Orange-crowned Warbler vs Yellow-rumped Warbler (Leiothlypis celata vs Setophaga coronata): The Complete Backyard Identification Guide
Quick Answer: The Fastest Way to Tell Them Apart
The drab one and the butter-butt. Three rules:
- Rump: bright yellow = Yellow-rumped; plain olive = Orange-crowned.
- Wing bars: two white bars = Yellow-rumped; none = Orange-crowned.
- Face: thin eye-line and broken eye-ring = Orange-crowned; bolder mask and pattern = Yellow-rumped.
At-a-Glance Comparison Table
The two hardiest warblers, side by side. KEY rows separate fastest.
| Feature | Orange-crowned Warbler | Yellow-rumped Warbler |
|---|---|---|
| Scientific Name | Leiothlypis celata | Setophaga coronata |
| Length | 4.3–5.5 in (11–14 cm) | 4.7–5.9 in (12–15 cm) |
| Wingspan | 7.25 in (18 cm) | 7.5–9.1 in (19–23 cm) |
| Weight | 0.3–0.4 oz (8–11 g) | 0.4–0.5 oz (12–13 g) |
| Overall Shape | A drab, slim warbler — olive-yellow with a thin bill and almost no pattern | A hardy, active warbler — the “butter-butt” of winter feeders |
| Male Plumage KEY | Drab olive-yellow, faint streaking below, thin dark eye-line and broken eye-ring; the namesake orange crown is hidden (sexes alike) | Breeding male: blue-gray above, black mask and chest patches, bright yellow crown, sides and rump; white throat in the East (“Myrtle”), yellow in the West (“Audubon’s”) |
| Female Plumage | Identical, averaging duller | Browner and duller but keeps the yellow rump, crown patch and side patches |
| Bill Shape | Thin, sharply pointed, dark | Thin, pointed, dark |
| Tail | Shortish, plain olive | Dark with white spots, often flicked |
| Core Range | Breeds in the West and far north; winters across the southern US and Mexico | Breeds across Canada and mountain West; winters across the southern half of the US — the common winter warbler |
| Migration KEY | Migratory — an early spring and late fall migrant; winters in the South | Migratory, but winters farther north than any other warbler |
| Feeder Presence | Unusual for a warbler — visits suet, peanut butter and hummingbird feeders in winter | Suet, peanut butter and dried fruit in winter — the warbler most likely at a feeder |
| Favorite Foods | Insects gleaned from foliage; berries and suet in winter | Insects in summer; wax myrtle and bayberry fruit in winter — the key to its hardiness |
| Song | A loose trill that changes pitch and fades at the end | A loose, musical trill rising or falling at the end |
| Flight Call KEY | A sharp “tseek” | A flat, hard “chip” |
| Population Trend | Stable overall; one of the drabbest but hardiest warblers | Abundant and stable — a conservation success of adaptability |
Male Field Marks, Side by Side
Orange-crowned Warbler — Male
- Drab olive-yellow, faint streaks, thin bill.
- Broken eye-ring and thin eye-line.
- The orange crown is almost never visible in the field.
Yellow-rumped Warbler — Male
- Yellow rump, yellow side patches, yellow crown.
- Breeding male is crisp blue-gray with a black mask.
- The yellow rump flashes as it flycatches.
Female & Juvenile Marks, Side by Side
Orange-crowned Warbler — Female
- Identical, duller.
- Winters farther north than most warblers.
- Visits suet and jelly feeders in winter.
Yellow-rumped Warbler — Female
- Browner, but the yellow rump always shows.
- Eats berries other warblers cannot digest.
- Flocks roam winter woods and wax myrtle.
Part-by-Part Anatomy Breakdown
Every part offers a check:
| Body Part | Orange-crowned Warbler | Yellow-rumped Warbler |
|---|---|---|
| Rump | Plain olive | Bright yellow — always visible |
| Wing Bars | None | Two white bars |
| Breast | Faint blurry streaks on olive-yellow | Crisp black patches (breeding) or plain gray-brown (winter) |
| Face | Thin dark eye-line, broken eye-ring | Bolder dark mask, white eye-arcs |
| Side Patches | None | Yellow shoulder patches |
| Song | Loose trill that changes pitch and fades | Loose musical trill, rising or falling |
| Winter Diet | Suet, jelly, insects | Wax myrtle berries, suet, insects |
Song & Call Comparison
Orange-crowned Warbler
Song: a loose trill that changes pitch and trails off.
Calls: a sharp tseek.
Yellow-rumped Warbler
Song: a loose trill, rising or falling.
Calls: a flat, hard chip — learn it to find winter flocks.
Range & Seasonal Presence
The Orange-crowned Warbler breeds in the West and far north, wintering across the southern US — a drab but hardy migrant.
The Yellow-rumped Warbler breeds across Canada and the mountain West and winters farther north than any other warbler, on a diet of wax-coated berries.
Feeder Behavior & Favorite Foods
- Orange-crowned: suet, peanut butter and jelly feeders in winter — unusual for a warbler.
- Yellow-rumped: the classic winter feeder warbler — suet and dried fruit, often in flocks.
- Both join mixed winter flocks with chickadees and kinglets.
- Plant: wax myrtle and bayberry hold yellow-rumps all winter.
Temperament & Flock Behavior
Orange-crowned Warblers are methodical gleaners, working low shrubs at a measured pace.
Yellow-rumped Warblers are restless — flycatching, berry-plucking and chip-calling constantly in winter flocks.
6-Step Backyard ID Checklist
