Feeding

According to what is known from limited studies, Grace’s warbler, like the great majority of warblers, feeds only on insects and spiders. It spends the majority of its time high in pine trees.

Habitat

Mountain pine-oak woods. During the breeding season, found primarily on the tops of pine trees, but occasionally in thickets of spruce, fir, and oak in the Southwest’s higher mountains. In the winter, inhabits pine-oak forests in the mountains of Mexico.

Behavior

Grace’s warblers’ breeding behaviors are largely unknown, as nests are quite rare. The nest is a little cup made of plant fibers, lined on the inside with hair and feathers, and perched high above the ground on a branch of a tree, generally a pine. The female produces three to five white or cream-colored eggs with brown speckles and a ringed bigger end.
