In October 2018, the [[University of Alberta]] published research on the common nighthawk revealing that it travels {{Convert|20000|km|mi|abbr=on}} every year during migration between the rainforests and savannas of Brazil and its breeding grounds in northern Alberta.<ref>{{cite web |last=Willis |first=Katie |date=October 1, 2018 |title=Scientists track nighthawks' migration route in search of clues to species' steep decline |url=https://phys.org/news/2018-10-scientists-track-nighthawks-migration-route.html |access-date=October 1, 2018 |publisher=[[Phys.org]]}}</ref> Further research has determined that, in addition to this annual migration between general regions, nighthawks demonstrate a high breeding site fidelity, thus meaning they are especially susceptible to destabilization as a result of natural disasters such as forest fires, floods or droughts, as well as anthropogenic interventions such as development.<ref name=":3" /> Nighthawks have been observed migrating at all hours of the day in flocks of, at times, hundreds of birds which winter in both rural and urban regions of South America.<ref name=":5" /> Nighthawk migration is considered one of the longest routes traveled for any North American bird.<ref name=":5" />
