Cedar Waxwing

Bombycilla cedrorum

Summary 43

The cedar waxwing (Bombycilla cedrorum) is a member of the family Bombycillidae or waxwing family of passerine birds. It is a medium-sized, mostly brown, gray, and yellow bird named for its wax-like wing tips. It is a native of North and Central America, breeding in open wooded areas in southern Canada and wintering in the southern half of the United States, Central America, and the far northwest of South America. Its diet includes cedar cones, fruit,...

Behavior and ecology 44

Cedar waxwings are sociable, seen in flocks year round. They are non-territorial birds and "will often groom each other." They move from place to place depending on where they can find good sources of berries.

Mating season for this bird begins around the end of spring and runs through late summer. The male will do a "hopping dance" for the female. If she is interested, she'll hop back. During courtship the male and female will sit together and pass small objects back and forth, such as flower petals or an insect. Mating pairs will sometimes rub their beaks together affectionately. The nest is a loose open cup built with grass and twigs, lined with softer materials and supported by a tree branch averaging 2 to 6 m (6.6 to 19.7 ft) above ground but, at times, considerably higher. It takes around five or six days for the female waxwing to build the nest and can take up to 2,500 trips back and forth. Sometimes the female will steal nest material from other species' nests to save time. The outer diameter of the nest is approximately 12 to 16 cm (4.7 to 6.3 in). Usually 5 or 6 eggs are laid and the female incubates them for 11 to 13 days. The eggs are oval shaped with a smooth surface and very little, if any, gloss. The egg shells are of various shades of light or bluish grey with irregular, dark brown spots or greyish-brown splotches. Both parents build the nest and feed the young. Typically, there are one or two broods during the mating season. Young leave the nest about 14 to 18 days after hatching.

Cedar waxwings eat berries and sugary fruit year-round, including dogwood, serviceberry, cedar, juniper, hawthorn, and winterberry, with insects becoming an important part of the diet in the breeding season. Its fondness for the small cones of the eastern redcedar (a kind of juniper) gave this bird its common name. They eat berries whole. They sometimes fly over water to catch insects. The cedar waxwing is sometimes responsible for significant damage to commercial fruit farms and thus can be considered a pest, especially because it feeds in large groups.

When the end of a twig holds a supply of berries that only one bird at a time can reach, members of a flock may line up along the twig and pass berries beak to beak down the line so that each bird gets a chance to eat.

Sometimes, cedar waxwings will eat fruit that is overripe and has begun to ferment, intoxicating the bird.

Conservation status 44

Waxwings are evaluated as Least Concern on the IUCN Red List of Endangered Species. Populations are increasing in their range partly because fields are being allowed to grow into forests and shrublands, and fruiting trees like mountain ash are being planted as landscaping. On the other hand, cedar waxwings do sometimes crash into windows, and get hit by cars while foraging along roadsides.

Description 44

Cedar waxwings are medium-sized birds approximately 6–7 in (15–18 cm) long and weighing roughly 30 g (1.1 oz). Wingspan ranges from 8.7-11.8 in (22-30 cm). They are smaller and browner than their close relative, the Bohemian waxwing (which breeds farther to the north and west). Their markings are a "silky, shiny collection of brown, gray, and lemon-yellow, accented with a subdued crest, rakish black mask, and brilliant-red wax droplets on the wing feathers." These droplets may be the same color as the madrone berries they are known to eat. These birds' most prominent feature is this small cluster of red wax-like droplets on tips of secondary flight feathers on the wings, a feature they share with the Bohemian waxwing (but not the Japanese waxwing). The wings are "broad and pointed, like a starling's." The tail is typically yellow or orange depending on diet. Birds that have fed on berries of introduced Eurasianhoneysuckles while growing tail feathers will have darker orange-tipped tail-feathers. The tail is somewhat short, and square-tipped. Adults have a pale yellow belly. The waxwing's crest often "lies flat and droops over the back of the head." It has a short and wide bill. The waxwing's black mask has a thin white border. Immature birds are streaked on the throat and flanks, and often do not have the black mask of the adults. Males and females look alike.

The flight of waxwings is strong and direct, and the movement of the flock in flight resembles that of a flock of small pale European starlings. Cedar waxwings fly at 40 km/h (25 mph) and fly at an altitude of 610 m (2,000 ft).

Cedar waxwings are also known as the southern waxwing, Canada robin, cedar bird, cherry bird, or recellet.

The oldest observed cedar waxwing was eight years and two months old.

The two common calls of these birds include very high-pitched whistles and buzzy trills about a half second long often represented as see or sree. Its call can also be described as "high, thin, whistles." They call often, especially in flight.

Diet 44

Cedar waxwings eat berries and sugary fruit year-round, including dogwood, serviceberry, cedar, juniper, hawthorn, and winterberry, with insects becoming an important part of the diet in the breeding season. Its fondness for the small cones of the eastern redcedar (a kind of juniper) gave this bird its common name. They eat berries whole. They sometimes fly over water to catch insects. The cedar waxwing is sometimes responsible for significant damage to commercial fruit farms and thus can be considered a pest, especially because it feeds in large groups.

When the end of a twig holds a supply of berries that only one bird at a time can reach, members of a flock may line up along the twig and pass berries beak to beak down the line so that each bird gets a chance to eat.

Sometimes, cedar waxwings will eat fruit that is overripe and has begun to ferment, intoxicating the bird.

Distribution and habitat 44

Preferred habitat consists of trees at the edge of wooded areas, or "open" forests, especially those that provide access to berry sources as well as water. They are frequently seen in fruiting trees. Waxwings are attracted to the sound of running water, and love to bathe in and drink from shallow creeks. In urban or suburban environments, waxwings often favor parkland with well-spaced trees;
golf courses, cemeteries, or other landscaping with well-spaced trees; bushes that provide berries; and a nearby water source such as a fountain or birdbath. Also look for them near farms, orchards, and gardens, particularly ones with fruiting trees or shrubs.

Outside the breeding season, cedar waxwings often feed in large flocks numbering hundreds of birds. This species is nomadic and irruptive, with erratic winter movements, though most of the population migrates farther south into the United States and beyond, sometimes reaching as far as northern South America. They will move in huge numbers if berry supplies are low. Rare vagrants have reached western Europe, and there are two recorded occurrences of cedar waxwing sightings in Great Britain. Individual Bohemian waxwings will occasionally join large winter flocks of cedar waxwings.

Distribution 47

Cedar Waxwings are native to North and Central America, breeding in open wooded areas in southern Canada and wintering in the southern half of the United States, Central America, and the far northwest of South America.

Habitat 47

Cedar Waxwings can be found in woodlands, orchards and gardens as long as there are fruiting trees or shrubs for them to forage in.

Life History 47

Nesting Females build the nests of twigs, grasses and similar material and sometimes take materials from the nests of other birds. Nests are built in the fork of a horizontal branch.

Feeding Cedar Waxwings are primarily fruit eaters. Interestingly, there are one of the few bird species that can survive on only fruit for months at a time. They will also supplement their diet with invertebrates, including those that are caught on the wing.

Migration 47

Cedar Waxwings are migratory and primarily breed in the northern United States and Canada and Winter in the U.S. and Central America.

Where on Campus 47

Cedar Waxwings can be seen primarily in the Fall and Winter on campus in small flocks in the trees in both the interior plazas as well as the perimeter of campus.
