Cedar Waxwings are a favorite of many birders and backyard naturalists. With their fuzzy-looking crests and sharp color accents, they’re dapper looking birds. A large flock of them picking through berries is always entertaining to watch. I count myself a member of the Waxwing Fan Club.
But what’s in a name? Why is it called a waxwing?
That’s pretty simple: Cedar Waxwings really have wax wings. The bright red, visible on the wing feathers of some waxwings, is actually waxy red secretions.
What’s the purpose of the wax? That question seems more difficult to answer. Many ornithological sites state that the purpose remains unclear.
Dave Mehlman, director of The Nature Conservancy’s Migratory Bird Program, often fields questions about various bird species. The Migratory Bird Program works to identify networks of habitat needed by bird species throughout North America, Latin America and the Caribbean. Then, they develop plans and implement strategies to help conserve them at the local level.
Recently, Mehlman was asked about the purpose of those wax wings. He shared what he found with me:
The red wax tips are appendages on the bird’s secondary feathers. They’re colored by astaxanthin, a carotenoid pigment.
While it was originally thought that the red tips functioned to protect the feathers from wear and tear, there is little to no evidence for this hypothesis.
Rather, red secondary tips appear to be status signals that function in mate selection. Rare individuals have been noted with yellow waxy tips on secondary feathers.
Interestingly, the red appendages of Cedar Waxwings increase in number and size with a bird’s age: individuals with zero to five waxy tips are presumable immature birds, while those with greater than nine are thought to be older.
Individuals within these two categories tend to associate as mates. Pairs of older birds (those with greater than nine waxy tips) nest earlier and raise more young than do immature birds, suggesting that this plumage characteristic is an important signal in mate choice and social organization.
Mehlman says this all suggests that waxwings evolved the red wax secretions as plumage enhancements to signal their age, maturity and social status among waxwings. This is a useful signal in a species that often is found in large flocks.
There is another interesting color phenomenon among Cedar Waxwings. These birds also have a striking yellow tail tip, but in some parts of their range some birds began appearing with orange tail tips in the 1960s.
According to the Cornell Lab of Ornithology:
The orange color is the result of a red pigment picked up from the berries of an introduced species of honeysuckle. If a waxwing eats enough of the berries while it is growing a tail feather, the tip of the feather will be orange.
And about those berries: Cedar Waxwings specialize in eating fruit, an interesting adaptation among North American birds. While we think of many birds as dining on berries, in reality berries are only ever a portion of their diets. Cedar Waxwings can exist solely on berries for months.
In fact, when that well-known nest parasite the Brown-headed Cowbird lays its egg in a Cedar Waxwing nest, the young cowbird has difficulty surviving. The high fruit diet is not conducive to a young cowbird’s growth and prosperity.
Sometimes, Cedar Waxwings eat berries that have fermented on the vine, leading to inebriated behavior from the birds.
Come summer, waxwings are often seen hunting insects. In fact, when I’m fly fishing a heavy mayfly hatch, I’ll often see them snatching the small insects as they hover over the water.
Even our common backyard birds are full of surprises. Enjoy their antics, and remember that your observations can often contribute to bird research and conservation.
That is so amazing to see the design of these birds serving an important purpose. Evolution clearly cannot explain this as it has no means of determining one thing to be advantageous over another. The Creator purposely designing this into the bird kind makes far more sense of what we observe, and the science certainly agrees.
Excellent comments on the red “wax” of the Cedar Waxwing. Now I know how the name waxwing came to be. Cedar was easier for I often see them amidst the cedars feeding during Michigan winters.
Why is cedar part of its name?
Wax Wings are in my Bing and Back Tartarian cherries early this year. I rarely get to eat my cherries, but the shade the trees provide, and the bird entertainment is worth a lot. The waxwings are even quicker than hummingbirds in moving from place to place.
I recently had a flock on our backyard tree and was able to take several great photos. I live in the GTA of Ontario. I would share my photos but can’t seem to be able too.
I spotted a museum of cedar waxwings in a pyrocantha tree several years ago in Southwest Houston. They were passing the red berries beak-to beak down the row of birds. When the one at the end had eaten all the berries, it would fly away. Then the next bird in the row would move into the vacated position, making that bird the recipient of the berries. This process was repeated until the last bird had eaten it’s fill and flown off to join the others. As I recall the whole process was quite noisy!
I saw these beautiful birds this November morning eating some blue colored berries off a bush on our yard. I described the bird and google was able to tell me the name, with pictures. My cats were having a great time watching their antics.
I was very grateful to see these birds and to find out their name.
I find them VERY beautiful.
Great article! I just found a young waxwing dead in my yard and it had bright orange tail tips. That led me to this article, as I’ve never seen one with orange tail tips. They are a favorite, and I’ve planted a couple of crabapples and viburnums to hopefully increase my sightings of them.
We just noticed a pair of cedar wax wings building a nest in a tall pine tree in our Eastford CT backyard. We’ll keep watch.
Wondering how the nesting went?
Thank you for your article. I took a picture of two cedar waxwings and two mountain bluebirds together in a juniper behind my house. Didn’t notice until late that I could see the red tips on one o the waxwings. Hadn’t noticed that before in any other pics I have of them.
Have you ever seen a waxwing store berries in feathers around wing area?
We rescued a couple of these birds after they got drunk and flew into our building.
Both had berries stuffed in their feathers.
That was very helpful information. I am again fly fishing the CT River way north in Pittsburg, NH, watching the waxwings weaving above the river to catch in mid-air whatever has just hatched from the water below. It surprises me that they seem the only birds to be doing this. Beautiful angels of death for insects only allowed a second of life.
I have a waxing in my back garden, and a Jay. Both beautiful birds. I spotted the Waxing last May, and it was a lovely pinky clolour. Today it is the Jay, quite a big bird very stunning. For we have quite a few fruit bushes growing their berries, and a cherry tree in the next garden
Love seeing them
We had a cedar waxwing this winter that would take 1 peanut (from a handful thrown out for blue jays) every morning. If we forgot to put them out, s/he would wait patiently on the deck.
