Just out: Scientific report with overview of highly pathogenic avian #influenza from December 2022 to March 2023, by @efsa, @ECDC_EU, and EURL AI. A thread on the situation in poultry, wild birds, wild mammals, and humans in Europe and worldwide. (1/11)…
In #Europe, highly pathogenic avian #influenza virus #H5N1, clade, was reported in 403 #poultry farms and 119 other captive bird holdings birds in 24 countries between 3 December 2022 and 1 March 2023. (2/11)
In Europe, an unexpected number of highly pathogenic avian #influenza virus #H5N1 detections in #seabirds were observed between 3 December 2022 and 1 March 2023, mainly in gull species and particularly in black-headed #gulls (Chroicocephalus ridibundus). (3/11)

Second post in the #WildlifeWeek series.

Day 2 – Squeals return to the tall wet #grasslands of #Assam !!!
Pygmy Hog is the tiniest, rarest and the most #endangered of all wild #pigs globally. In fact, phylogenetic analysis of the pygmy hog revealed that it belongs to a separate genus, Porcula. It is evolutionarily unique and completely different from #boars, #warthogs, and pigs.
Known to once thrive in the lush tall and wet grassland plains of the sub #Himalayas, they were feared to be extinct in the 1960's but were “rediscovered” in the year 1971.

A brief thread on #mammals that are are alive today but were first described as #fossils.... 1/n
Goosebeak or Cuvier’s beaked #whale (#Ziphius cavirostris): described as a fossil in 1823 but realised in 1872 to be the same as beached specimens reported in 1820s but given different names. Ziphius is near-globally distributed (pics: specimens from Bay of Biscay; NOAA) 2/n
Bush dog (Speothos venaticus): named as a fossil in 1839 - which explains Speothos, meaning ‘cave wolf’ - and described alive 1843. The same person, Danish naturalist Peter Wilhelm Lund, described the fossil AND living animals, but ... 3/n (pics Attis; Bonne1978; CC BY-SA 3.0)

Here is a list of 45 #birds, 22 #mammals, and 30 non-avian #reptiles that are CRITICALLY ENDANGERED due to feral or pet #cats
#invasivespecies #conservation #ornithology #BiodiversityCrisis… Image
first off, I'd like to highlight that "feral #cats on islands are responsible for at least 14% global #bird, #mammal, and reptile extinctions and are the principal threat to almost 8% of critically endangered birds, mammals, and reptiles"…
AND within our own lifetimes, North America has lost more than one in four of its birds. These are not all critically endangered now, but these trends are pointing to #extinction

Do you purport to care about #conservation? Keep your damn cats indoors and minimize their threat to #birds, #mammals, & lizards.

#cats that are allowed to roam outside, feral or otherwise, are a major threat to our #wildlife and #biodiversity.
There’s fantastic studies on the threat to #wildlife that outdoor #cats pose in Australia. But don’t be fooled into thinking this problem is restricted to just Australia—#feral and free roaming cats are contributing to millions of wildlife deaths every year in the USA.
Thanks to @tiredguineapig for highlighting these fantastic Infographs in a recent tweet. We need these for Europe and the US!

Have you ever thought about how we monitor #wildlife? In this thread🧵 I will explain my #PhDthesis

#CREAF20K #cameratraps #mammals #conservation
Traditional methods of studying wildlife were based on direct observation of animals🧐🔭.
However, the technological boom of recent decades has also changed the way of monitoring wildlife. Do you want to know how?
Keyword is #cameratrap 📸!!
#Cameratraps are remotely activated cameras by an infrared sensor. When an animal passes in front of them, they record photos. Cameras operate with batteries and SD cards, we can place them in remote areas. Finally, animals don't react to them and showed their habitual behaviour

I just can't believe we're halfway through the year already. I haven't done much at #TetZoo - just no chance - but here's a quick thread of personal highlights of 2022 so far... ImageImageImageImage
First off, I enjoyed putting together my lookback at the 2001 #DorlingKindersley Encyclopedia of #Dinosaurs & Prehistoric Life, a book I co-authored and helped put together during my formative PhD-focused years…
The recycled article on Kogia - the dwarf and pygmy sperm whales - was fun to reassemble...… #mammals #marinemammals #cetaceans #whales

Honoured to share that @IngridOlivaresa and I have started a beautiful project with the @TaironaTrust and the #Kogi Indigenous People of #Colombia to #restore degraded lands and revive #water in the #SierraNevadadeSantaMarta Thread 👇 (1/11) Image
The Sierra Nevada de Santa Marta is a @UNESCO biosphere reserve since 1979. It has the world’s highest coastal peak (5730m) and all the climatic zones of tropical America: from mangroves to glaciers. Image
Biologically, the Sierra has > 3,000 species of vascular #plants, 120 #mammals (including jaguars, pumas, and tapirs), and 628 #bird species. Many species are only found there, such as the Santa Marta Parakeet. Image

There's a lot of #badnews about #biodiversity and #conservation at the moment, so how about some #conservationoptimism? 🧵 based on our new paper… and some awesome recent work by others... 1/
As you probably know, the world has ambitious targets to protect 17% of the world's land for #biodiversity #conservation, and there are calls to increase this to anywhere between 26-60% in the next round of @UNBiodiversity talks (this year) 2/
In theory, this is great for biodiversity (more on the human impacts later). Problem is that the total area of land that you protect may not be important: a lot of #protectedareas are small or isolated, and this means that the populations are also small and isolated 3/

Exactly! Humans are now responsible for these extinctions as the planets Apex Predator!
Humans are responsible for most mammalian extinctions for the past 125,000 years. That's an insane amount of time!
The rate at which mammals are going extinct is also going up as we humans continue to change the climate. Polar bears for example, losing their habitat due to the melting ice caps, which we have been causing since the industrial revolution. Also rainforest are being cut down.

