The Beautiful Cedar Waxwing

The Cedar Waxwing, also known as Bombycilla cedrorum, is a true gem among birds. Its small size, sleek body, and elegant appearance make it a sight to behold. With its beautiful shades of brown and gray feathers, highlighted by a bright yellow belly and a distinctive black mask trimmed in white, the Cedar Waxwing stands out with its unparalleled beauty. The dark shading under its bill accentuates its facial features, giving it an air of refined charm. But it's not just its appearance that makes the Cedar Waxwing special; it's also its unique behaviors and adaptations.

The Unique Characteristics of the Cedar Waxwing

The Cedar Waxwing possesses several distinct characteristics that set it apart from other birds. Firstly, its thin, high-pitched whistles and trills serve as its identification marks, letting observers know of its presence. These vocalizations often lead bird enthusiasts on a delightful chase, as the Cedar Waxwing is usually found high up in the trees. Its sociable nature means that where there's one, there are usually others nearby.

The scientific name of the Cedar Waxwing, Bombycilla cedrorum, loosely translates to "silk-tailed and of the cedars." It belongs to the family Bombycillidae, which includes two other species: the Bohemian Waxwing and the Japanese Waxwing. While both the Cedar and Bohemian Waxwings inhabit North America, the latter is more widespread in the northern latitudes of North America, Europe, and Asia. The Cedar Waxwing, on the other hand, mainly stays in North and Central America.

The Mystery of the Red Wax Tips

One of the most intriguing features of the Cedar Waxwing is its red wax tips on the secondary flight feathers, which give rise to its name. While the presence of these waxy appendages is certain, their purpose remains shrouded in mystery. When a new feather is growing, these waxy tips, made of a carotenoid pigment known as astaxanthin, provide them with their vibrant red coloring. Interestingly, the number of wax tips varies with age, with mature birds having more appendages than juveniles.

Researchers have proposed various theories regarding the purpose of the red wax tips, but consensus is yet to be reached. One study suggests that birds with more wax appendages nest earlier and raise more offspring, indicating their possible role in attracting a mate. However, further research is needed to fully understand the significance of these enigmatic plumage features.

Habitat and Diet of the Cedar Waxwing

The Cedar Waxwing can be found in a variety of habitats, but two key factors influence its presence: the availability of fruiting trees or shrubs and proximity to a body of water, such as a pond, stream, wetland, or riparian area. While they can occasionally be found in open fields or orchards, their preference is for areas with an abundance of light. Forest interiors are not an ideal habitat for Cedar Waxwings, as the lack of sunlight impedes the growth of fruiting plants they depend on.

When it comes to diet, the Cedar Waxwing is a true frugivore, meaning it primarily feeds on fruit. It is especially reliant on berries and consumes a wide array of them, including serviceberry, strawberry, mulberry, dogwood, raspberries, mountain ash, mistletoe, madrone, juniper, honeysuckle, crabapple, winterberry, and Russian olive fruits. Interestingly, their consumption of cedar berries during the winter lends them their name.

The mutualistic relationship between Cedar Waxwings and fruiting plants is truly remarkable. As the birds consume the berries, they pass the seeds through their digestive system, effectively dispersing them far and wide. This benefits the plants by enabling seed distribution and ensuring their survival. It's a perfect example of nature's intricate interdependence.

Despite their fruit-based diet, Cedar Waxwings also supplement their nutrition with protein-rich insects. They catch these insects on the wing or pluck them directly from vegetation. Mayflies, dragonflies, stoneflies, ants, scale insects, spruce budworm, and beetles are among their preferred insect prey. Additionally, they obtain protein from the pollen found in catkins and flowers.

In the spring, Cedar Waxwings exhibit an interesting behavior where they hang from a branch of a maple tree to feed on suspended drops of sap. These drops are created when frozen water causes small cracks to form in branches, leading to the release of sap. The waxwings eagerly lap up this extra source of nutrition.

The consumption of fermented berries, such as overripe ones, can lead to inebriated behavior or even death in Cedar Waxwings. This phenomenon has been observed when waxwings feast on berries that have naturally fermented, producing alcohol content in the fruit.

Mutualistic Relationship with Fruiting Plants

The Cedar Waxwing plays a vital role in the dispersal of fruiting plants by acting as a seed courier. As the birds feed on berries, the seeds pass through their digestive system unharmed, facilitating their transportation to new locations. This mutually beneficial relationship allows both the Cedar Waxwing and the fruiting plants to thrive.

When Cedar Waxwings follow the fruits, they aid in seed dispersal over vast distances. By spreading the seeds through their feces, they contribute to the establishment of new plants and the genetic diversity of fruiting species. In return, the birds have a reliable food source, ensuring their survival and continued presence in ecosystems.

