C’est mercredi soir, l’heure de #crowOrNo ! Le but, deviner si l’oiseau présenté est une corneille (crow) ou pas.
Corrigé : c'était bien une corneille, notre bonne vieille Corneille noire. Dans l'ordre de fiabilité des critères de départage, selon moi :
1. les plumes du cou ("hackles"), très développées chez le Corbeau, ce qui n'est pas le cas ici.
1. les plumes du cou ("hackles"), très développées chez le Corbeau, ce qui n'est pas le cas ici.
Beaucoup d'Américains se sont fait avoir par ce critère parce que leurs corneilles ont des hackles très peu visibles. Mais la comparaison Grand Corbeau (à gauche) vs Bob faisant ses meilleurs efforts (à droite) est sans appel.
Différencier Grand Corbeau (Corvus corax) et Corneille noire (Corvus corone), un court thread.
⚠️ « corbeau » en langage courant est un terme ambigu pour les corvidés noirs (Grand Corbeau, Corbeau freux, Corneille noire, moins couramment Choucas des tours)
⚠️ « corbeau » en langage courant est un terme ambigu pour les corvidés noirs (Grand Corbeau, Corbeau freux, Corneille noire, moins couramment Choucas des tours)
Critères :
- taille : 120-150cm d'envergure et 1,5kg max pour le corbeau, 95-105cm et 600g max pour la corneille
- bec : massif chez le corbeau (forme de couteau Bowie), plus effilé chez la corneille
- ailes : plumes du bout de l'aile bien distinctes (digitées), battements lents
- taille : 120-150cm d'envergure et 1,5kg max pour le corbeau, 95-105cm et 600g max pour la corneille
- bec : massif chez le corbeau (forme de couteau Bowie), plus effilé chez la corneille
- ailes : plumes du bout de l'aile bien distinctes (digitées), battements lents
Concrètement : un Grand Corbeau c'est *énorme*, pas loin de la taille d'une buse variable. Critère parfois difficile à apprécier de loin, en vol, faute de point de repère. De près, ça ne se loupe pas.
Oh haiyyy, it’s #CrowOrNo time my friends. That means you tell me if this bird is a crow (has the word crow in its common name) or no and at 5:30PST I’ll tell if you were right and offer some ID tips. Good luck and if you like the game give it a RT!
Alright folks, ready for this week’s answer? This bird is #NoCrow! As many of you guessed it’s a common raven!
Although this week’s main clue was subtle, once you know it, it’s a great subjective field mark to keep in your back pocket. Ready for it? Ok see these “horns”? That’s a raven thing. Crows don’t articulate their feathers like that.
It’s that time again folks! You gotta decide if this lil hitchhiker is #CrowOrNo. Looking forward to your answers! I’ll be back with mine at ~5:30 PST. Good luck! 📸 Birch Rostholder-Harris
TERRIFIC job today folks! Most of you have rightly guessed that today’s #CrowOrNo is no crow. It’s a jackdaw, Corvus monedula)! Also in the picture is a red deer, a native to Scotland where this photo was taken.
The clues today varied from beginner level to more advanced. At the beginner level we had the overall coloring and iris color. Now of course not all crows are exclusively black, and not all have brown/dark eyes, but the particular color patterns on this individual are unique.
Welcome to another round of #CrowOrNo! Normally I don’t tell you who the contestant is but today I’m just going to come right out with it...it’s Bob. Hope that helps! Answer at 5:30 PST! 📸@Jastrow75
Alright Bob, it’s time to find out if you’re a #CrowOrNo! Ready??? Bob is a crow!!! A carrion crow to be precise, which are one of my favorite for this game. Why? Because they’re damn tough!
I mean look at those throat feathers! If you’ve been paying any attention to me you might suspect those be be hackles a la a common raven and I COULD NOT BLAME YOU
Woohoo this week’s #CrowOrNo challenge has officially dropped! Will you be victorious this week? Only one way to find out! Give it your best shot and if you’re feeling up for it post your answer in the comments. All skill levels welcome. Answer at 5:30PST! 🍀
Wow wow wow, lots of #CrowOrNo players this week and-spoiler alert but not really because it’s answer time-most of them were correct! That’s right folk’s this week’s challenge was a raven!
Specifically this is a common raven I photographed in @DenaliNPS last month. This is a male that was standing guard while its mate incubated eggs nearby.
This week’s challenge was submitted by @/mjerniganart on IG who, side-note, is a talented natural history artist and a worthy follow. So who is this curious corvid? #CrowOrNo? Excited for your answers!
Oh boy folks, you ready for this week’s answer? Today’s photo challenge is 🥁🥁🥁 a crow! As the photo was taken in Florida, I can’t tell you which species. IDing the difference between the two species there (American crow and fish crow) is not a skill I have for a pic like this
Generally fish crow (Corvus ossifragus) are smaller than American crows. Though they really have to be side by side for most people, even experts to notice the difference. The biggest help is the voice, with fish crows producing nasally calls.
Today’s #CrowOrNo photo was the recent source of contention for an online birding group. Will #CrowOrNo players likewise be split, or form a clear consensus? I guess we will find out! Answer at 5:40. Good luck! 📸@/photothatmatt on IG
This kind of photo is my favorite kind of #CrowOrNo challenge because it’s inexplicably hard. You have a lot of info and yet you’re just not ~quite~ sure. I second guessed myself too at first. But after some hemming and cawing I landed on #Crow!
