Yellow-rumped Warbler
Least ConcernSetophaga coronata
Visual Identification
Appearance
The Yellow-rumped Warbler is a medium-sized warbler, notable for its yellow patches on the rump, sides, and crown. The bird has distinctive grey plumage with black streaks on its back and wings, along with white wing bars and tail spots.
Males are more vibrantly colored than females, particularly in breeding season when they display black cheeks and breast patches. During winter, both sexes become more subdued, with brownish-grey upperparts and less prominent yellow markings.
There are two main varieties: the Myrtle Warbler (found in eastern/northern North America) with a white throat, and the Audubon's Warbler (in western North America) with a yellow throat.

Distribution
Yellow-rumped Warblers breed in coniferous and mixed coniferous-deciduous forests across Canada, Alaska, and the northeastern and western United States. During winter, they can be found in a variety of habitats, including open woods, shrublands, and gardens.
In the non-breeding season, they are widespread across the southern United States, Mexico, and Central America. They are common visitors to backyard feeders in many parts of North America, especially during migration and winter.

Distribution Map
This map gives you a rough idea of where you might spot a Yellow-rumped Warbler. The coloured areas show countries where these birds have been seen.
A few things to keep in mind:
- Birds might not be everywhere in the coloured areas, for example, they may be present around the coast of that country
- Where birds live can change with seasons and available food
- This map is quite simple - it doesn't show exact locations
We're working on making our maps even better! Soon, we hope to show you:
- More detailed maps for bigger countries, including state and region
- How birds move around during different seasons

Share your thoughtsBird Attributes Explained
Our bird attributes system rates various aspects of a bird's capabilities on a scale of 0-100, based on data from field observations, scientific studies, and expert knowledge.
Attribute Categories:
- Agility: Manoeuvrability, speed, and grace in flight or movement.
- Strength: Physical power, often correlating with size and hunting abilities.
- Adaptability: Ability to thrive in various environments or changing conditions.
- Aggressiveness: Territorial behaviour and assertiveness, particularly during breeding seasons.
- Endurance: Stamina, often seen in migration patterns or foraging behaviours.
Understanding the Ratings:
- 0-20: Very Low
- 21-40: Low
- 41-60: Average
- 61-80: High
- 81-100: Very High

Agility
Reflects the bird's manoeuvrability, speed, and grace in flight or movement.
Highly agile flycatcher capable of swift aerial manoeuvres, skilled at both catching insects mid-flight and gleaning prey from foliage. Their small size and ability to navigate through dense vegetation whilst foraging demonstrates exceptional manoeuvrability.
Strength
Indicates the bird's physical power, often correlating with size and hunting abilities.
As a small warbler weighing only 12-13g, their physical strength is limited. Whilst capable of carrying nesting materials and feeding young, they're not built for powerful activities, focusing instead on agility and efficiency.
Adaptability
Represents the bird's ability to thrive in various environments or changing conditions.
Remarkably adaptable species, able to digest unique waxes in berries, switch between insect and fruit diets, survive in various habitats from sea level to 4,000m, and thrive across different climate zones. Their success in urban environments and stable population of 170 million further demonstrates this adaptability.
Aggressiveness
Measures the bird's territorial behaviour and assertiveness, particularly during breeding seasons.
Generally peaceful birds that form loose flocks with other species outside breeding season. Whilst they'll defend their nesting territories, they show relatively low aggression compared to other bird species. Their social nature suggests a more cooperative than aggressive disposition.
Endurance
Reflects the bird's stamina, often seen in migration patterns or foraging behaviours.
Strong endurance evidenced by their successful migrations, ability to winter further north than other warblers, and capacity to forage actively throughout the day. Their broad elevation range tolerance and varied habitat usage suggests robust stamina for their size.
Diet
Yellow-rumped Warblers have a varied diet, including insects, spiders, and berries. They are unique among warblers in their ability to digest the waxes found in bayberries and wax myrtles, allowing them to winter farther north than other warbler species.
In summer, they primarily consume insects caught on the wing or gleaned from vegetation.
Behaviour
Yellow-rumped Warblers are agile foragers, often seen flycatching from perches or gleaning insects from foliage. They form loose flocks outside of breeding season, frequently mixing with other small bird species.
These warblers are known for their ability to switch between insect and fruit diets, adapting to seasonal food availability.
Vocalisation
The Yellow-rumped Warbler's song is a series of sweet, whistled trills that rise and fall in pitch. Their call is a distinctive, sharp 'chip' or 'check,' often repeated.
During foraging or in flight, they may give a soft 'tsip' note. In winter, flocks communicate with quiet 'contact' calls to maintain group cohesion.
Nesting & Breeding
Yellow-rumped Warblers typically form monogamous pairs each breeding season, which begins in late spring. Males perform aerial displays and sing to attract mates.
Nests are usually built in coniferous trees, constructed primarily by the female using twigs, grass, and moss, lined with feathers and hair. The female lays 3-5 pale blue-white eggs with brown spots.
Incubation lasts about 12-13 days, carried out mainly by the female. Both parents feed the nestlings, which fledge after 10-14 days. Pairs often raise two broods per season in the southern parts of their range.
Lifespan
The Yellow-rumped Warbler typically lives for 6 to 8 years, with a maximum recorded lifespan of 10 years.
Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.
Conservation and Status
Global Conservation Status
Yellow-rumped Warblers are currently of least concern due to their large range and stable population. However, they face threats from habitat loss and climate change.
Conservation efforts focus on protecting breeding and wintering habitats, including boreal forests and coastal areas.
Birdwatching Tips
- Look for flashes of yellow on the rump as the bird flies or hops between branches
- Listen for their distinctive 'chip' call, which is often repeated
- Check berry-producing shrubs in fall and winter, where these warblers often feed
- In the US and Canada, watch for them in mixed flocks during migration