This mutualistic relationship has been particularly significant in the case of Cedar Waxwings and cedar berries. The birds exhibit a strong affinity for cedar berries during the winter months when other food sources may be scarce. By consuming and dispersing the seeds of cedar trees, the waxwings contribute to the perpetuation of these important tree species.

Other Food Sources for the Cedar Waxwing

While fruit constitutes the majority of their diet, Cedar Waxwings also rely on protein-rich insects for sustenance, especially during the warmer months. They catch insects on the wing or pluck them off vegetation, satisfying their need for vital nutrients.

Mayflies, dragonflies, stoneflies, ants, scale insects, spruce budworm, and beetles are among the insects that make up a significant portion of the Cedar Waxwing's diet. The abundance of insect protein helps support their growth and development and provides them with essential nutrients needed for breeding and raising young.

In addition to insects, Cedar Waxwings also obtain protein from pollen. They extract pollen from catkins and flowers, ensuring a diverse diet that meets their nutritional requirements. This adaptability allows them to thrive in various environments and take advantage of available food sources.

Interesting Behaviors and Adaptations

Cedar Waxwings exhibit fascinating behaviors and adaptations that contribute to their survival and success. One such behavior, observed during the spring, involves hanging from a branch of a maple tree to feed on suspended drops of sap. These drops form when frozen water causes small cracks in the branches, creating an opportunity for the waxwings to access this additional food source.

Another intriguing aspect of Cedar Waxwings is their nomadic nature. Rather than following a strict migratory pattern, they move based on the availability of fruiting crops. This irregular movement allows them to adapt to changing food sources and maximize their chances of finding abundant fruit supplies. Their ability to form large flocks further aids in locating and exploiting new food resources.

Cedar Waxwings are known for their distinctive hopping and passing behavior during courtship rituals. The male initiates the courtship by performing a hopping dance in front of a female. If she is interested, she will hop back, and the male will approach her with a gift, such as a berry, flower, or insect. The female will accept the gift and then hop away before hopping back and passing the item back to the male. This ritual continues until the female accepts the gift and consumes it. This elaborate display of courtship highlights the bonding and communication that takes place between mates.

Breeding and Nesting Habits

Cedar Waxwings are monogamous for a single breeding season, during which they seek out suitable nest locations together. They look for a fork on a horizontal branch, typically situated around 6 to 20 feet above the ground. While both the male and female participate in the search, it is the female who ultimately selects the nesting site.

The nest construction process is a joint effort, with both the male and female contributing materials. The female takes charge of the construction, weaving twigs, grasses, cattail down, cottonwood fluff, string, or horsehair into a bulky cup. Soft materials are then added to provide the nest with a comfortable lining. The construction process takes around five to six days and involves an impressive 2500 individual trips to gather suitable materials.

Interestingly, Cedar Waxwings have been known to steal nest materials from nearby nests, such as those belonging to Eastern Kingbirds, Robins, Orioles, Yellow Warblers, or Yellow-throated Vireos. This behavior allows them to save time and effort by utilizing existing resources to complete their nests.

Cedar Waxwings typically have one to two broods per breeding season, and each brood consists of two to six eggs. The eggs are pale blue or whitish gray, adorned with black and brown speckles. Nesting is often timed to coincide with the availability of fruiting trees, ensuring a plentiful food supply for the growing chicks.

During the first few days of life, the nestlings are primarily fed insects, which provide essential protein for their rapid growth. As they mature, the ratio of insects to fruit gradually shifts, with the chicks consuming more fruit as they develop. This dietary transition prepares them for their eventual transition to an exclusively fruit-based diet.

It's worth noting that Cedar Waxwings are not territorial and can nest in fairly close proximity to one another. On occasion, multiple nests have been observed within a short distance, highlighting their high tolerance for nesting neighbors.

Migration Patterns of the Cedar Waxwing

Cedar Waxwings are classified as short to long-distance migrants. However, their movements are more accurately described as nomadic, as they often travel irregularly in response to the availability of fruiting trees and shrubs. These resource-driven migrations result in breeding populations as far north as Northern Canada and wintering populations as far south as Costa Rica and Panama.

The precise extent of their migrations can vary from year to year, as their movements depend on the fruiting crop in a given area. In years where food is abundant in their breeding range, Cedar Waxwings may remain there for the winter. Conversely, if food becomes scarce, they may venture further south in search of favorable feeding grounds.

The ability of Cedar Waxwings to adapt their movements to changing food sources and make use of diverse habitats is a testament to their flexibility and resilience. It also adds an element of unpredictability to their presence in different regions, making them a fascinating subject of study for bird enthusiasts.
