claimThe energetic costs of extending the Arctic portion of the non-breeding route for short-tailed shearwaters could negatively impact their survival and reproductive success.

claimShort-tailed shearwaters make few foraging stops when migrating from the Arctic to their Australian breeding grounds.

claimInterannual variability in spatial distribution during migration is common for species such as short-tailed shearwaters, black-legged kittiwakes, and red phalaropes.

referenceGlencross, Lavers, and Woehler (2021) examined the breeding success of short-tailed shearwaters following extreme environmental conditions.

claimThe influx of Aethia auklets and short-tailed shearwaters into the eastern Chukchi Sea reflects a shift in their post-breeding migration to forage on newly abundant late summer resources, as these species do not nest in the region.

claimThe increase in planktivorous seabirds in the offshore eastern Chukchi Sea is primarily attributed to abundance increases for two species of Aethia auklets, which feed on copepods and small euphausiids, and short-tailed shearwaters, which feed on larger euphausiids and small fish, as noted by Kuletz et al. (2015) and Gall et al. (2017).

claimIn the eastern Chukchi Sea, zooplankton-feeding seabirds like Aethia auklets and short-tailed shearwaters (Ardenna tenuirostris) were more abundant in offshore waters during the 2000s compared to the fish-eating seabirds (alcids and larids) that dominated the same area from 1974 to 1995.

claimShort-tailed shearwater populations increased in abundance but shifted their distribution to the shallow Chukchi Shelf, moving away from previously identified hotspots.

claimYamamoto et al. (2015) observed that the annual and seasonal migration movements of short-tailed shearwaters are reflective of environmental variations in sub-Arctic and Arctic waters.

claimShort-tailed shearwaters (Ardenna tenuirostris) have gradually shifted their migratory route northward since approximately 2014.

referenceNishizawa et al. (2017) analyzed the seasonal distribution of short-tailed shearwaters and their prey in the Bering and Chukchi seas.

claimFor short-tailed shearwaters, the Chukchi Sea represents the northernmost extent of their seasonal migration from breeding grounds in Australia, according to Yamamoto et al. (2015).

claimDuring an anomalously warm period from 2017 to 2019, significantly fewer Aethia auklets migrated into the Chukchi Sea in late summer and fall, and short-tailed shearwaters altered their distribution across the Chukchi Shelf, indicating that migration shifts are not a linear response to Arctic warming.
