Las aves que migran a más distancia acusan el cambio climático
A study of Arctic terns tracked with electronic tags revealed changes in their migration behavior linked to climate change. Researchers compared data from 47 trips in 2015 and 2017 and found differences that coincided with a shift from thick sea ice to unusually warm conditions. The warmer period likely reduced juvenile krill, the birds' main food source, forcing them to feed in new areas.
- ▪Electronic tags were attached to 47 Arctic terns to monitor their long-distance migrations during 2015 and 2017.
- ▪The team observed marked differences in the birds' behavior and distribution between the two years.
- ▪These differences aligned with a transition from a high sea‑ice cover in 2015 to unusually warm temperatures and reduced ice in 2016‑2017.
- ▪Scientists linked the reduced sea‑ice to lower juvenile krill abundance, which is the primary prey of Arctic terns, prompting the birds to forage in different locations.

Las aves que migran a más distancia acusan el cambio climático Regala esta noticia Añádenos en Google Golondrina de mar ártica. . (LP) 28/11/2019 a las 02:17h. Datos recopilados de etiquetas electrónicas recuperadas de 47 viajes realizados por golondrinas de mar árticas revelan por primera vez cómo el cambio climático puede afectar su comportamiento. Las golondrinas de mar árticas pasan sus temporadas reproductivas y no reproductivas en ambientes polares en los extremos opuestos del mundo, y son el ave marina que realiza la mayor migración en distancia recorrida. Al pasar su temporada de no reproducción en la Antártida, la lejanía de esta parte del mundo significa que hasta ahora hemos tenido una comprensión muy limitada de su comportamiento y distribución mientras están allí.
