Someone asked about crows “anting” so let me quickly explain that one.
Anting is when crows and other birds sit near or on ant hills and catch ants and rub them on their feathers.
Why birds ant is still something of a mystery. We know a couple key things though: the behavior ticks up during molting season and they tend to choose ants that release formic acid.
So our best guesses right now is that the formic acid acts as an anti-parasite and/or it actually soothes irritated skin during the molting process.
So there you have it. “Ant” is officially a noun and a verb. 📸 Deborah Jones

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.

Poor little CAJA are always the last to sell. I suspect that means more people need to know about these wonderful birds. Here are my 5 favorite things:
Their baby faces are a likely byproduct of the fact they don’t do much probing in the ground like other corvids. Instead they make sticky saliva and glue extra food to trees corvidresearch.blog/2018/10/19/you…
They more regularly carry food with their feet relative to other corvids. I once saw one make off with an entire slice of bread betwixt its toes!

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.

Someone asked “Why do some British people not like Donald Trump?”
Nate White, an articulate & witty writer from England wrote this magnificent response:
“A few things spring to mind. Trump lacks certain qualities which the British traditionally esteem. For instance, he has no (1)
class, no charm, no coolness, no credibility, no compassion, no wit, no warmth, no wisdom, no subtlety, no sensitivity, no self-awareness, no humility, no honour & no grace -all qualities, funnily enough, w/ which his predecessor Mr. Obama was generously blessed. So for us, (2)
the stark contrast does rather throw Trump’s limitations into embarrassingly sharp relief.
Plus, we like to laugh. & while Trump may be laughable, he has never once sad anything wry, witty or even faintly amusing-not once, ever. I don’t say that rhetorically, I mean it quite (3)

Someone asked me if I had any advice for people building portfolios, and I'm not one to keep that type of thing private, so here we goooooooooo!

THREAD
So! There are a few things to keep in mind when building a portfolio.

First is content:

Only keep your best work in your portfolio. This means that if you have something you're kinda iffy on, DEFINITELY get rid of it.
It's okay, especially starting out as a student, to only have a handful of good things in your portfolio. In fact, it's actually preferable, because it keeps things from being cluttered or unfocused.

In general, be absolutely merciless when cutting content from your portfolio.

One thing I used to do very well is spot trends very early.
I started noticing email addresses on people’s business cards and told people that business email will become BIG! This was shortly before Lotus Notes and Microsoft Exchange became big. I also saw the cloud coming there
We were probably amongst the first to use Google’s cloud suite long before anyone in Africa and got 200 email accounts free. Swifta still has those free corporate emails till today even though they are now a Google partner selling the same thing to others. The cloud worked better
I was also the one to tell my guys to ditch our partnership with Oracle and go full steam ahead with Google because of the cloud. I remember telling someone from Oracle who was in charge of virtual machines on a flight from Morocco to the UK that they would lose Africa.

 Someone asked me recently what resources I’d recommend for furthering one’s introduction to Bayesian statistics after going through @rlmcelreath's text (xcelab.net/rm/statistical…) and my accompanying project (bookdown.org/connect/#/apps…).

Here are my thoughts:
2/n
 It probably goes without saying, but just in case you missed it, make sure you check out McElreath’s lectures on his text, too youtube.com/channel/UCNJK6…. He has three semester’s worth and they’re overall really great.
3/n
 And plus, I also like his sand-alone lecture on “Bayesian Statistics without Frequentist Language” . It’s more conceptual than applied, but we could all probably do with a little more philosophy of statistics in our lives.

We are loaded up for the @theValentineRVA’s Monumental bus tour! Let’s start with context of demographics. Approximately 40-45 people on board. I see about 3 people who are under 50 (2 of them is). Majority of bus is white. Approx. 3 people of color. #MonumentalRVA 🧜🏻‍♀️
Tour guide states they will talk about history of monuments and context they went up in. Clear there will be no debates about what should happen to the monuments. #MonumentalRVA 🧜🏻‍♀️

Someone asked my about Options trading, risks, losses and assurances:
Remember Clearly: In markets, there are NO GUARANTEES. Period..
There are probabilities and expectations.
Often Expectations are belied and this can lead to disappointment
When we all trade in Options, let's first recognize the risks.
Your putting money or handing over money is assumed to be with full appreciation of the risk involved.
Analyse the risk involved.Work out, based on available public records, what can happen..
..in case market reacts opposite your existing positions.
Whether your existing capital can hold as defence against possible losses?
Don't blame brokers or your Account Managers(If you have entrusted your trading to someone)
Blame yourself for inadequacy of capital
