About the Cedar Waxwing
The Cedar Waxwing, Bombycilla cedrorum, is a striking bird with a unique appearance that captivates bird enthusiasts and casual observers alike. Belonging to the family Bombycillidae, this species plays a significant ecological role by dispersing seeds and controlling insect populations. Found primarily in North America, the Cedar Waxwing thrives in open woodlands, orchards, and urban areas where fruiting trees abound. These birds are particularly fond of cedar berries, which contribute to their name. Cedar Waxwings are social birds, often seen in flocks outside the breeding season, and their gregarious nature makes them a common sight in suitable habitats.
The bird's ecological significance cannot be overstated. By consuming large quantities of fruit, Cedar Waxwings help disperse seeds across their range, promoting plant diversity and forest regeneration. They also consume a variety of insects, providing natural pest control vital for healthy ecosystems. These birds are known for their nomadic tendencies, moving unpredictably in search of abundant food sources, especially during fall and winter.
Seasonal behaviors of Cedar Waxwings include migratory movements, though they are not long-distance migrants like some other species. They breed across southern Canada and the northern United States and winter further south, extending into Central America. During spring and summer, they engage in elaborate courtship displays, which include passing berries between mates. Breeding pairs raise their young in nests constructed in trees or shrubs, often close to water sources. The presence of Cedar Waxwings indicates a healthy environment rich in fruit-bearing plants and insect life.
The Cedar Waxwing belongs to the family Bombycillidae, within the order Passeriformes. These birds typically live average 7 years with some living up to 10 years.
How to Identify a Cedar Waxwing
Cedar Waxwings are medium-sized songbirds measuring about 6 to 7 inches in length with a wingspan of approximately 9 to 12 inches. Their sleek, silky plumage is a key identifying feature, with a soft brown head and crest, gray wings, and a pale yellow belly. The name 'waxwing' derives from the small, red, waxy tips on their secondary wing feathers, a trait shared with the closely related Bohemian Waxwing. Both adults and juveniles exhibit similar coloration, though juveniles have streaked underparts and less vibrant wing tips.
Males and females are similar in appearance, making visual sex differentiation challenging. However, during courtship, males often display their distinctive crest more prominently. Cedar Waxwings can be distinguished from similar species like the Bohemian Waxwing by their smaller size and the absence of white and yellow wing markings found on the latter.
In flight, Cedar Waxwings exhibit a sleek silhouette with pointed wings and a short tail accented by a bright yellow band. When perched, their erect posture and tidy crest are distinctive. Their sociable nature often leads them to be observed in flocks, especially when feeding on fruiting trees.

Cedar Waxwing Habitat and Range
Preferred Habitat
Cedar Waxwings inhabit a wide range of environments, from deciduous and mixed woodlands to urban parks and gardens. They are especially drawn to areas with abundant fruiting trees such as those found in orchards and along forest edges. In the breeding season, they prefer habitats near water sources, which provide both food and nesting opportunities.
While they are primarily associated with lowland areas, Cedar Waxwings can also be found at varying elevations up to 3,000 meters, especially in the northern parts of their range. Seasonal shifts in habitat occur as these birds move southward in winter, where they frequent open areas and suburban settings offering plentiful fruit and shelter.
Urban presence is notable, as Cedar Waxwings often visit backyard gardens with fruiting shrubs and trees. Their adaptability to both rural and urban environments makes them a widespread and common sight across their range, particularly during migration and in winter.
Geographic Range
The Cedar Waxwing's breeding range stretches across southern Canada and the northern United States, from the Pacific coast to the Atlantic. They are less common in the southeastern United States during the breeding season, where suitable habitats are more fragmented. In winter, their range extends further south through the United States and into Central America, reaching as far south as Panama.
Migration corridors for Cedar Waxwings are less defined than for some other species, as their movements are largely driven by food availability rather than strict migratory paths. Key regions where they concentrate include the Great Lakes area and the northeastern United States during fall, where they feast on abundant autumn berries. The birds' population density hotspots align with areas rich in fruit-bearing trees, making them more visible in places like the Pacific Northwest and along the Mississippi River Valley.
During spring and summer, Cedar Waxwings may be found throughout their breeding range, while in winter, they become more common in southern states like Texas and Florida, as well as in parts of Mexico and Central America.

What Does the Cedar Waxwing Eat?
The Cedar Waxwing's diet consists primarily of fruits and berries, with a preference for those from trees such as cedar, juniper, and hawthorn. During the breeding season, they expand their diet to include insects like beetles, caterpillars, and ants, which provide necessary protein for growing chicks. As fall approaches, Cedar Waxwings shift their focus back to fruit, often seen ravaging berry-laden shrubs in large flocks.
Their foraging technique involves methodically stripping trees and bushes of their fruit, often swallowing berries whole. The waxwing's ability to handle large quantities of fruit is aided by their specialized digestive system, which processes fruit rapidly, allowing them to consume significant amounts in a short time.
While primarily diurnal feeders, Cedar Waxwings are most active in the morning and late afternoon, when they can be seen flitting between feeding sites. Their reliance on fruit makes them vulnerable to periods of scarcity, prompting unpredictable movements in search of food.
Cedar Waxwing Behavior and Social Structure
Cedar Waxwings are highly social birds, often observed in flocks throughout the year. Outside the breeding season, they form large, loose groups that forage and travel together in search of food. These flocks can number in the dozens or even hundreds, creating a lively spectacle in fruiting trees.
Territorial behavior is minimal among Cedar Waxwings, with pairs establishing only small territories around their nest during the breeding season. Courtship displays are an elegant affair, involving the exchange of small objects like berries or twigs between potential mates. This ritual strengthens pair bonds and leads to cooperative nesting efforts.
Cedar Waxwings respond to predators, such as hawks and owls, with swift, coordinated flight, often seeking refuge in dense foliage. Their daily activity patterns revolve around feeding and socializing, with a distinct peak during cooler parts of the day. These birds are mostly active during daylight hours, though they may continue feeding in low light when food is abundant.
Cedar Waxwing Nesting and Reproduction
Cedar Waxwings construct cup-shaped nests using grass, twigs, and other plant materials, often lined with softer substances like feathers or moss. Preferred nest sites include forks of tree branches, typically at heights ranging from 3 to 15 meters above the ground. Trees near water sources are favored, as they provide both abundant food and concealment from predators.
The typical clutch size for Cedar Waxwings consists of 3 to 5 eggs, which are pale gray-blue with black spots. Both parents share incubation duties, which last about 12 to 14 days. After hatching, the young are fed by both adults, who bring a mix of insects and partially digested fruit to the nest. Fledging occurs approximately 14 to 18 days post-hatching, with the fledglings remaining dependent on parental care for several weeks.
Cedar Waxwings may raise two broods per year, particularly in regions where food resources are plentiful. This reproductive strategy ensures that they can exploit favorable conditions to maximize their offspring's survival.
Cedar Waxwing Sounds and Vocalizations
The Cedar Waxwing's primary song consists of high-pitched, trilled notes that often form a delicate, sibilant chorus. Their calls include a series of thin, high-pitched whistles that can sound like a gentle hiss. These sounds are most often heard when the birds are in flocks, communicating as they forage or travel.
During the dawn chorus, Cedar Waxwings contribute their soft, twittering notes, blending into the background of other bird songs rather than dominating the soundscape. Their alarm calls are similar in pitch but slightly more abrupt, serving as a warning to other flock members of potential threats.
The Cedar Waxwing's vocalizations lack the complexity of some other songbirds, yet their subtlety and sweetness are distinctive among North American avifauna.
