Wonders Of The Waxwings - Cedar And Bohemian Waxwings


Cedar Waxwings
Bohemian Waxwings

"Forehead Up" is a Native American name for waxwings. I think that's because D.A. was already taken.

 
A group of waxwings are collectively known as an "ear-full" and a "museum" of waxwings
Seidenschwänze (Silky Tails) is what they are called in Germany.

     In the past three days, I have had two 'lifer' birds. "Life" or "Life Birds" are what birders call birds that they have seen for the first time. Each one of these gets added to a birder's "life list." Some say that the numbers on a life list are what separate the men from the boys of birding. There are "bird watchers" and "birders." "Bird watchers" are those who enjoy the birds but don't bother to learn to identify them. Some bird watchers live to merely tick birds off a list, thus building the list. "Birders" are those more interested in birding behavior, habitats and conservation. They are exacting in their identifications. "Birders" generally regard "Bird Watchers" with disdain, or at the very least, the begrudging tolerance one might bestow upon a snivelling younger sibling.  I fall somewhere in between. My Life List is pretty short by most standards (Like my weight, I'm not going to say what it is), because I'm fairly new to birding. Common birds may nonetheless be new birds for me. The longer a birder has been adding to their list, the harder it gets to add new birds. 
     I got my new lifers while racing back and forth to a nursing home to be with my grandmother. She is 100 years old; she has a long, rich life list. For the past four days, she has been trying to die without success. My husband says she's holding on because she is angry about the change in her astrological sign and is conducting a resistance demonstration. He, she and I are all, or at least were, Aries and proud of it.
     I've gone every day to sit with her. She is in and out of a coma, refusing all fluids and sustenance. Her lungs are filling as her old heart is slowly giving out. I'm not sure she even knows I'm there. Once in a while, she opens her eyes, but clearly sees nothing. When I stand up to stretch my howling back, she does clutch, as if fearing that I'm going to leave. It may be my imagination. We are just sitting, waiting. While she has been having her last life experiences, I've been racking up life firsts in birds, which gives me solace.
     On one of my trips to the nursing home, I saw my first Bohemian waxwings. There was a flock of 126 of them, a pretty good showing for a life first! The following day, I saw a second flock in the parking lot of the nursing home. Waxwings are gregarious, aggressive birds and very vocal. A flock or group of them is called an "ear-full."  Waxwings are characterised by soft silky plumage. Because of this, it's tricky to get feather detail in  photographs. They have unique red tips to some of the wing feathers where the shafts extend beyond the barbs. These tips look like sealing wax, and give the group its common name. When I was a teenager, I was a prolific letter writer. I enjoyed the whole process, including closing the flap with a dollop of hot, red wax and applying my seal to it. I still have my 'R' stamp, if not my astrological sign.
    Male and Female waxwings have the same mainly brown plumage, a black line through the eye and black under the chin, a square-ended tail with a red or yellow tip, and a pointed crest. The bill, eyes, and feet are dark. One of the quickest ways to tell the difference between Cedar waxwings and Bohemian waxwings is the underside, or "coverts" of the tail. As seen in the photos above, the Bohemian has a distinctly rusty red underside, where the Cedar does not. If the sun is shining, this feature is plainly seen even at a distance or on a bird in flight. 
     In North America there are only two species of waxwings. The Cedar waxwing is the more common, but is found only in this continent, while the Bohemian waxwing  is more rare in this hemisphere. It's a bird of northern latitudes. There is a third waxwing, the Japanese waxwing. You've probably guessed it's found in Japan. If we ever see them here, it will be because the earth has shifted on its axis again and we'll get a fourteenth zodiac sign.
     Cedar waxwings like cedar and juniper berries, thus the name. Bohemian waxwings are named for their wandering, vagrant ways. We only get these arboreal irruptives here when they push south from  the northern forests in search of food. True Bohemians, they are known for suddenly appearing, then disappearing. As a German immigrant, my grandmother referred to herself as a Bohemian, too. To be as accurate as a true birder, I should say that she was really my first Bohemian.
     All waxwings like fruit, though they eat insects in spring when egg laying and feeding young. During the winter, a birder can expect to find waxwings devouring Crabapples and thickets of Winterberries. There are some color variations in feathers resulting from which fruits the birds eat. Orange, rather than yellow bands sometimes seen on the tails are attributed to pigments found in an alien honeysuckle fruit introduced to their diet. There are several places with Crabapple trees that I visit frequently during the winter hoping for waxwings. Waxwings and berry bushes are closely linked; flocks gather, devour one crop and then, almost mysteriously, disappear to find the next. They pass the seeds right through their systems as they go, making a mess, a behavior belying their gentlemanly appearance. In a day or two, when the fruit is stripped, they vanish - here today, gone tomorrow. I was lucky to have seen the Bohemians. Had my timing differed by mere minutes, I would not have been able to add them to my life list.
     Any day now, my grandmother will disappear like the waxwings, too. Though it hasn't always been tidy with her either, I'm lucky to have known her, to have added her to my life list.
