The autumn migration of Jack Snipe Lymnocryptes minimus was studied using mist-netting at night along a muddy shoreline at Lake Tåkern in southern central Sweden. During ten consecutive autumn seasons ranging from mid-September to mid-November a total of 107 birds were captured, particularly within the first two hours after dusk. The peak of migration occurred in the first ten days of October with the juvenile birds on average passing a few days earlier than the adult birds. We present information on movements and ringing recoveries and review the challenges of ageing the species. We propose that crepuscular mist-netting near wetlands offering important staging grounds may be a suitable method to monitor the migratory movements, and possibly the population dynamics, of this little-studied species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
