Looking back and looking forward

First, looking back to a couple of aspects of UV’s “Tour of Africa” in which he travelled several hundred km further than the whole migration journey back to the UK of Rutland Osprey Project’s 30(05) who overwinters not far south of the Langue de Barbarie.

Paul has created a ‘day-by-day’ animation of UV’s African leg of his migration which brings home his powers of endurance crossing desert and mountains.

playPaul also wrote a piece for a FaceBook Osprey Group about UV’s sea crossing. It is reproduced here. Circle of Uncertainty

A final look back at that incredible journey.

Looking forward, Paul produced this earlier today:-

UV’s personal weather forecast for the next 24 hours…

Intense low W Finisterre 983mb, slow-moving, will bring rain to all areas Portugal, Spain, S France: regular showers, locally heavy. Winds mainly S to SW, light to moderate 2-4 but locally squally 5-7 ahead of rain showers. Visibility good to moderate, locally poor in rain. Outlook for Mon-Tues: more of the same.

The NASA EOSDIS satellite imagery today shows plenty of cloud.

    Thanks Joanna and Paul for yet another interesting and informative blog. UV has certainly had an extraordinary migration.

    A question for anyone who feels they might have the answer!? Do the Earth’s magnetic fields steer these birds? Sally

    Wonderfully amazing . According to BTO there is a small amount of magnetic sensitive material located in a bird’s brain which is how it can sense the magnetic lines in the earth and also birds can see polarised light even on a cloudy day and always know the exact position of the sun. Nature is truly a miracle.

  4. The BTO might need to go back to school. There is as yet no conclusive experimental proof that birds can detect polarized light, nor any demonstrated mechanism by which they might do so. Even so, this claim is often made on the Internet and the BBC – probably due to confusion between “polarized light” and “ultraviolet light”. (Which they CAN see.) Most migrant birds require a sight of the sun’s disc to navigate, although a general sense of its position suffices for most purposes. For example, an error in judging the sun’s position by 30 minutes of arc (in other words, quite a lot) would only cause the bird’s navigational sense of its OWN location to be out by around 12 km.
