Two Cedar Waxwings materialized above the wildlife park in Northern Virginia and pirouetted into an aerial ballet. They rose and fell, circled high above the lake, then swooped down close to the ground. They pulled all this off in precise formation like two tiny jets on military maneuvers.
And then the real show began. They landed side by side on a branch at the edge of the lake and began an exchange recognizable no matter whether the species is winged, four-footed or two.
The mating dance was on.
The Cedar Waxwing is an elegant bird. It has a black mask, slicked back head feathers, a brilliant touch of red at the wingtips and a yellow bar on its tail. A junta general couldn’t come up with more dazzling regalia.
They are full of energy, captivating and fascinating, says Robert Rice, a veteran scientist with the Smithsonian Migratory Bird Center, who wrote the center’s summary on Cedar Waxwings.
These stylish birds are also gluttons. They can strip a tree of fruit so quickly they become temporarily too weighty to fly. “They can eat so much fruit it ferments in their gut and they go wobbly for a while,” said Rice.
Cedar Waxwings often travel in small groups, and will sweep through a set of trees and scarf up every ripe berry like locusts.
But the other day at Huntley Meadows Park in Alexandria, Va., these two stayed mostly to themselves. They seemed transfixed when they landed on a branch and began their dance.
“I was fascinated by migration at a very early age,’’ said Farnsworth, who works out of New York City and oversees the lab’s 
As water levels have risen in coastal nesting places, the Spoonbills have looked elsewhere to find the unique environment they need. That in turn has helped them to spread their reach beyond heavily developed South Florida and the Everglades that had been their primary Florida breeding grounds for decades.
One year ago this month, we got a chance to witness this colony of Magnificent Frigatebirds in the midst of the birds’ unusual mating rituals. With the breeding season starting once again, we wanted to delve into a love story that’s remained relatively unchanged for millions of years. It attracted the attention of Charles Darwin when he was studying on the Galapagos Islands to get a glimpse of the origins of life.
First he inflates a gland sac in his throat so that it looks like a red, nearly heart-shaped balloon. Then he waves his head around to show off the balloon while clattering his beak. The females fly in circles overhead, reviewing their options.
“They’re very successful at raising chicks,” said Dr. Schreiber.
Birding magazines are a bit like seed catalogs, but they just weren’t doing the trick. Then, on Facebook, I discovered an extremely entertaining way to help fill the void.
