Troglodytes troglodytes - Winter wren:

Summary Information
Living Organisms / Animalia / Craniata / Aves / Passeriformes / Certhidae / Troglodytes / Species

This section is currently predominantly used in Wildpro to link different data types and demonstrate inter-relationships. Although it identifies that taxonomic interrelationships of species (see "header") it does not currently contain detailed information on the bird species itself. As WILDPro is developed, we will gradually convert these pages into full Species pages.

The taxonomy of birds is still under review and the A World Checklist of Birds by Burt L. Monroe, Jr and Charles G. Sibley (B89) has been chosen as the primary reference. The taxonomic structure will be amended when new editions or complete references are identified by the scientific world as the recognized primary references for taxonomy.
