An avoidable cat-astrophe in Western Australia. Every month ~800 pet cats and ~4M birds, mammals & reptiles die because current policy prevents pet cats from being contained. This paper reveals broad support for change: 78% of local govts want containment laws. Let's get this done.

Happy New Year folks! In 2026 I'm hoping to bring the vibe of this northern pygmy owl, feat dead mouse. I hope you manage to catch your mice too, or learn things in the process, be kind to yourself and others, and find the space to try again. ✨️🦉

Revered and reviled, cats in the crosshairs on Christmas Island On a speck of land in the Indian Ocean, one of the world's most ambitious wars is being waged against feral cats. But not everyone is celebrating.

A great story on the impacts of cats on islands, showcasing Christmas Island's story. Amazing work and an amazing team.

With ‘terrifying’ trade in African hornbills, scientists call for increased protection For millions of years, the African landscape — the rainforests, woodlands, savannas and scrublands — has echoed with the booms and cackles of large, raucous, strange-looking birds: hornbills. When…

With an alarming rise in the international trade of African hornbills, wild populations are plummeting. As key seed dispersers, their demise also threatens the survival of the forests they inhabit.

In memory of the Christmas Island shrew It never weighed more than a spoonful of sugar. Five or six grams of life, soft-furred and sharp-nosed, darting among the roots and leaf litter of a tiny island in the Indian Ocean. At night, its…

Once abundant on Christmas Island, the tiny, five-gram shrew filled the night forest with its high, thin cry before vanishing into silence.

Its loss adds to Australia’s grim record of extinctions—a quiet reminder of fragile lives erased by invasion, neglect, and the noise of human expansion.

💫 Management of caribou threats may benefit wolverine, but a complete management strategy for wolverine would rely on effective caribou conservation actions that have meaningful on-ground impacts and the management of additional wolverine-specific threats.

🔍 For wolverine, current conservation objectives are not well defined. Only four conservation documents list recovery actions for wolverine, and the most recent national document (2014) does not list any. This leads to a disconnect between identified problems and proposed solutions.

🌿 Many threats relevant to wolverine and caribou may be addressed through effective management of caribou critical habitat,which implicitly involves managing for the cumulative effects of industrial disturbance. Is this being effectively done in Canada? Probably not.

🏭 We found considerable overlap between wolverine and caribou in listed threats and recovery actions. Habitat loss, hunting and trapping, sensory disturbance, and linear features were all key threats to both species.

🍁 We systematically reviewed conservation documentation and scientific literature to investigate the extent woodland caribou-focused conservation is likely to benefit wolverine. Writing this paper, I learned so much about how conservation works in Canada.

Here’s a few things that stood out to me:

Wolverine in the slipstream: A systematic review of caribou‐focused conservation benefits, gaps and uncertainties for wolverine in Canada With rates of biodiversity loss accelerating globally, debate exists regarding the most efficient ways of allocating resources to conserve species. Woodland caribou are the focus of many Canadian con...

It encourages kids to spot similar features in completely different groups of animals, and to wonder why. Why are so many animals spiky?🦔 Or have white bellies and black backs?🐧 Or paddles?🦭 Or venom?🐍 Or eyes on tops of their heads?🐊 a.co/d/31fo6M4

It's #InternationalPallasCatDay! Finding wild Pallas's cat was one of the most amazing experiences of the last year. It was hunting voles on a Himalayan plain, wriggling its tail - the only part of its body that isn't camouflaged - presumably to distract the voles. #MammalWatching #WildIndia #Ladakh

‘Endearing and fascinating’ yellow-bellied glider faces ‘inexorable slide’ into extinction Guardian Australia is highlighting the plight of our endangered native species during an election campaign that is ignoring broken environment laws and rapidly declining ecosystems * Explore the series – Last chance: the extinction crisis being ignored this election * Get Guardian Australia environment editor Adam Morton’s Clear Air column as an email Australia’s most skilled aerial mammal, the yellow-bellied glider, is on an “inexorable slide” to extinction as global heating creates more extreme bushfires that are robbing the species of the food and tree hollows it relies on to survive. Thanks to large parachutes of skin stretching from their wrists to their ankles, yellow-bellied gliders can travel up to 140 metres in a single jump, the furthest of any Australian mammal, including the larger and better known endangered greater glider.

Their evolution is pre ice. They are tough. Birds that can go through interglacial/ glacial times (hothouse / icehouse 🔄) are tough. We can learn from penguins 🐧

In our new paper, we argue why a clear, size-based definition (>10,000 ha) of megafire improves research, communication, and fire management globally. 🔥
