Our new State of the World’s Migratory Species: Interim Report 2026 has found that a number of species that previously had stable populations are decreasing. 26 CMS-listed species have moved to higher extinction risk categories.

Migratory animals connect the planet but they are facing unprecedented pressures. #CMSCOP15 in Brazil is the best opportunity to strengthen international cooperation and adopt transformative measures that will secure their future and safeguard their habitats.

Migratory species depend on networks of habitats. When these connections remain intact, they can move freely, ecosystems stay resilient, and natural processes that sustain life continue to flow.

Participants at #CMSCOP15 will seek to maintain, restore & strengthen these networks: www.cms.int/cop15

Indigenous knowledge confirms what scientists observe: Large birds are disappearing Many Indigenous peoples and local communities live in close contact with nature and learn to identify the wildlife around them from an early age. New research published in the International Journal…

"All the big birds are now gone."
This observation from a Kenyan elder reflects a global pattern. A new study shows that Indigenous ecological memories across three continents align with scientific data: Large, slow-breeding species are being lost to habitat change and hunting.

Avian flu strikes California’s northern elephant seals; area quarantined Ever since a deadly strain of avian influenza, H5N1, killed some 17,000 southern elephant seal pups on South American coastlines in 2023 and 2024, researchers and public officials have kept an…

Seven young northern elephant seals at California’s Año Nuevo State Park tested positive for H5N1, marking the first known infections in the species.

The virus has hit hundreds of bird and mammal species worldwide. Officials have closed the beaches as a precaution.

Climate change is slowing southern right whale birth rate, 33-year study finds Southern right whales (Eubalaena australis) off Australia’s southern coast are having calves less often than they used to. A new study links this slowdown to warming water and shrinking sea ice in…

A 33-year study finds southern right whales off Australia are calving less often, with birth intervals rising since 2015.

Researchers link the slowdown to climate-driven declines in krill and copepods, warning similar trends worldwide could threaten a species still recovering from whaling.

As ocean temperatures and conditions shift, predators and prey are falling out of sync, causing cascading effects across marine ecosystems in South America, Southern Africa, Australia and New Zealand.

Why are Procellariiform seabirds most diverse in the Southern Hemisphere?

[COMMENTARY]

This October, as delegates gather to discuss CCAMLR priorities, the authors of a new commentary argue, “At stake is more than a fishing rule, but also the commitment to manage fisheries proactively, rather than reactively.”

Schematic diagram of the influence of seabirds on temperate and tropical near-shore marine systems.
Temperatre systems:
- Nutrient enrichment and predation on herbivorous invertebrates can lead to increased algal production
- Phytoplankton communities change, featuring more large-celled species
- Intertidal organisms incorporate seabird-enriched material by grazing on detritus and biofilm in tidepools
- Macroalgae biodiversity and primary production are boosted
Tropical systems:
- Mangrove leaf nutritional quality increases
- Corals recover faster after bleaching events
- Fish biomass increases across different trophic groups
- Pelagic and benthic consumers' foraging behaviour shifts
- Parrotfish grazing and bioerosion rates increase
- Fish grow larger
