Backyard Birds in Delaware: A Year-Round Seasonal Identification Guide

A 3.9–4.7-inch sprite with a solid black cap and bib framing bright white cheeks — the South’s own chickadee. Carolina Chickadees anchor Delaware feeding stations year-round and readily nest in backyard boxes. Their song is a four-note fee-bee-fee-bay, higher and faster than the Black-capped’s two notes.

The male is an 8.3–9.1-inch blaze of crimson with a black mask and proud crest; the warm-buff female sings too — one of few female songbirds that do. Cardinals are permanent residents in every Delaware county, thickest in hedgerows and suburban tangles. Pairs visit feeders together at dawn and dusk, and males sing cheer-cheer-cheer year-round.

A soft-gray 5.5–6.3-inch bird with a pointed crest, peachy flanks, and huge dark eyes. Titmice are permanent fixtures at Delaware feeders, hammering seeds open while holding them with both feet. Their ringing peter-peter-peter whistle carries through winter woods.

A plump 4.7–5.5-inch wren in rich rufous-brown with a bold white eyebrow and a slightly decurved bill. Carolina Wrens are year-round Delaware fixtures, famous for nesting in flowerpots, wreaths, and garage shelves, and for a loud rolling tea-kettle-tea-kettle song that carries far beyond the yard.

A brilliant 9.8–11.8-inch crested jay in azure blue, white, and black. Blue Jays are the alarm system of the Delaware yard, screaming jay-jay at hawks and cats, and caching thousands of acorns each fall — a single jay can plant an oak grove.

A plump, gentle 9.1–13.4-inch dove in soft gray-brown with a long pointed tail edged in white. Named for its mournful cooing, it whistles sharply on takeoff. Mourning Doves feed beneath Delaware feeders in every season and nest astonishingly early — sometimes with snow still on the ground.

North America’s smallest woodpecker (5.5–6.7 inches) is a Delaware backyard regular in every season. Black-and-white checkered wings, a clean white stripe down the back, and a tiny stubby bill separate it from the larger Hairy Woodpecker; males wear a small red patch on the nape.

A zebra-backed 9.4-inch woodpecker whose red runs in a wash from nape over the crown (males) — the namesake belly blush is faint. Red-bellies are among the most common Delaware feeder woodpeckers, and their loud rolling churr is a year-round soundtrack.

A compact 5.1–5.5-inch bird in blue-gray with a clean white face and breast and black cap. Nuthatches are the acrobats of the feeder, famously walking headfirst down tree trunks. Year-round residents of Delaware hardwoods and older neighborhoods, they call a nasal yank-yank.

A tiny 3.9–4.3-inch nuthatch of southern pinelands with a warm brown cap, white cheeks, and a white spot on the nape. Brown-headed Nuthatches travel in chatty family flocks, visit suet and sunflower feeders, and readily use nest boxes with 1-inch holes — a signature bird of Delaware pine yards.

The male is royal blue above with a rusty throat and breast and a white belly; females are grayer with blue wings. Bluebirds are year-round Delaware residents, shifting to berries in winter. A nest box on a post facing open mowed grass — 1.5-inch hole, no perch — can fledge two or three broods a season.

The familiar 7.9–11-inch thrush: gray above, brick-red below, yellow-billed. The dawn chorus over a Delaware lawn is built on its cheerily-cheerup phrases. Robins nest on porch lights and ledges, and big winter flocks descend on holly and hackberry trees across the state.

A slender 8.3–10.2-inch gray bird with white wing patches that flash in flight — and a voice that borrows everyone else’s. Mockingbirds imitate dozens of species and sing through moonlit nights. In Delaware they defend berry bushes and feeders against all comers, year-round.

A streaky 4.7–6.7-inch sparrow with breast streaks converging into one bold central spot and a long rounded tail it pumps in flight. Song Sparrows sing their bright three-note-and-a-trill song from Delaware marsh edges, creek willows, and garden hedges nearly year-round.

A handsome 6.3–7.1-inch winter sparrow with a bright white throat patch, yellow lores, and a crisp striped crown in white- or tan-striped forms. White-throats winter throughout Delaware’s brushy edges from October to late April, whistling their clear Old-Sam-Peabody song on mild winter days.

The only hummingbird that breeds in the eastern U.S.: 2.8–3.5 inches of emerald green, the male with an iridescent ruby-red gorget. Arriving in Delaware in April, it works salvia, bee balm, and feeders all summer, then slips south by late September. Change sugar water every two to three days in heat.
