Status and Conservation
There has been a general decline in the number of Common Nighthawks in North America, but some population increases also have occurred in other geographical locations. The bird’s large range makes individual risk thresholds in specific regions difficult to establish.
The Common Nighthawk’s trait of being a ground nesting bird makes it particularly susceptible to predators some of which include domestic cats, ravens, snakes, dogs, coyotes, falcons and owls.
Lack of flat roofs, pesticides, increased predation and loss of habitat are noted factors of their decline. Further, unstudied potential causes of decline include climate change, disease, road kills, man-made towers (as an aerial hazard) and parasites.
The absence of flat roofs (made with gravel) in urban settings is an important cause of decline. In an effort to provide managed breeding areas, gravel pads have been added in the corners of rubberized roofs; this proves acceptable, as nesting has been observed.

Famous quotes containing the words status and/or conservation:
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
“The putting into force of laws which shall secure the conservation of our resources, as far as they may be within the jurisdiction of the Federal Government, including the more important work of saving and restoring our forests and the great improvement of waterways, are all proper government functions which must involve large expenditure if properly performed.”
—William Howard Taft (1857–1930)
