Unexpected diversity of alternative reproductive tactics revealed in Water Rails (Rallus aquaticus)
Monogamy in birds was long considered a general mating system until molecular studies provided evidence of alternative reproductive strategies (ARS), which are now assumed to be present in ~90% of bird species. These ARS or tactics (ART), as we consider them in this study, include extra‐pair copulation, which can lead to extra‐pair paternity or extra ...
