In the book, Trilli is part Common Nighthawk and part Trilling Nighthawk. Her diving instructor and friend Tridente is pureblood Common Nighthawk, and so are her fairy-chasing relatives Perigretti, Tornado, and the Crew.
Nighthawks roost and nest on the ground in the thick cover of the pine forest, grass or sagebrush.
They hunt for insects mostly at dawn and late evening. They are very effective hunters because of their sonar which can identify prey as they soar through the air. When they hunt, they usually fly fairly high in the sky, and when they detect an insect, they fold their wings close to their bodies and dive straight for their prey. They have very big mouths which they open wide to catch flying insects. Nighthawks are easily recognized in flight by the white band on the underside of each wing.
