Species generally interbred among the same population of species according to the season and hence they loose mating opportunities.  Although being sexually compatible they do not interbreed. Behaviorally, a biological clock in species naturally sets breeding cycle according to the resources availability, suitable nesting sites and mating opportunities.

vodomira [7]
