How do potoos reduce competition with nightjars for food?

Competition between potoos and nightjars is reduced primarily through differences in their hunting strategies and spatial niches. While both groups consume similar types of insects, potoos hunt by making sallies from higher, exposed arboreal perches in open country.12

In contrast, nightjars often prefer to forage in continuous flight or by swooping from lower perches, and they frequently utilize the edges of forests or clearings. Furthermore, potoos exploit the vast niche located in the space above great forests, an area that is occupied by practically no other nocturnal bird.12
