Description
Lucy's warbler is the smallest species of New World warbler. It measures from 9 to 12 cm (3.5 to 4.7 in) in length and can weigh from 5.1 to 7.9 g (0.18 to 0.28 oz), thus being slightly smaller even than the warblers formerly placed in the genus Parula. Among standard measurements, the wing chord is 49 to 61 mm (1.9 to 2.4 in), the tail is 33 to 41 mm (1.3 to 1.6 in), the bill is 7.8 to 9 mm (0.31 to 0.35 in) and the tarsus is 15 to 17.5 mm (0.59 to 0.69 in). It is rather nondescript compared to other wood-warblers, being perhaps the palest species in its family. Its head and upperparts are pale gray, while underparts are whitish. It has a white eyering and a small, pointed bill. Both sexes have a rufous rump, a diagnostic field mark. Adult males also have a small rusty patch on their crown. Juveniles are paler, with a tawny rump and buffy wingbars. Lucy's warbler is closely related to Virginia's warbler, Nashville warbler and Colima warbler. The common name and binomial of this species commemorate Lucy Hunter Baird, daughter of ornithologist Spencer Fullerton Baird. Lucy's warblers inhabit riparian mesquite and brushy country of the southwestern United States and northwestern Mexico. It can nest in the driest vegetated stretches of the Sonora Desert and nest in possibly the driest habitats of any New World warbler.

Feeding Habits
Lucy's Warbler's diet primarily consists of small insects like beetles, caterpillars, bugs, leafhoppers, ants, bees, wasps, and spiders. They glean food from leaves, branches, and bark and often forage high in trees or on the ground, displaying agility by hanging inverted while feeding.
Habitat
Lucy's Warbler predominantly resides in the arid lowland riparian areas of the southwestern United States. They flourish in dense mesquite woodlands near streambeds and also inhabit mesic upland desert scrubs, desert grasslands, and xeroriparian vegetation along dry washes. These birds prefer regions typically below 3,000 feet but can be found in open woodlands up to 5,800 feet in central Arizona. Common vegetation within their habitat includes mesquite, tamarisk, acacia, hackberry, and elderberry. During the breeding season, lucy's Warbler may utilize various trees for nesting, such as willows, arrowweed, paloverde, and ironwood, in drier scrub and grassland areas. Post-breeding, they seek wetter climates for molting prior to migration. Winters are spent in similar conditions as breeding habitats, including riparian and thorn forests in Mexico, with occasional occupation of mesquite and tamarisk in Texas.
Nest Behavior
Female lucy's Warbler constructs the nest, which then serves for egg-laying. The species adapts to various cavities for nesting, showing flexibility.
Nest Characteristics
The nest of lucy's Warbler is typically found in cavities, with locations ranging from low heights to up to 20 feet. It's made from twigs, grass, and leaves, often lined with softer materials like hair and feathers. The nest dimensions are about 3.4 inches wide, 3 inches tall, and the cup within measures 2 inches across.

Behavior
Lucy's Warbler exhibit distinct traits during their active phases, predominantly around breeding times. Upon returning from migration, males stake territorial claims with incessant singing, especially dense in prime habitats. They are territorial, defending their areas with vigor through song duels and physical confrontation upon intrusion. Their courtship display is notable—males showcase their cinnamon rump patch and crest feathers to females in a characteristic posture. Both sexes partake in nesting duties, and post-breeding, they can be seen foraging in cohesive family units. Lucy's Warbler interactions with their environment reflect a life tailored to the specific nuances of their habitats, involving both competitive and cooperative behaviors.
