Orange-Crowned Warbler vs Tennessee Warbler

Orange-Crowned Warbler

Leiothlypis celata

How to recognise an orange-crowned warbler?

General appearance

The orange-crowned warbler is a small songbird with an inconspicuous orange patch on the crown, often hidden and rarely visible. Its plumage is generally olive-green with a yellowish undertone. The underparts are paler with a duller yellow, and the bird typically exhibits an indistinct eyeline and a faint wing bar. Its compact body and thin, pointed bill are distinctive physical traits. Observers might note its slight flicking tail movements.

Male vs female

Males and females are similar in appearance, both sporting the same overall color scheme. However, males may sometimes possess a more vivid yellow underbelly than females. The orange crown is typically less prominent in females. Both sexes share olive-brown upperparts and a lack of prominent wing bars.

Juvenile

Juvenile orange-crowned warblers resemble adults but with duller plumage. Their yellowish underparts and olive hues are less pronounced, appearing more grayish. Juveniles also lack the subtle orange crown, which only becomes visible as they mature. In the wild, they may be identified by their subtler color and less energetic behavior.

Size

4.3 - 5.5 in/0.3 - 0.4 oz

Habitat

Primary habitat

The orange-crowned warbler prefers shrubby vegetation, specifically deciduous undergrowth in habitats like spruce and fir-aspen forests, streamside thickets, and chaparral with partly shaded ground.

Additional range

During migration and winter, it uses brushy tangles in similar habitats, and can also be found in gardens and parks.

What do orange-crowned warblers like to eat?

Natural diet

The orange-crowned warbler primarily consumes insects, with a particular focus on insect larvae during the summer months when feeding nestlings. In the winter, this bird's diet shifts as it feeds on the sap from wells drilled in tree bark by sapsuckers or other woodpeckers. On its tropical wintering grounds, its diet is more varied and includes insects, nectar, and berries.

Bird feeders

At bird feeders, the orange-crowned warbler is known to consume suet and peanut butter, making these common sources of nutrition when natural food is less available.

What does an orange-crowned warbler sound like?

The orange-crowned warbler's vocalizations are distinct but simple. Its song is a delicate trill that ascends or descends the scale, notably toward the end. The call is a sharp 'stik', reflecting its crisp, short sound. The pattern of the call tends to fall, with a flat, chirp or chip-like quality. Some also describe the call or song as a 'hi, trill', suggesting a higher, more extended trill sound. Thus, this little bird presents a melodious blend of rising or falling trills alongside sharper, concise call notes.

Tennessee Warbler

Leiothlypis peregrina

How to recognise a Tennessee warbler?

General appearance

The Tennessee warbler (Leiothlypis peregrina) is a small songbird with a wingspan of about 8.5 inches. It features an olive-green back, gray to whitish underparts, and a pale eyebrow stripe. The wings are relatively plain with no wing bars. It has a sharp, short bill ideal for feeding on insects and nectar.

Male vs female

Males and females are visually similar, but males may exhibit slightly brighter olive-green coloration, especially during the breeding season. Both sexes display the characteristic pale eyebrow and lack distinct markings on their wings, making them challenging to differentiate.

Juvenile

Juvenile Tennessee warblers look similar to adults but tend to have a duller overall coloration. Their underparts may appear slightly buffy, and their plumage lacks the bright luster of adult birds. These differences lessen as the bird matures.

Size

3.9 - 5.1 in/0.3 - 0.4 oz

Habitat

Primary habitat

The Tennessee warbler's primary habitats are deciduous and mixed forests, especially balsam-tamarack bogs, aspen and pine woods, or edges of dense spruce forest. It nests near boggy ground depressions.

Additional range

During migrations, the warbler is found in groves and brush. In spring, it tends to be high up in trees, while during fall it can be found lower in saplings, brush, and weedy fields.

Range Map

What do Tennessee warblers like to eat?

Natural diet

The Tennessee warbler primarily feeds on insects, with a preference for caterpillars, scale insects, aphids, beetles, flies, ants, leafhoppers, and spiders. During the summer, insects form the bulk of its diet. It also consumes nectar from catkins and juice from grapes. In the winter, while in tropical regions, its diet includes nectar, berries, and protein-rich structures produced by cecropia trees at the base of leaves.

Bird feeders

Typically, Tennessee warblers are not regular visitors to bird feeders. However, they might occasionally be attracted to feeders offering nectar or fruits suited to their preference for such natural food sources.

What does a Tennessee warbler sound like?

The Tennessee warbler possesses a unique vocalization, traditionally broken into three distinct parts. It often starts with a sharp, staccato "di-dit-di-dit" followed by a "swit-swit-swit" sound and concludes with a rapid "chip-chip-chip-chip-chip". Each segment progressively grows faster, culminating in the final flurry of 'chip' notes. The bird's calls encompass varied patterns, from flat singing to chirp or chip-like sounds, pleasant 'hi' notes to trilling songs and even whistles.

How to tell the Orange-Crowned Warbler from the Tennessee Warbler

Visual differences

The Orange-Crowned Warbler (4.3–5.5 inches, 0.3–0.4 ounces) displays olive-green plumage with yellow undertones and a faint orange crown, often hidden. It has a thin, pointed bill, indistinct eyeline, and faint wing bar. In contrast, the Tennessee Warbler (3.9–5.1 inches, 0.3–0.4 ounces) features an olive-green back, grayish underparts, a distinctive pale eyebrow, and lacks wing bars. Its bill is sharp and short. Both species are similar in size and coloration, but the Tennessee Warbler's eyebrow stripe and overall lack of yellowish hues distinguish it.

Key differences and behavior

Orange-Crowned Warblers and Tennessee Warblers exhibit notable behavioral differences. Orange-Crowned Warblers prefer shrubby, deciduous habitats and nest on the ground, with males returning early to defend territories through song. Their diet includes insects and nectar, adapting to available food like suet in winter. Conversely, Tennessee Warblers thrive in deciduous and mixed forests, particularly near bogs. Males court females via song and flight displays, with ground or low shrub nesting. Their diet emphasizes caterpillars and nectar, including berries and nectar in tropical winters. While both species consume insects and nectar, Orange-Crowned Warblers frequent feeders more than Tennessee Warblers. Orange-Crowned Warblers establish song neighborhoods, while Tennessee Warblers aren't typical bird feeder visitors despite occasionally being drawn by nectar or fruit offerings.
