Females build the nest, sometimes using material the male carries to her. The nest is a cup of twigs, pine needles, grasses, and rootlets. She may also use moose, horse, and deer hair, moss, and lichens. She lines this cup with fine hair and feathers, sometimes woven into the nest in such a way that they curl up and over the eggs. The nest takes approximately 10 days to build and is 3-4 inches across and 2 inches tall. The eggs are colored white with speckles of brown, reddish-brown, gray, or purplish gray on them. 1 to 7 eggs are laid and the incubation time is 12 to 13 days. | Females build the nest, sometimes using material the male carries to her.

They were once considered different species, but in 1973 the American Ornithologists' Union elected to merge them into what we now call the Yellow-rumped Warbler. The Myrtle form (S. c. coronata) was apparently separated from the others by glaciation during the Pleistocene, and the Audubon's form (''S. c. auduboni'') may have originated more recently through hybridization between the Myrtle Warbler and the Black-fronted or Mexican form (''S. c. nigrifrons''). There is an additional form, Goldman’s (''S. c. goldmani'') found in Guatemala. It resembles Audubon's but has a white lower border to the yellow throat and otherwise darker plumage; males replace the slate blue of Audubon's with black. |

Its ability to use these fruits allows it to winter farther north than other warblers, sometimes as far north as Newfoundland. | + | The Yellow-rumped Warbler is the only warbler able to digest the waxes found in bayberries and wax myrtles.

On the west coast, the Yellow-rumped Warbler is particularly fond of the fruit on laurel sumac. |
