Cedar Waxwings begin moving through the DFW Area in mid January during their spring migration. This observation is of a large group of birds that had gathered on a row of small trees just outside my house.
Here is how Wikipedia describes the Cedar Waxwing:
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.
In winter, these birds can be very confident and will come into gardens for berry bushes and trees and to drink from fountains or bird baths.
