The largest colony of penguins in the world, located on Zavodovski Island, has experienced a drastic loss of 62.93% in breeding pairs of chinstrap penguins between 2011 and 2025, while macaroni penguin pairs have increased by 28.22%, indicating a significant ecological shift in the region, possibly due to ocean warming and the reduction of Antarctic krill availability. #Pingüinos #Conservación #CambioClimático (translated)

The guano accumulated in these bird populations, which can gather tens of thousands of individuals, generates extraordinarily intense methane emission hotspots that had not been measured or quantified on the ground until now,” explains Alejandro Román, researcher at ICMAN-CSIC and the first author of the study. #Pingüinos #Metano #Antártida (translated)

The colonies of chinstrap penguins in Antarctica emit approximately 490,000 tons of methane per year due to the decomposition of their guano, and it is estimated that this number could reach up to seven million tons when considering the entire area influenced by these birds. #Pingüinos #Metano #Antártida (translated)

Científicos han descubierto una nueva especie de pingüino, denominada Pygoscelis kerguelensis, en las islas Kerguelen de la Antártida, marcando la primera identificación de una nueva especie de pingüino en un siglo, tras un análisis genético que evidenció diferencias significativas con otras poblaciones. #Pingüinos #Antártida #EspecieNueva
