Peak Crest (symbol cr) is a recessive morphological mutation located at the cr locus.


The crest consists of a patch of reversed feathers at the back of the pigeon's head. Instead of growing down towards the bird's rear, the crest feathers point upwards in the opposite direction.


Peak crest is an autosomal recessive mutation. This means that both parents need to carry the mutant gene for it to express in the next generation. As a recessive mutation, it is possible for this mutation to be carried by a bird who does not visually express it.

Shell and other crests

It appears that shell crest and some other crests are created by a genotype including peak crest with additional modifiers.
