For the chance to admire a flock of Utah’s most rakishly handsome songbirds, look to the sky or trees when you hear this call:
[Kevin Colver, Cedar Waxwing, Songbirds of Yellowstone and the High Rockies...]
That high, thin whistle indicates waxwings. All winter long, waxwings stick together in dense, cohesive flocks that fluidly fly and forage as one. Like locusts, a flock will swarm over a mountain ash, juniper or hawthorn, quickly stripping it of the small fruits that constitute their diet. They eat a wide variety of small fruits from berries to grapes to cherries. Cedar waxwings are commonly seen throughout Utah all winter long. They are nomadic; traveling to where ever fruit is abundant.
Some winters, Cedar Waxwings are joined here by their northern cousins, the Bohemian waxwings. Both waxwings are debonair, with a sweptback crest and an angular black Zorro mask. The name waxwing refers to a line of scarlet waxy droplets at the tips of specialized wing feathers. More likely you’ll notice the bar of lemon-yellow feather tips across the tail. Both of those colors come from pigments in their fruity diets. The body of the smaller Cedar waxwing is more caramel-colored than the grayer Bohemian waxwing. Bohemian waxwings have a distinct rufus patch of feathers beneath the tail.
So remember to pay attention when you hear that high-pitched whistle and look around you for trees decorated with these snazzy-looking waxwings. They will surely put some zing in your drab winter day.

I didn't find the waxwing call at your link, but Cornell is a reliable site for bird calls:
