successful. What does a female bird look for in a male’s song? The material from which the nests are made can also be used as camouflage.
