Abstract

We report some interspecific nocturnal tandem flights involving the Eurasian woodcock and other terrestrial non-passerine species such as the Japanese green pigeon in two bird observatories in northern Japan. Our observation suggests that this previously undescribed interspecific interaction may be a novel form of commensalism or mutualism in nocturnal migrants. Here we upload the supporting dataset that includes the date and time, abundance, the presence/absence of nocturnal flight calls, flight direction, flight altitude, and observation location for each observed pass-by species.
