Ceulan started his migration on Monday morning (September 3rd), by Saturday evening he was in Africa. I just can't believe I've just written that.

Here's a video of him leaving the Dyfi on that Monday morning - he circled his nest a few times, gaining height at each orbit, until he felt he was high enough for the start of his long journey. Then he was gone..

The last blog a few days ago had Ceulan just south of Porto, Portugal - he didn't stay there long. By midday September 7th, Ceulan was in Lisbon and by early evening he had undertaken a short, 110 mile trans-atlantic flight to the Algarve, where he roosted for the night.

At around 09:30 the following day, Ceulan left Portuguese airspace heading south, straight over the Atlantic ocean once again. 12 hours later that evening at around 21:30, he was in Africa. He made landfall 38 miles west of Casablanca, Morocco.

(Please be aware of some of the speed readings reported on Google Earth: Many are in the 16/17 Kph range which is only 10 mph. The Portugal-to-Morocco ocean crossing took Ceulan 12 hours, and the flight is 260 miles. That corresponds to an average flying speed of around 22 mph, which is much more realistic. 22mph corresponds to around 35 Kph - around double that recorded by the tracker data. The actual speed would be slightly higher still, as Ceulan does not fly in perfect straight lines between points, of course. I don't know why this is, but we have to remember that this is still fairly new technology and not every reading is spot on, the positional GPS location readings are, however.)

Ceulan roosted for the night by the Moroccan coast, but the following morning, September 9th, he was off again. By lunchtime, he was 40 miles further south and crossed the same path that his brother Einion did last year. Einion was in the same place at the same time on the same day - September 9th. They were so close, they would have seen each other in a one-year time machine.

Since crossing Einion's trajectory of 2011, Ceulan has mirrored his brother's flight south. He roosted last night (September 9th) just north of Agadir, Morocco, before starting first thing this morning again. The last point we have for him is from 18:00 tonight (September 10th) on the northern Mauritania border, well south of the Canary Islands longitude. Ceulan is now less than 900 miles from the Gambia.

As I write on Monday evening, it's almost unthinkable that Ceulan only set off the previous Monday. He's travelled over 2,000 miles in that time, at an average of around 300 miles per day. Ceulan left a wet and windy Wales just a week ago and is now over the largest desert on the planet - the Sahara. Insanely amazing.

If Carlsberg did ospreys, they'd make Ceulan.
