Editing Nighthawk (section)

== Diet ==
Nighthawks are visually reliant predators that feed on flying insects such as beetles (Coleoptera), sawflies, bees, ants, and wasps (Hymenoptera), flies (Diptera), caddisflies (Trichoptera), butterflies, and moths (Lepidoptera) by opening their wide mouths to allow for the entrance of the insects as they are traveling.<ref name=":1" /> Areas of high precipitation, cool temperature, or high elevation are therefore unfavorable to nighthawks because flying insects are less mobile in such conditions.<ref name=":1" /> Nighthawks are most often observed hunting during crepuscular periods, or during twilight, which necessitates good eyesight with insects shorter than 5mm eliciting no reaction from experimental nighthawks.<ref name=":1" /> This consideration could pose a long-term risk to nighthawk population stability as climate change is increasing vulnerability in larger insects due to extreme weather events and higher temperatures, thus restricting prey availability for nighthawks which cannot see the, in some circumstances, 20% smaller prey organisms.<ref>{{Cite journal |last=Pennisi |first=Elizabeth |date=January 2018 |title=Large beetles are shrinking, thanks to climate change |url=https://www.science.org/content/article/large-beetles-are-shrinking-thanks-climate-change |journal=Science}}</ref>
