The 4K Blu Ray will be released on 5th December to buy.

That's the HD Blu Ray. A 4K Blu Ray is yet to be announced.

Looking forward to Sunday nights next programme.

I bloody love nature.......in all its beauty, its cruelty and its wonder.

Amazing! Thank you BBC.

4K Blu-ray Smart players are already in the shops and include models by Panasonic & Samsung.

I have also read reports that 4K BBC iPlayer will also be launched next year before any dedicated BBC TV channel.

Agreed

Love the marine iguana's chewing on the sea bed.

I agree. I have 3 older female relatives/ friends whom can't be bothered 'learning' the HD channel numbers and if they accidentally get to a HD channel, can't see any difference in PQ. One relative sits within 4 feet of a 7 year old 50" Panasonic Plasma watching very very 'noisy' Freeview SD picks rather than turning on her TiVo HD box which she uses for the occasional recording ( in SD of course)).

Snakes.

Run Forest, Run!

Wow that's the first time I've seen something like that. No wonder they call snakes evil.
Ganging up on the lizards like that.

Poor little iguanas have to learn to run straight away.

That red crab leaping at the screen made me jump, glad it's not in 3D.

Watching it again, so good.

Me too

You miss bits first time, enjoying it x 2.

Me too. The natural world is amazing and mindblowing. Attenborough's programmes are always fantastic.

Gawd, this reminds me a bit of those chicks who throw themselves off the side of a cliff!

Go go lil ibex!

Wow!

Go ibex - how cool are they?

I don't want any of them to get caught.

Amazing how the Ibex can cling to the side of the mountain and run around on it

The fox is quite cute too, but glad they got away

Those Ibex are amazing

This all looks very Lord of the Rings.

How do they fix a camera to that eagle?

Clothes peg.

WWE. World Wrestling Eagles.
