For #SuperbOwlSunday:
Let me introduce Ornimegalonyx oteroi, the Cuban Giant Owl, which stood up to 1.1 m high (3.6 ft) and weighed between 9 and 30 kg (20-66 lb).

It went extinct about 6,000 years ago, but during Miocene, they likely hunted mammals: seal pups, large rodents. Image
Because the Cuban Giant was probably flightless (wings too small for sustained flight), they probably were adapted to run with an assist from undersized wings, or took their buddy's sweet vintage VW Bug, as pictured here. Image
Besides pouncing on prey from rocky cliffs, they also lured food items by re-enacting that scene from Titanic, and waiting for a stupid mammal to shout : "I'm king of the world!" so they can pounce on them. Image
The Cuban Giant Owl also had poor conflict resolution skills & frequently got into fights over even most trivial of subjects.

Here a Cuban Giant resorts to fisticuffs with a Caribbean Monk Seal over boombox volume while two Emslie's Vultures decide whether to call 911. Image

Anti-mask or anti-mandate protestors see themselves as 'civil rights activists', but the more accurate comparison is to smokers' rights activists: they're fighting for the entitlement not to be inconvenienced by other people's health concerns. Image
Smokers' Rights Activists were all bankrolled by Big Tobacco, groups like National Smoker's Alliance (NSA) formed in 1993, one of the earliest examples of "astroturfing".

Much of the wording and arguments against public health are the same. Image
The difference between these "anti-public health" movements and genuine struggle for civil rights is the inherent selfishness, focusing on actions rather than identities & the meaning of "liberty". Image

The smallest extant owl is the Elf Owl, no larger than a sparrow, with mean wingspan of 30 cm (11 in) and body weight of 40 grams (1.4 oz).

The Elf Owl migrates between the US Southwest (including Texas!) in Spring/Summer & Central Mexico in Fall/Winter. Image
The elf owl hunts mostly at night, and are ferocious scorpion hunters. They carefully remove the stingers before scarfing them down, like a picky roommate removing the nasty black olives from a pizza slice. Image
The Elf Owl plays dead when handled, encouraging predators to drop them long enough to escape.

If that doesn't work, they're known to McGuyver up an escape plan using a paperclip, some steel wool, and a cigarette lighter. Image

I'm hungry: let's talk about #hotdogs.

1880's German immigrants brought a type of pork sausages, Frankfurter Würstchen, named for Frankfurt (hence 'franks') or, if mix pork/ beef, a Vienna (Wiener) Würstchen (hence "weiner").

But how did they come to be the hot dogs we know? Image
It was widely believed that disreputable street-corner sellers made them from stray dogs. Thomas Edison even made a 19024short film called "Dog Factory" showing dogs being shoved into a machine, and sausages coming out the other side.

So, a hot dog was a derogatory reference to meat contents, probably aimed at insulting the vendor... that stuck. See cartoon, if you can make it out.

So where did the bun come from? Multiple versions of story, but I'll share some. Image

Let's talk about the Ben Franklin effect:
A person who does a favor for someone else is more likely to do another favor than if they had received a favor in the initial exchange.
(thread)
It's named for a line in Ben Franklin's autobiography:
"He that has once done you a kindness will be more ready to do you another, than he whom you yourself have obliged."
There's a story about Ben Franklin and a rival legislator, where Ben won him over by requesting to borrow a rare book, returning it promptly with an effusive thank you note. Afterwards, they developed a deep friendship, and the rival became indebted to support Franklin.

I need to vent:
1. You don't need a vaccine card to go to the grocery store or "freely move about society".

2. We require licenses, proof of insurance, registration, inspection stickers, business licenses, event permits, visitor passes, etc. for any manner of venues.
3. We've required shot records for schools, some hospital wards, and we restrict visitors, enforce quarantines for international visitors, migrants and goods from other countries going back to Ellis Island.
Public health has always existed in dynamic tension with personal freedoms & the only reason that tension persists is that pandemic disease requires collective action to combat.

No-one likes it, but we do it because of what it can accomplish in the long run.

About 120 million years ago in what would become North Texas, a herd of sauropod dinosaurs, adults with their young, wandered along a coastal river delta, leaving footprints in the wet lime sediments.

At a later time, a group of theropods or carnosaurs followed the same path. Image
Silts and clay filtered in and filled the tracks, hardening into two layers of limestone & shale sediments. The Paluxy River unearthed the preserved trackways about 1 million years ago. Image
The area is now Dinosaur Valley State Park, one of the best preserved trackways from the Cretaceous. You'll need to wade out to see some of the tracks in the Paluxy, some as big across as 3 ft (1 m). Image
