Feeding Habits
Townsend's Warbler predominantly consumes insects, especially caterpillars, ants, bees, moths, beetles, weevils, stinkbugs, and spiders. They forage in the canopy, sometimes lower when feeding young, and eat seeds and leaf galls too. During migration, townsend's Warbler also feeds on nectar, and in winter, on honeydew from scale insects. Some townsend's Warbler eat mealworms, peanut butter, and suet from backyard feeders.
Habitat
Townsend's Warbler are typically found in mature coniferous and mixed forests with a preference for old-growth fir, spruce, and hemlock woodlands. The species occupy environments from sea level to subalpine altitudes, where tall trees and a lush understory are present. During migration, a range of habitats including thickets, woodlands, and even urban parks may be utilized. In winter, townsend's Warbler adapt to various habitats, from oak-coniferous woodlands to montane forests, often at middle to high elevations in areas such as California and Middle America.
Nest Behavior
The female townsend's Warbler selects and investigates potential sites, handles construction solo, and utilizes various plant materials. Nest-building precedes egg-laying, with care for eggs and young divided among the parents, embracing a typical small bird breeding strategy.
Nest Characteristics
Townsend's Warbler's nest is a bulky cup found on a main limb of conifers like spruce or fir at an average height of 36 feet. Materials include bark, conifer needles, twigs, and plant fibers, lined with moss, grass, and hair. Average dimensions are 4 inches across by 3 inches tall, with an inner cup of 2.4 inches wide and 1.5 inches deep.

Behavior
Townsend's Warbler exhibit unique territorial and breeding behaviors. Upon arrival at breeding grounds, males aggressively establish domains, vying with contenders for days to delineate territories. Pair formation ensues swiftly, lacking a distinct courtship display. During nesting activities, males exhibit behaviors akin to courtship, such as head bowing and wing flaring, which also serve as threats to rivals. Townsend's Warbler vigorously defend their territory, which serves both for nesting and sustenance, and even repel other bird species post-hatching. The presumed monogamous mating system of townsend's Warbler observes occasional deviations, with extra-pair coupling suggested by additional male presences. Both parents invest in offspring care, actively feeding and attending to the young.
