Description
Grace's warbler is a small bird, 11–13 cm long. It is mostly gray on top, with broken black streaks across the back and flanks and two white bars on the wings. The throat and breast are a vibrant yellow, and the rest of the underparts are white. It has a yellow half-eye ring under the eye and a long yellow "eyebrow" stripe that starts at the base of the beak and runs above the eye, fading to white after it passes the eye.

Feeding Habits
Grace's Warbler primarily consume insects like beetles, flies, dragonflies, caterpillars, and spiders. They forage nimbly in the upper parts of mature pines, along smaller branches and in needle clusters, occasionally in oaks, and may catch prey in flight or on the ground.
Habitat
Grace's Warbler is typically found in mature pine and pine-oak forests situated in mountainous regions that range from lowland pine savannas to high-elevation spruce-fir forests. Preferring an elevation ranging from mid to high altitudes, grace's Warbler thrives in a climate suitable for dense coniferous vegetation. Specifically, in areas like Arizona and New Mexico, grace's Warbler is associated with forests containing varieties of pines such as ponderosa and Chihuahua, and oaks like Gambel’s and Emory. While migrating or wintering, grace's Warbler seeks out similar habitats, avoiding low-elevation deserts and similar non-forested environments.
Nest Behavior
The female grace's Warbler is responsible for selecting the nest site and constructing the nest. Egg-laying patterns and the timing of nest building are not specified.
Nest Characteristics
Grace's Warbler's nest is typically situated within a pine needle cluster near the outer edge of a tree, over 30 feet above ground. It is constructed as a flat cup combining plant fibers, wool, animal hair, and string, bound with spiderweb. The interior is lined with feathers, fine grasses, rootlets, and hair. The nest measures approximately 2.7 inches across and 2.2 inches in height, with the inner cup being 1.8 inches across and 1.3 inches deep.

Behavior
Grace's Warbler demonstrate distinct territorial behavior soon after returning to their breeding areas, with males singing to attract mates and establish boundaries. This courtship, including song and following females, spans several weeks—a lengthy period amongst warbler species. Nesting is a female-led endeavor, from site selection to construction, while males actively protect territory and repel rivals. Both sexes participate in incubation and rearing the young, and post-fledging, grace's Warbler families forage collectively, often joining other warblers and woodland species like Mexican Chickadees and Bridled Titmice, indicating a social aspect to their otherwise territorial nature.
Distribution Area
Grace's warblers breed from the south-western United States to Nicaragua and winter in their breeding range from north-eastern Sinaloa and north-western Durango south. They are almost always found in pine forests, even in migration, though at the northern end of their range (in southern Nevada and Utah and southwestern Colorado) they occur in spruce-fir forest. They prefer open, "parklike" woods, and in some areas such as northern Arizona they prefer an understory of Gambel's oak. In the United States and northern Mexico they typically occur at altitudes of 1,800 to 2,700 metres (5,900 to 8,900 ft)); farther south they may occur as low as 250 m. They are common in some localities, and in areas of the Mosquitia of Nicaragua where the only tree is the Caribbean pine, Grace's warblers may be the only bird seen.
