I bought the (usually overpriced) loss-damage waiver in the explicit knowledge that I'd be at risk of to kea damage up there. Fortunately, they spared my vehicle.

Carl T. Bergstrom @carlbergstrom.com · 2d

And that's a superb shot of one.

Carl T. Bergstrom @carlbergstrom.com · 2d

Oh delightful!

Carl T. Bergstrom @carlbergstrom.com · 2d

Such an extraordinarily beautiful youngster 🪶

Did someone say steezy?

Kea getting steezy af, sliding down a railing on the upper leg, wings tucked in just because it can.

Carl T. Bergstrom @carlbergstrom.com · 2d

Yes! Down on Ulva; pictures forthcoming.

Carl T. Bergstrom @carlbergstrom.com · 2d

Behind every warning sign is a f'n great story.

Steezy backslide grind

Kea slipping down a metal roof, lower leg raised and corresponding wing out for balance.

This is a separate building from the one shown; I had lunch at the latter today. Detail from the interior.

Carl T. Bergstrom @carlbergstrom.com · 2d

I'll give you exactly one guess what happened to those two branches directly above the kea's head.

Carl T. Bergstrom @carlbergstrom.com · 2d

As Jesus would have wanted.

Massive notice just below the steeple bell of a white clapboard church:

PUBLIC NOTICE: ABSOLUTION NO A CLASS DRUGS WILL BE TOLERATED HERE. NO EXCEPTIONS.

Hundred percent. This just happened to be showing in the pub where I was at and I appreciated the fact that it was filmed on a circa 2002 Sony Digicam.

Carl T. Bergstrom @carlbergstrom.com · 2d

You're much too kind—but I can say that it was a very enjoyable visit, from the first meeting to the final round at the Staff Club. Thank you so much.

That's the cutest thing I've ever heard about oystercatchers.

For some reason, the TV at this hostel sucks.

Kea happily destroying the cable from the satellite dish even though it has already been kea-proofed.

Carl T. Bergstrom @carlbergstrom.com · 3d

That's a good NZ accent.

Carl T. Bergstrom @carlbergstrom.com · 3d

Kea! 🪶

Carl T. Bergstrom @carlbergstrom.com · 3d

Just on a three-week trip. But it's delightful!

I really enjoyed this interview with Mihingarangi Forbes. In 20 minutes we managed to touch on numerous issues relating to how AI is changing society, issues I've been grappling daily in conversations with colleagues here in New Zealand.

"Nothing like this has existed before, and we don't quite know what it does to people."
