Adult Grace’s Warblers look very similar. They both have dark gray crowns and a white patch at the end of their yellow eyebrow, and a little bit at the back of the eye. Their back is also dark gray, and they have bright yellow throats and breasts.
They both have white bellies with black broken streaks on their sides, and they have two obvious white wing bars.
Their main, though less obvious difference, is in the outline of their eyering. They both have yellow eyerings, but a female’s outline is gray, while the male’s is black, and you can see it on the bottom half of the eye.

Habitat And Diet
You can find Grace’s Warblers in habitats with mature coniferous trees, particularly pine, oak, and spruce-fir forests.
Grace’s Warblers prefer to stay safe at the tops of the trees because it’s where they can hop from branch to branch among trees or hide among the pine needles. They also spend their time catching insects from this height or foraging among the leaves for the insects hiding underneath them.
Grace’s Warblers’ Song:
Nests of Grace’s Warblers are also found in the pine trees. They’re made of leaves, stems, and cocoon materials, and with fur and feathers to make them soft on the inside. Usually, they’re cradled on a high tree branch. Females lay three to five eggs with an incubation period of eleven to twelve days.
The Grace’s Warblers got its name from Grace Darling Coues, the sister of ornithologist Elliott Coues.
