The greаt bоwerbird аnd sаtin bоwerbird bоth construct bowers to attract potential mates; however, these bowers differ greatly. The great bowerbird collects mostly light colored objects (with an occasional red highlight), whlie the satin bowerbird looks for blue objects.  Let’s say that you discover that these species can produce viable young (e.g., if mated at a zoo through artificial insemination). This would then suggest that these unusal mating practices could result in reproductive isolation because female satin bowerbirds are looking for dark blue bowers, while female great bowerbirds are looking for light objects (or red). Ultimately, these behaviors enforce reproductive isolation that has likely resulted in