🕉 #WeekendWisdom - A beautiful story from #ShatpathaBrahmana about creation of different #animal species - #Prajapati #Brahma had created the #aquatics 🐠 #birds 🐦 & #reptiles 🐊 who reproduced by laying eggs. But many of them kept perishing from want of adequate food... 1/3
So #Brahma decided to give his next creations the means of survival by providing them breasts that could produce nutrition for the newborns.

By resorting to this milk the new species created by him continued to thrive and thus came #mammals including us! 🦧🐈🐕‍🦺🐅🐆🐏🧍‍♂️... 2/3
This story also shows us the concept of #evolution because we, the mammals, have appeared much after the older species that inhabited this planet!

Palm oil corporations, whose products are found in so many of our foods, are gaslighting us & greenwashing a horrifically exploitative & damaging industry. They are responsible for deforestation and are driving many species to extinction.

For the return of the #UNMBioblog after our year hiatus, I chose to write about the negative consequences for cats, humans, and #wildlife when we allow #cats to roam freely. I couldn't help myself with the punny title.…
I was inspired to write this blog after I witnessed my neighbor's outdoor pet #cat killed a #bird under my feeder. A heated argument ensued. I know nothing has changed because I still scare him out of my backyard. I've counted 9 different cats in my backyard, here is one
I am a paradoxical #catlover, which stems from my #science & #ornithology career. I know how cute it is for my own #cat to frolic in flowers but I understand how dangerous it is for #cats, human #health, & #wildlife when cats roam #CatsOfTwitter #Caturday #catsofinstagram

THREAD - What happened at the Huanan #seafood market?

The @WHO report is quite clear on this point: #SARSCoV2 might have jumped from a wild animal sold in this market and maybe other markets in #Wuhan. But what do we know exactly? 1/15

#originsofSARSCoV2 Image
After all this time, the Huanan seafood market still remains the main suspect for a simple reason: most of the early cases had visited at least one market in Wuhan city, and several of them visited the Huanan market. 2/15 Image
According to the report, 10,000 people visited this place every day, making it a perfect setting for an #outbreak. One might argue: what about the cases without market exposure? Good question! 3/15

The African crested rat looks adorable, but its fur is packed with lethal poison—just milligrams can kill a human.

People in East Africa have known the rat to be poisonous but its source was mysterious.

The 2011 study hypothesized that the rats chew Acokanthera bark and lick the plant toxins into specialized hairs at the center of these stripes.

Time to embark on another of my #cryptozoology PHOTO MEGA-THREADS (from hereon, #TetZoocryptomegathread). Today: Rilla Martin’s 1964 Ozenkadnook tiger photo, aka the ‘Rilla critter’ photo, from western Victoria, Australia. It's one of my favourite mystery animal photos. Ok...
The photo – a single black and white image – shows a vaguely dog-shaped, long-tailed mammal in the scrub, assumed to be a predatory marsupial of some sort, but one which doesn’t match anything known to science.
The story is that Martin was holidaying with her cousin Bushy (yeah, ‘Bushy’) at Goroke on the Victoria/South Australia border (map from Google maps)...

Me and the family went to ZSL #LondonZoo today, had a great time and saw all the #animals. Here's a short thread. Some highlights: Western lowland gorilla, Sumatran tiger, Komodo dragon, Galapagos giant tortoise... ImageImageImageImage
Just a few of the literally 100s of birds at #LondonZoo: Woolly-necked stork, Northern crested caracaras (big, semi-terrestrial American falcons) and Red and yellow barbet. Barbets are members of the woodpecker group; some are close kin of toucans. #birds #animals #zoos ImageImageImage
Some #reptiles: the remarkably yellow Cuming's water monitor, an awesome Reticulated python (cue #HarryPotter link), Big-headed turtle (able to climb, prehensile-tailed) and Rio Fuerte beaded lizard... #lizards #snakes #squamates #turtles ImageImageImageImage

Let’s look at another famous ‘mystery animal’ image. This time the 'de Loys ape' photo of 1920(ish), taken in the Catatumbo River basin of #Venezuela. You surely know the photo already. But do you know its complicated backstory? Join me as we explore it in this loooong thread…
The photo shows a large, hairy primate, sat on a wooden box, a stick propping it up beneath the chin. The version shared most often is cropped, so you only see what looks like bare ground or the river behind the animal. #cryptozoology
The uncropped version shows the opposite river bank and some hacked-down plants surrounding the animal.... #primates #monkeys #mysteries
