What is this bird&#039;s taxonomic family and who are its North American relatives? Can you identify this species?&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Response:&lt;/strong&gt; This is an adult male orange-breasted bunting, &lt;em&gt;Passerina leclancherii&lt;/em&gt;. This seemingly glow-in-the-dark passerine  is placed into the Cardinalidae family of cardinal-grosbeaks. This species is endemic to Mexico where it resides in dry forests and shrubland in the tropics and subtropics. These birds and their close relatives feed on seeds in the winter and insects in the summer, and they have correspondingly smaller bills than most cardinalids. The cardinalids are also known for being dimorphic, and the males often have dramatic, brilliant colouring (although I think the females are very beautiful as well). &lt;/p&gt;&lt;p&gt;This bird has a number of beautiful North American relatives, all of which are migratory; breeding in North America and wintering in Central and South America. These species include the blue grosbeak, &lt;em&gt;P. caerulea&lt;/em&gt;; lazuli bunting, &lt;em&gt;P. amoena&lt;/em&gt;; &lt;a href=&quot;http://www.guardian.co.uk/science/punctuated-equilibrium/2011/sep/01/4&quot;&gt;indigo bunting&lt;/a&gt;, &lt;a href=&quot;http://www.guardian.co.uk/science/punctuated-equilibrium/2011/may/05/5&quot;&gt;&lt;em&gt;P. cyanea&lt;/em&gt;&lt;/a&gt;; varied bunting, &lt;em&gt;P. versicolor&lt;/em&gt;; and the &lt;a href=&quot;http://www.guardian.co.uk/science/punctuated-equilibrium/2011/may/04/4&quot;&gt;painted bunting, &lt;em&gt;P. ciris&lt;/em&gt;&lt;/a&gt;. Another congener, the rose-bellied bunting, &lt;em&gt;P. rositae&lt;/em&gt;, is endemic to Mexico. &lt;/p&gt;&lt;p&gt;This species has a sweet, lilting song that you might enjoy.
