The song that fades: more than half of the world's birds are in declineBy Estefanía Muriel for Ruta Pantera on 10/23/2025 11:31:22 AM |

| Experts urge governments to turn environmental promises into concrete actions. According to a new global report, 61% of assessed bird species are experiencing population declines, a significant jump from 44% nine years ago. (The Guardian) This trend coincides with the opening of the International Union for Conservation of Nature (IUCN) congress in Abu Dhabi, where world leaders are gathering to address what many are calling an unprecedented biodiversity crisis. (The Guardian) The report points to multiple factors, with deforestation being one of the most critical: the conversion of forests to agricultural land and human development continue to erode essential bird habitats. (The Guardian) Furthermore, as biologist Ian Burfield points out, “The fact that three out of five of the world’s bird species have declining populations shows how profound the biodiversity crisis has become.” (The Guardian) Tropical ecosystems, such as the forests of Madagascar and Central America, are among the most affected. Furthermore, birds perform key ecological functions—such as pollination, seed dispersal, and pest control—which means their decline can have knock-on effects for the ecosystems on which they depend. | ||||

What***s at stake When bird populations decline, it***s not just a species that is lost; the web of ecological relationships that keep ecosystems healthy also suffers. As Malin Rivers noted, "The fates of birds and trees are intertwined: trees depend on birds to regenerate, and birds depend on trees to survive." (The Guardian) If these trends continue, they could trigger ripple effects ranging from soil fertility to the ability of ecosystems to withstand extreme weather events. Yes. While the overall situation is worrying, there are also success stories that demonstrate that conservation can work. The report highlights that the green sea turtle—a species that was once in critical condition—has been reclassified as “least concern” thanks to decades of protection of its nesting areas and coordinated international efforts. (The Guardian) This type of progress fuels the idea that, with political commitment, adequate resources, and effective governance, the trajectory for other endangered species can be reversed. Call to action Researchers leave no room for passivity. According to the IUCN report, “Act to help seals is act to help humanity on climate change,” also referring to other species such as Arctic seals facing the loss of sea ice. (AP News) For birds, this means reaffirming international commitments, greater investment in habitat protection, implementing sustainable agricultural and forestry policies, and increasing public awareness of the importance of biodiversity. The biodiversity clock does not stop The fact that more than half of the world***s bird species are in decline is no small feat: it***s a warning sign for the health of the planet. Although the challenges are enormous, the success of the green turtle demonstrates that conservation can deliver results. But achieving this requires concerted action, resources, and political will. The IUCN Congress in Abu Dhabi opens a window of opportunity: one wonders whether leaders will take advantage of this opportunity to translate words into action before many more species become prey to silent extinction. | |||
