Cedar waxwings do not follow a single, predictable migration route; instead, they wander nomadically in search of fruit, with movements that vary widely by region and year. While many birds migrate north to breed and south for winter, cedar waxwings are irruptive, meaning their seasonal movements are driven by food availability rather than a fixed calendar.
What Makes Cedar Waxwing Migration Unusual
Most songbirds migrate between a specific breeding ground and wintering ground, but cedar waxwings break that pattern. They are frugivores—fruit eaters—and their entire year revolves around finding berries. Because fruit crops vary from year to year and place to place, waxwings move in flocks to wherever the food is. This behavior is called irruption, and it means their presence in any given area can be unpredictable.
In a typical year, cedar waxwings breed across southern Canada and the northern United States, then move south for winter, reaching as far as Central America. However, in years when berry crops are abundant in the north, some birds may stay far north all winter. Conversely, in years of poor fruit production, large flocks may irrupt far south of their usual range. These movements are not random—they are a direct response to where fruit is available.
Breeding and Wintering Ranges
Cedar waxwings breed in open woodlands, orchards, and suburban areas across most of the United States and southern Canada. Their breeding range stretches from British Columbia east to Newfoundland, and south through the northern half of the U.S. In winter, they withdraw from the northernmost parts of their range, but some remain as far north as the Great Lakes and New England if food is plentiful.
The winter range extends south to the Gulf Coast, Mexico, and Central America. In the Pacific Northwest, waxwings are present year-round, as are those in the Appalachian region. The key factor is not temperature but the availability of fruit—if berries persist through winter, the birds will stay.
How Food Drives Their Movements
Cedar waxwings rely on a diet that is almost entirely fruit, especially in winter. They eat berries from junipers, mountain ash, dogwood, and many ornamental shrubs. Because these fruits are often abundant in one area and absent in another, waxwings move frequently, sometimes covering hundreds of miles in a single season.
In late summer and fall, they shift from insects to fruit, building up fat reserves for migration. Their nomadic wanderings are not a single journey but a series of local movements as they follow ripening fruit. This is why you might see a flock in your yard for a few days, then not again for months—they are moving on to the next berry supply.
Timing of Migration
Unlike many birds that migrate on a strict schedule, cedar waxwings have flexible timing. In spring, they typically move north between March and May, arriving on breeding grounds when insects and early berries are available. In fall, they move south between September and November, but some linger until December.
In the southern parts of their range, waxwings may not migrate at all. In the north, they are among the last migrants to leave, often waiting until cold weather forces them to move. Their migration is also influenced by the fruiting times of native plants, so in years when berries ripen late, the birds may delay their journey.
How to Observe Cedar Waxwing Migration
To see cedar waxwings, look for flocks in areas with abundant fruit. During migration, they often stop in parks, orchards, and residential neighborhoods with berry-producing trees. They are social birds, so you are more likely to see a group than a single bird.
- Plant native berry-producing shrubs like serviceberry, dogwood, and elderberry to attract them.
- Look for them near fruiting trees in late afternoon, when they are most active.
- Listen for their high-pitched, trilling calls, which are often the first clue they are nearby.
- Watch for their distinctive yellow tail tips and black mask, which make them easy to identify.
Common Misconceptions
One common misconception is that cedar waxwings migrate in a straight line from north to south. In reality, their movements are erratic and can include east-west shifts. Another myth is that they are strictly migratory; in fact, many populations are resident, especially in milder climates.
People also often confuse cedar waxwings with Bohemian waxwings, a larger, more northern species. Cedar waxwings have yellow bellies, while Bohemian waxwings have gray bellies and rusty undertail coverts. Understanding these differences helps birders accurately track their movements.
Conservation and Threats
Cedar waxwings are not considered threatened, but they face challenges from habitat loss and pesticide use. Because they eat fruit, they are vulnerable to ingesting pesticides sprayed on crops and ornamental plants. They also collide with windows, especially when flying in flocks.
Climate change is altering the fruiting times of plants, which could disrupt the waxwings’ food supply. However, their flexible behavior may help them adapt. Conservation efforts focus on preserving native fruit-bearing plants and reducing pesticide use.
Frequently Asked Questions
Do cedar waxwings migrate at night?
Yes, cedar waxwings are primarily nocturnal migrants, like many songbirds. They fly at night to avoid predators and use the cooler air to conserve energy. During the day, they rest and feed on fruit.
How far do cedar waxwings migrate?
Migration distances vary greatly. Some birds move only a few hundred miles, while others travel from Canada to Central America, a journey of over 2,000 miles. The distance depends on where they breed and where food is available in winter.
Why do cedar waxwings sometimes appear in large flocks?
Cedar waxwings are highly social and travel in flocks that can number in the hundreds or even thousands. Flocking helps them find food more efficiently and provides safety from predators. During migration, these flocks can be spectacular to watch.
Are cedar waxwings year-round residents anywhere?
Yes, cedar waxwings are year-round residents in parts of the Pacific Northwest, the northeastern U.S., and the Appalachian region, as long as fruit is available. In these areas, they may not migrate at all.
What is the difference between cedar and Bohemian waxwings?
Bohemian waxwings are larger, have gray underparts, and a rusty patch under their tails. Cedar waxwings have yellow bellies and white undertail coverts. Bohemian waxwings breed in the far north and are less common in the U.S., while cedar waxwings are widespread.
