Indigo bunting

This time of year, from late spring to summer, male adult indigo buntings transform into a brilliant deep blue. They fly to a high perch – like our cheerful friend atop a sunflower – and sing from morning to night to try to catch the attention of females. Indigo buntings are members of the “blue” clade (subgroup) of the cardinal family.