How do I know? The proportion of the bill, the proportion of the nasal feathers on the bill and the texture of the throat feathers.
Today’s contestant may be slightly disappointed this garbage can is empty but it’s really thrilled you’ve joined for another round of #CrowOrNo. Share your answer by 5:30 and RT for good luck 🤣
Whoops looks like I’m a little late today! I got distracted by a very sexy dude that was putting the moves on. But I’ve sorted myself and am ready for the big reveal!
Well @FalseKnees your reputation can rest easy because today’s #CrowOrNo was a crow! A carrion crow as some of you guessed.
It’s #CrowOrNo day!!! This week’s rather ~moody~ challenge comes from @CocktailMD. What did they see during their special trip? Looking forward to your answers!
NICELY DONE, TWITTER! Today’s #CrowOrNo contestant is most definitely a very wet raven. Mary Berry would likely not approve.
So what were the secrets this week? Although the wet feathers throw the texture a little, the hackles are still quite evident. And even at this angle the size and shape of the bill screams raven.
Ya’ll ready for this week’s #CrowOrNo? Today’s bird comes with a number of markers that offer helpful clues. The question is if you spot them. Good luck! Answer and photo credit at 5:30.
Sorry I’m a little late, folks! Was arguing about whether coyotes deserve to be killed by the hundreds for fun times (no, uh, they don’t.). ANYWAY...this week’s #CrowOrNo is 🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁
Not a crow! Not even a corvid! And so many of you got this question ~currawright~ that I think I might need to up my game. Like last week the trick was nasal bristles and can I say that I LOVE when you point these things out in your answers because I 100% do.
⚠️It’s Wednesday so you know what that means...#CrowOrNo time!!! 🎉 What will be your guess today? I can’t wait to find out! Answer at around 5:30PST. #crow #scicommgame
Well if I thought there was ani chance of fooling you I was sure wrong! Most everyone nailed this week’s challenge. These are neither crows nor corvids, they’re smooth-billed anis!
I captured this pair while on a trip to Costa Rice last year. The best tell that it’s not a corvid is (as may of you pointed out 🥰) the lack of nasal bristles! The long tail is also a good indicator because none of the Corvus sps have extra long tails, though many corvids do.
Yikes @Astro_Limno really wants to push your #CrowOrNo limits today! Will her photo best you? Only one way to find out! Have fun and good luck!!! Answer at around 5:30 PST
Ready folks? This week’s bird is...#nocrow! It’s a raven. What strikes me as the clear indicator is the resource size of the bill. Even so far away it really stands out. The habitat is a good confidence boost for this is too.
In s second picture that @Astro_Limno sent, the size of the bill is even more clear.
Hey guess what? It’s the best day of the week! It’s #CrowOrNo day!
Today’s challenge is brought to you by @Sciwhat. So what kind of a peeping Tom do they have here? A #CrowOrNo? Answer at 5:30 PST! Good luck!
Woof, I’m pretty late tonight, but data always takes precedent. Thanks for your patience! This week’s #CrowOrNo photo is...a crow!!!
It’s Wednesday, right? For sure? I’m not falling for this “it’s Wednesday, but not really” nonesense again today.
Ok well since it is actually a Wednesday...let’s get our #CrowOrNo on! New players: just tell me if at least one of these birds is a crow or not before 5:30ish PST. After that I post the answer and ID tips. Good luck!
You folks ready for your #CrowOrNo answer? The bird on the right is not a crow, it’s a raven! But the bird on the left is...
It’s that time again folks! From penguins to corvids, tuxedos are a popular look in the bird world. But is this particular fashionista a #CrowOrNo? I’ll post the answer around 5:30 PST, though no promises because I’m on fieldwork time 😉. Photo c/o Frans Sellies.
Nicely done folks with the amazing turn out! As most of you guessed today’s #CrowOrNo is most definitely a crow! An African pied crow to be precise.
You can distinguish pied crows from magpies by the heavier bill and thicker rictal bristles (nasal feathers) on the crow. Probably the best tell though is the hackle like throat feathers on a pied crow.
Welcome new followers! Are you ready to play one of the most fun #Scicomm games on Twitter??? Well get ready, because #CrowOrNo is here and ready to knock your socks off
How does #CrowOrNo work? Every Wednesday at about 11:30am PST I’ll post a photo of a bird. It’s up to you to decide if it’s a crow or not.
In this game, a correct crow answer constitutes any bird that has the word crow in its recognized common name (what you’d find in a field guide).
Yesterday I defended my thesis & become Dr. Kaeli Swift. For a little girl who couldn’t read until she was 8, who for so long thought she was doomed to academic failure, this is a huge moment. 2nd person & 1st woman in my family to boot. I’m really fucking proud of myself.
Wow. Just wow. The outpouring of support here has kind of blown me away. Thank you all so, so much.
I have to say in some ways finishing my grad program is bitter sweet. Sweet for your obvious reasons, but bitter because, well, I freaking love crows and I want to study them forever!
After several weeks (well, years) of work my dissertation has been submitted to my committee. No telling what they’ll say, but while I sweat that out I think it’s only fair that you grapple with your own crow struggles. In other words... #CrowOrNo is officially back!
With it being 90* here in Seattle, I think this rather hot bird is a fitting photo for today’s #CrowOrNo. The question is...is it a #HotCrow or a #HotNo? Answer at 5:30PST
Wooohoo thanks for playing everyone! This week’s #CrowOrNo is 🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁a crow!!! A carrion crow to be precise.
