What does a wildlife comeback look like? A recovering island colony, a growing tiger estimate, a modest rise in rhino numbers and a slow return from the brink of whaling tell different stories. Here’s what changed and how to read each count.
Removing invasive rabbits gave burrow-nesting seabirds room to breed again. The study estimates nearly 90,000 breeding pairs in 2024, up from about 12,000 in 2013.
The October 15 study measures one Chilean island. Its two surveys estimate breeding pairs, with uncertainty around both counts.
Ranger patrols, prey restoration and protected habitat give tigers the space and food to raise cubs. Thailand’s 2026 estimate was 210, compared with a range of 148–189 in 2022.
WWF reported Thailand’s national estimate on October 8. The improvement is specific to Thailand; nearby countries have different trajectories.

Protecting rhinos and reconnecting habitat can help populations grow across borders. The latest report cites about 4,075 greater one-horned rhinos, compared with 4,014 in 2022.
The September 10 report repeats a previously published estimate for India and Nepal. Other rhino species face very different risks.

Decades after commercial whaling nearly wiped them out, Antarctic blue whales appear to be increasing. Researchers combined whaling records, ship surveys and photo IDs to estimate about 418 whales in 1973 and about 4,000 in 2024.
The November 5 study uses a model and the 2024 estimate has a wide uncertainty range. Even its central estimate is only about 2% of the pre-whaling population. Antarctic blue whales remain critically endangered.
