A Spread Ash Pomeranian show crest pigeon, showing one of the forms of feather crest that pigeons may possess. From a genetic perspective, there are two loose ancestral clades of pigeons, but there is striking genetic homogeneity due to frequent interbreeding and human directed cross-breeding; pigeon fanciers often do not enforce breed ...
A 2014 genetic study (based on coalescent theory and on "sequences from most of the genome" of three individual passenger pigeons) suggested that the passenger pigeon population experienced dramatic fluctuations across the last million years, due to their dependence on availability of mast (which itself fluctuates). The study suggested the bird ...
