Un ruiseñor de tan solo 25 gramos acumula reservas de energía para cruzar el Sáhara. Investigadores de Lund utilizaron sensores en miniatura para rastrear a diez aves durante su migración desde Suecia hasta el sureste de África.

Investigadores de la Universidad de Lund utilizaron una nueva tecnología de sensores en miniatura para estudiar cómo los ruiseñores gestionan su larga migración sobre el Mediterráneo y el Sáhara. Las aves alegran los veranos suecos pero pasan el invierno principalmente en el sureste de África. Vuelan intensamente durante cuatro o cinco noches seguidas, descansando por completo durante el día. En el desierto, no pueden repostar y sobreviven gracias a las reservas acumuladas previamente, señaló el profesor de biología Anders Hedenström. "Estas aves no se arriesgan. Toda su estrategia se basa en haber acumulado suficiente energía antes de comenzar las partes más inhóspitas del viaje", afirmó Hedenström en un comunicado de prensa.

Rescued African penguin chicks recover well after Bird Island floods

Nearly 50 African penguin chicks rescued from flooding on Bird Island are now healthy and gaining weight under expert care at a rehabilitation centre in Gqeberha. The chicks were evacuated after heavy rains on 24 February washed away their nests. Climate change is exacerbating such threats to seabird colonies.

Extreme weather impacts growth of great tit nestlings

A 60-year study of over 80,000 great tits in Oxford's Wytham Woods shows that cold snaps and heavy rain reduce nestling body mass and survival chances. Birds breeding earlier in the season appear better shielded from these effects. Moderate warm spells, however, can boost chick growth by enhancing food availability.

Polar bears in Svalbard grow fatter despite rapid warming

In Norway's Svalbard archipelago, the fastest-warming region on Earth, polar bears have surprisingly increased in size and weight since 2000, even as sea ice diminishes. Researchers attribute this to adaptive foraging behaviors amid shrinking ice. However, experts warn that long-term survival remains threatened by ongoing climate change.

Following the Sundsvall Administrative Court's March 17 decision to lift a temporary halt, the license hunt for lynx in Dalarna has resumed amid ongoing appeals. Hunters are permitted to shoot 20 lynx—nearly double last year's quota—while the Nature Protection Association, which appealed in 11 counties, criticizes the move.
