A high-pitched, tinkling birdsong rings across the open, grassy expanse of a field.
The song comes from above, as a male Horned Lark hovers on fluttering wings, circling a hundred feet above the ground.
Although a locally common nester in some open habitats of the West, the population in general has decreased by 56% in the last 40 years.
Loss of suitable habitat is the cause.
