House Wren (Troglodytes aedon) Science Article 4
The current taxonomic status of the Trogliodytes aedon (House Wren) species group was evaluated by examining levels and patterns of isozyme differentiation. Traditionally,three major taxonomic groups of continental House Wrens have been recognized: (1) aedon (Northern House-Wren); (2) brunneicollis (Brown-throated Wren); and (3) musculus (Southern House-Wren). The isozyme data were converted to genetic distances and analyzed using UPGMA, Distance Wagner, Fitch-Margoliash, ‘minimum-evolution,’ and neighbor-joining algorithms.
