Some people see colours coming from musical instruments when people play them. Its called sound-color synesthesia.
Could it be that the Condors see thermals and air currents in the same way and that is how they are so adept at finding them. |  |

Wait until you hear about planes, they don’t flap their wings at all. ;) |  |

Just pick a shark, turtle or whatever and see where they have been over the last few years and where they are now.

I'm sure that many years ago I read that some blind people can echo locate like bats (making clicking noises with their tongue)?
Also, with regards to your post, some savants see numbers as colours too. |  | | |

Before or after hallucinogens? |  |

That looks great, thanks. Not sure if I'm brave enough to cross-reference my PADI logbook against those tracks but! | |

Wow, you just reminded me - had forgotten about my BSAC one for the past 28 years, think the ex must have had it when we split up as he looked after all the diving gear! [Post edited 15 Jul 2020 2:52]

Bird eyes / sight is a really interesting topic.
Most birds can see UV light as well, and in lots of species where we can't easily tell the males / females apart on plumage (Blue Tits, Robins, Swallows etc.) there are patches of UV reflective feathers which are only present on males (normally) which mean the birds can easily tell if it's a male or female.
There is also a protein in birds eyes with electromagnetic properties which is likely the key to how birds navigate - we have no idea how it works (as far as I'm aware) but they will likely 'see' the Earth's magnetic field somehow.
One of my favourite ornithology experiments is where in the 1930s, a Cambridge Professor who was interested in how birds navigate went to Lundy (in Bristol Channel) and collected up some nesting adult Manx Shearwaters, put them in a car, and drove back to Cambridge, took them up to the top of a tower in the University. As seabirds, they would never have been to Cambridge before, couldn't possible know where they were, recognise landmarks etc.
He released them (with coloured rings on), and upon release they all immediately flew directly West-South-West, and about 6 hours later (his colleague on Lundy reported) they were all safely back at their nesting burrows.
It's extraordinary to try and conceive of how they could do that - until, many years later, the electromagnetic protein was discovered in bird's eyes. |  | | |

We have loads of Red Kites near us. They just glide around off the thermals, sometimes look like they're hovering. I always find birds in general a really cool animal to watch - apart from the ones in kebab shops at 2am. |  | | |

I got stuck behind a cyclist who was wasn't peddling the other day he covered about 500 yards in what seemed like an eternity |  |

Five hours without flapping - I think you have to go back to Paul Cooper to have seen that at Town... |  |

This follow up would have been better if it had occurred to me forty minutes earlier, but
I guess that was my Condor moment... | |

Turtles also use the Earth's magnetic field, to find their way to the beach they were hatched on. Something to do with coastlines having their own magnetic signature, that the Turtles somehow remember. They also use the invisible lines of the magnetic field to navigate at sea. Fascinating stuff.
