Birds do it better: our latest work in @CurrentBiology shows their neurons consume 3x less glucose compared to neurons in the mammalian brain. Very excited to share the results of lasts years work with you! A🧵…
#Birds #Neuroscience #Evolution #SciComm
Brain tissue is metabolically costly. This is mostly caused by expensive neurons that need a lot of glucose. Across mammals, the neuronal energy budget appears to be fixed.
Birds pack many more neurons in their brains compared to mammals. This partly explains how they enable advanced sensory and cognitive processing capacity with such small brains. But how can they support such high cell numbers?

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!

THREAD: So if you love #fishing and your water, something to consider. I have bald eagles, trumpeter swans, pelicans, herons here on the Lower #Wisconsin #River. Lead kills #birds. I lose probably more than my share of jigs and hanging with the @riveralliancewi got me thinking.
I am more pragmatist than activist, but #environmentalism hits home as you watch eagles soar as you fish pristine, delicate waterways. The 92 miles LWR is mostly in conservancy, and is recognized as a @RamsarConv Wetlands of International Importance.
So I cultivated a local guy who makes lures out of his garage. Very skilled fisherman too and I have learned a lot from him out on the water. Had him cast me this initial run of jigs out of tin bismuth alloy.

Happy #WorldSnakeDay. #Snakes have an unfair reputation as being poisonous/ aggressive. Our fear of snakes may come from Christianity. Satan took the form of a snake tempting Eve in the Garden of Eden. Yet snakes aren't bad at all! They're critical to ecosystems around the world
#Snakes evolved 130 million years ago in the Cretaceous period from a common ancestor that they share with #birds and other #reptiles. They have cloacal spurs or vestigal limbs, which shows their shared ancestry with limbed reptiles. #WorldSnakeDay 🐍🐍🐍
#Snakes see on the infrared spectrum using heat receptors called pit organs making them epic predators with natural night vision goggles to see prey. Snakes have a detachable jaw which can swallow food whole that is much larger than its own body weight. #WorldSnakeDay 🐍💚

I want to share a story with you about an infamous American Robin, GG-XY (for green over green on left leg, metal over yellow on right; pictured).

📸@CKaster Image
This bird is a female who literally made the front page news last year, as the photo of her diligently feeding her young while sporting a GPS antenna festooned the feature by @APNews writer @larsonchristina. Image
It was a fantastic shot by @CKaster that showcased this awesome robin doing her annual rhythm of raising young while also showing how she'll be providing us this awesome data about where she spends her time throughout the year. Image

Our paper (with @LeaGrie) on the functions of #bird #odour is out in Biological Reviews…

Don’t have time to read the full paper just yet? Here’s a summary thread 🧵 [1/14]

#olfactory #camouflage #communication #ornithology #avian #olfaction #crypsis
Preen oil is produced by the uropygial gland and birds use it to maintain and waterproof their plumage. But could it have other functions? 🤔 [2/14]
Over the past 20 years, researchers have explored whether preen oil plays a role in chemical defence & communication. Despite this growth in research, many functions of preen oil remain poorly understood 🧐 [3/14]

🕉 #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!

On 25 Jan 2022, Japan released the second in its "Record of Nature" #stamps series. This issue depicts images from a set of 6 scrolls, dating from 1834, titled 禽鏡 (Kinkyo), in which there are 300 paintings of more than 200 #birds.
#philately Image
2. The scrolls are the work of the Edo-period Japanese novelist, Takizawa Bakin (1767-1848), who had his son-in-law, the painter Atsumi Kakusyu, paint the birds, adding his own commentary around them. Puctured is Bakin's portrait by the ukiyo-e artist, Utagawa Kunisada. Image
3. To follow, I'll show each stamp next to an actual scan of the scroll from which it was adapted. Shown here is the first scroll in the set. Image

¿Conoces las diferencias entre lechuzas, búhos, cárabos, mochuelos y autillos?
No es una respuesta fácil, los nombres comunes son bastante libres. Además, en España debemos tener en cuenta que el castellano es la lengua oficial o principal en 22 países.
#hilo #birds ImageImageImageImage
Otra nota importante: taxonomía y nombres comunes no tienen porqué correlacionarse. Por ejemplo, en España tenemos seis especies habituales del género /Turdus/, cuatro zorzales y dos mirlos. Además, existe el mirlo acuático europeo, ¡de una familia muy diferente! Image
¡Vamos al lío! Todas las rapaces nocturnas que trataremos en este #hilo se clasifican en el orden Strigiformes, con dos familias clásicas (gran consenso sobre esta taxonomía): Tytonidae y Strigidae.

Una travesía transoceánica en barco de NUEVE búhos nivales.

Además, muchos lemings, "invasiones" en USA, citas en Europa, más viajes en barco o crisis climática. Todo lo que querías saber sobre los búhos nivales y no te atreviste a preguntar. #hilo

#birds #birding #birdwatching
Tras la aparición de tres búhos nivales en el norte de España, algo insólito, surgen muchas preguntas acerca de su procedencia y futuro. Para ayudar a resolverlas debemos conocer aspectos importantes de su historia natural, remontándonos además años atrás.
"9 de diciembre de 2013. El carguero MSC Monterey transporta contenedores de Nueva York a Bremerhaven, Alemania. Se sitúa a 50 kilómetros al sur de Terranova y recibe la inesperada visita de nueve búhos nivales, dos machos y siete hembras, agotados."

1. The world's oldest known wild bird is a Laysan Albatros.

She is called Wisdom, because of her age and surviving many current threads like fish-lines, climate change, and plastic pollution. 

This is her. Isn’t she beautiful?

2. While I work on this thread (with more albatrosses videos), you could subscribe for The Planet newsletter.

3. Wisdom was probably born around 1951. Five years later, in 1956, the young albatross, got a red ankle band with the number Z333.

By now, that albatross, Wisdom, has become famous as the world's oldest known wild bird.

Time once more for a #TetZoocryptomegathread. Again, it’s on #seamonsters, and again on a supposed actual photo of a live one! I refer of course to the enigmatic Professor Sharpe ‘1908’ photo, which I first wrote about back in 2008…
The photo was brought to recent attention by cryptozoological researchers Dwight Smith and Gary Mangiacopra in a 2001 article, published in a special volume of Crypto devoted to aquatic #monsters...
It concerns a photo that’s been republished more than once since its first appearance in a Californian newspaper, and must have been seen by thousands, if not millions, of people… #cryptozoology #monsters

1. Both predators and prey animals use camouflage to their advantage.

Prey animals blend in with the background, so hungry predators pass right by them.

🧵 Start of a thread with some amazing videos on #Camouflage.

I like this one. 🙂

#cats #pets

2. But predators use camouflage too.

The striated frogfish (Antennarius striatus) walks the seafloor right up to its unsuspecting prey.

It has a prognathous mouth that launches an attack on prey in as fast as 6 milliseconds.
