How to recognise a black-throated blue warbler?

General appearance

The black-throated blue warbler is approximately 13 cm in size, comparable to a sparrow. Its colors include black, blue, brown, tan, and white. The wing shape is rounded with a notched or square-tipped tail.

Male vs female

There are discernible differences between the genders. The male seems almost entirely black in shadows, with a white belly and a white spot on the wing. The female presents a more plain, dark upper body and buff lower body accompanied by a faint white wing spot and a dark cheek patch.

Juvenile

Younger females can be identified by the faint white wing spot which may not be as prominent as in mature females. Other physical traits and colorations are presumed to follow adult patterns, maturing with age.

Size

4.9 - 5.3 in/0.3 - 0.4 oz

Habitat

Primary habitat

The black-throated blue warbler primarily resides in dense woods with a rich undergrowth of shrubs and vine tangles. Its preferred forest types include maple, birch, beech, hemlock, spruce, and fir.

Additional range

During migration, they prefer shrubby or forested places. In winter, they inhabit dense tropical woods and also utilize man-made environments like fence rows and gardens.

What do black-throated blue warblers like to eat?

Natural diet

The black-throated blue warbler primarily feeds on insects such as caterpillars, moths, and crane flies during the summer season. Spiders also constitute a part of their diet. In winter, their diet remains largely insectivorous, but they include seeds, berries, small fruits, and flower nectar in their diet to adapt to the changing availability of food sources.

Bird feeders

The black-throated blue warbler is known to visit bird feeders, specifically hummingbird feeders, where it consumes sugar water. This behavior suggests its adaptability to human-provided food sources when natural resources are scarce, particularly during colder seasons.

What does a black-throated blue warbler sound like?

The black-throated blue warbler produces a distinctive husky, rising zwee-zwee-zwee song. Its call pattern is flat but also exhibits a rising trajectory. The warbler showcases a variety of call types including a buzz, chirp or chip, a high-pitched tone, and a whistle. These varied vocalizations contribute to its unique sound repertoire.

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.

Range Map

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.

How to tell the Black-Throated Blue Warbler from the Orange-Crowned Warbler

Visual differences

The Black-Throated Blue Warbler (5 inches) is sparrow-sized with distinct male and female plumage. Males are almost entirely black with a white belly and wing spot; females are darker with a buff underside and faint wing spot. The Orange-Crowned Warbler (4.5-5.5 inches) has olive-green plumage with yellowish undersides and an often-hidden orange crown. Both sexes look similar, with a thin, pointed bill and indistinct eyeline, lacking prominent wing bars. The Black-Throated Blue Warbler has a rounded wing shape, while the Orange-Crowned Warbler has a compact body with a slight tail flick.

Key differences and behavior

The Black-Throated Blue Warbler and Orange-Crowned Warbler exhibit distinct behaviors. Black-Throated Blue Warblers prefer dense woods and low shrubs for nesting, often near the ground, while Orange-Crowned Warblers favor ground nests beneath cover like vegetation. Both species consume insects, but the Black-Throated Blue also enjoys tree sap and berries, visiting hummingbird feeders for sugar water, whereas the Orange-Crowned Warbler relies on sap from sapsucker wells and varies its diet with suet and peanut butter. In winter, their diets diversify. Black-Throated Blue Warblers show some polygyny and fidelity, whereas Orange-Crowned males establish and return to territories ahead of females. The former are 5 inches long, and the latter are 4.5-5.5 inches. Both adapt to winter gardens, though their preferred breeding and wintering grounds differ, focusing on dense woods and shrubby areas, respectively.
