  <dc:description>Geographic variation in plumage color of &lt;i&gt;Chamaea fasciata&lt;/i&gt; (Wrentit) from northern California and southern Oregon is related to climate.  A new subspecies, &lt;i&gt;Chamaea fasciata margra&lt;/i&gt;, is described from a disjunct population of southern interior Oregon.  Colonization of &lt;i&gt;C. fasciata&lt;/i&gt; in interior Oregon was perhaps from birds crossing coniferous forests via isolated balds of &lt;i&gt;Ceonothus&lt;/i&gt;.  Recent increases of Wrentits in interior Oregon may be in response to habitat alterations (deforestation, fires) and concurrent global warming.</dc:description>
