These are probably the best known and most frequently encountered wood warblers. Although variable, all yellow-rumped warblers possess a bright yellow rump, which is shared with only 2 other species. The yellow-rumped’s unique ability to digest the waxes in bayberries allows it to winter farther north than other warblers. Built in June on the fork of a horizontal conifer branch near the trunk at low to moderate height, the yellow-rumped Warbler’s nest contains 3 to 6 eggs. Polytypic (6 ssp.). Length 5.3".

Spring male: crown and back blue-gray streaked with black. Yellow crown patch, distinct rump patch, and patches at sides of breast. White or yellow throat. Black streaks on upper breast and side. White wing bars. White spots in outer
