The ecological races and the dual nature of reproductive isolation in birds: can the near-species morpho-geno-taxonomy display, in a simple appropriate way, all the various dimensions of population divergence in neuro-complicated organisms?

Three basic properties of the biological species of Ernst Mayr (genetic species, reproductive species, ecological species) are used here for the analysis of "taxonomic species problem" in birds. A priory each "property" is an independent source of key-information on populational diversity in the context of its historical background and prospects for future survival. Yet it is clear, that only in a case when these properties are congruent and coherent in the genesis of their particular new "states" - during process of divergence - we can say about triune in properties single biological species as something real, and about taxonomic species as a true equivalent of this reality. In fact, the vision of these properties in terms of syngenesis is a prejudice inherited by both, BSC and PSC taxonomic templates, from the biased absolutisation of genetic causation in the neodarwinian school of thinking. This absolutisation is the root of all evil with regard to own problems of near-species taxonomy, in particular in the attempt to solve them mainly through the calculation of genetic or phenetic distances...
