“…Common terns at colonies in MA and NY fed their chicks 30%–78% FO NWA Ammodytes during similar time periods (Appendix S1: Supplemental 8). Adult terns at colonies in the northern Gulf of Maine and Nova Scotia, Canada, delivered a combination of (mainly) NWA Ammodytes , Atlantic herring, and hake to their chicks (Kirkham, 1986; Rock, Leonard, & Boyne, 2007a, b; Shealer & Kress, 1994; Yakola, 2019). Regional populations of common and roseate terns staging (i.e., pre‐migratory) on Cape Cod, MA, were observed feeding almost exclusively on NWA Ammodytes for up to six weeks in late summer and early fall before departing for South America (Althouse, 2016; Jedrey, Harris, & Ray, 2010; J. Spendelow, personal communication).…”

The American sand lance (Ammodytes americanus, Ammodytidae) and the Northern sand lance (A. dubius, Ammodytidae) are small forage fishes that play an important functional role in the Northwest Atlantic Ocean (NWA). The NWA is a highly dynamic ecosystem currently facing increased risks from climate change, fishing and energy development.

“…The distances between the colonies ranged from 10 to 90 km. Arctic Tern foraging ranges are typically <10 km from the colony (Rock et al 2007, Thaxter et al 2012, and so the foraging ranges of individuals from these colonies are not likely to overlap much. Colonies also varied in size, ranging from 50 to 10 000 pairs.…”

“…Although Common and Arctic Terns target similar species of prey fish and invertebrates (Rock et al 2007) differences in the proportions of prey types consumed by each species, and differences in habitat use, with Common Terns tending to feed inshore and Arctic Terns tending to feed offshore, suggest a degree of resource partitioning (Braune and Gaskin 1982, Hall et al 2000, Hatch 2002). These differences in habitat and foraging behavior, coupled with the known differences in their migratory routes, suggests that patterns of movement during the postbreeding season (postbreeding staging and dispersal) would likely differ between the species.…”

ABSTRACT. In the western North Atlantic, Common (Sterna hirundo) and Arctic (S. paradisaea) Terns are sympatric at breeding colonies but show divergent migration strategies to coastal areas of South America and pelagic regions of the Antarctic, respectively. During 2013, we studied postbreeding movements of adult Common (n = 130) and Arctic (n = 52) Terns from four breeding colonies in the eastern USA and Canada using digital very high frequency (VHF) transmitters and an array of 62 automated radio telemetry towers. Relative to hatch dates at respective colonies, Arctic Terns departed breeding sites an average of eight days later than Common Terns. Common Terns were detected during the postbreeding period by coastal towers upward of 850 km south of their original nesting sites. The telemetry array detected postbreeding movements of Arctic Terns from the Petit Manan Island colony in the Gulf of Maine as they traveled eastward past Nova Scotia, Canada, mostly during the night. Nantucket Sound, Massachusetts, USA was identified as an important staging area for Common Terns from all colonies, whereby 26% of 53 tagged Common Terns from colonies in the Gulf of Maine and Canada were detected for up to three weeks. Common Terns typically arrived at Nantucket Sound within 2 h of sunset, 2 to 10 days after their last detection at Gulf of Maine and Canadian colonies, suggesting rapid postbreeding dispersal. Postbreeding dispersal of Arctic Terns was poorly documented with the telemetry array, suggesting that this species is not using coastal sites for staging, and is instead departing directly from colonies to offshore staging areas prior to long-distance migrations. We conclude that digital VHF telemetry is a useful method for monitoring regional movements of Common Terns, but additional offshore receiving stations are needed to effectively monitor movements of Arctic Terns away from their nesting colonies. Le réseau de télémétrie a détecté les déplacements postnuptiaux de Sternes arctiques de leur colonie de l'île Petit Manan, dans le golfe du Maine, au moment où elles se déplaçaient vers l'est au large de la Nouvelle-Écosse, Canada, le plus souvent durant la nuit. Le détroit de Nantucket, Massachusetts, É.-U., a été identifié comme halte migratoire importante pour les Sternes pierregarins en provenance de chaque colonie : 26 % des 53 Sternes pierregarins suivies dans les colonies du golfe du Maine et du Canada y ont été détectées pour une période allant jusqu'à 3 semaines. Les Sternes pierregarins arrivaient généralement dans le détroit de Nantucket dans les deux heures précédant le coucher du soleil, de 2 à 10 jours après leur dernière détection aux colonies du golfe du Maine et du Canada, indiquant une dispersion postnuptiale rapide. La dispersion postnuptiale des Sternes arctiques n'a été que très peu captée par le réseau de télémétrie, ce qui laisse croire que cette espèce n'utilise pas de sites côtiers comme haltes migratoires, mais quitte plutôt les colonies pour se rendre directement à des haltes au large, avant ...
