 Fiskgusen 2009

15-16 augusti 2008
En av de fiskgjusar som forskarna vid Lunds Universitet och Grimsö forskningsstation följer med radiosändare passerade nordvästra Skåne på sin väg till västra Afrika den 16 augusti.

Gjusen, som är en hane, började sin flyttning från Grimsö den 15 augusti. Han har tidigare övervintrat i Saint Louis i Senegal och är förmodligen på väg dit nu också.

Starka ostvindar har medfört att han i år tagit en mer västlig flyttväg och han passerade Helsingborg och Ven vid lunchtid i lördags (ca 10.30 GMT).

Allt enligt meddelande från Raymond Klaasen (forskare vid Universitet i Lund) via Håkan Karlsson.

Raymond Klaasen rapporterar att fiskgjusen nu har kommit till nordöstra Frankrike. Där har han stannat till även vid sina tidigare flyttningar.

Han njuter nu av utsökt fransk fisk som han (se kartan nedan) fångar i flera olika sjöar.

The 'Helsinborg-male' is still at his stopover site in France, somethimes moving around (short trips to nearby lakes) but mostly chewing and digesting fish.

Such long stopover in Europe is quite common among Swedish Ospreys. I think that they are moulting some flight feathers, taking advantage of these food rich areas, and possibly prepare for the Sahara crossing (some fattening up might go on).

Last two years this male spend about 25 days here, thus we have to be even more patient to see the last part of his autumn travel...

Mer information från Raymond Klaasen:

Finally the boy is on the move again. He has just left the stopover site and is now facing the pyrenees (see map).

One thing we are wondering about is whether he is going to make a detour in the Sahara, just as he did last two years... to be continued...

Ny information från "vår" fiskgjuse och Raymond Klaasen:

Our osprey has now crossed both the Pyrenees and the Mediterranean Sea. The latter he did in a typical way for soaring raptors. The last position in Spain was at an altitude of 1515 meters. He apparently glided down from there because following heights for the locations above the sea are 0, 74 and 61 meters. They thus fly really low when crossing that water! Latest positions come from Morocco.

I expect the male to arrive at his wintering area rather soon now.

Ny information från Raymond Klaasen:

Fiskgjusen är på plats!

The male has had no hesitation crossing the Sahara Desert this year. Without detour he directly flew to his wintering site in the outskirts of Saint-Louis in Senegal.

This shallow lake is like a waste dump for the city, but the Osprey seems to like it as he has now returned here for the third year. Here he will spend the winter, sitting on car wrecks and other city dirt. Occasionally he will catch a fish in the ocean.

An interesting feature you can see on the map is that the Ospreys tend to fly in curves while crossing the desert. This we cannot explain readily by effects of wind, but actually is a great mistery.

The detailed trackings provide us many answers but in the same time produce very new and exiting ideas about migrating birds that we have never though about before. Or as somebody recently said: virtually everything can be expected while you start to track birds, and it is that what makes this research so exciting.

I will not expect any interesting movements during the winter, but in case something happens I'll let you know.

Ny information från Raymond Klaasen och "vår" fiskgjuse:

Nothing much had happened at the Osprey-front. As usual the birds are sitting at their wintering site, just like the male near Saint-Louis. The whole winter the male has been sitting at this sand reef, with an occasional fishing trip to the shallow lake just next to it.

They seem to live a really easy life down there! See two pictures attached.

Now the male is hopefully preparing for his spring trip. He should by now have finished his wing moult. This is the only really important thing they have to do down there, because during the rest of the year they have no time for this.

I expect the male to start somewhere in March..

Ny information från Roine Strandberg och "vår" fiskgjuse:

Eftersom vi för tillfället inte kan göra direktimport i Google Earth får ni ta del av lite mer lågupplöst karta på fiskgjushanens vårflyttning.

Han startade förra helgen från S:t Louis i Senegal och har nu passerat Gibraltar.

Om han inte rastar, vilket han bör göra med rådande väderläge, har han en dryg vecka hem. Förra året anlände han den 7 april.

Ny information från Raymond Klaassen och "vår" fiskgjuse:

Sorry we have not been able to provide a more detailed picture about the migrating Osprey. Both me and Roine had very limited time this spring to check for positions due to field work. Also there was some problem with decoding the gps data. There are plans for an automated presentations of our raptors on the Lund University website. With some luck this will be operational before next autumn, so that everybody can ckeck the movements on a daily basis of all the birds we follow.

I have just checked the latest positions. The male from Helsinborg has used the nice weather to complete his migration. He is now already home at his nest in Grimsö, quite early in comparison to earlier seasons. After he crossed the Sahara he has rested a few days at his traditional stopover site in southern France. When the weather was nice he quickly flew north. He passed the Öresund on the second of April, somewhere late in the morning (we miss some positions that day). It is quite difficult to say where he passed exactly, but it has been at the southeast coast of Skåne.

I was in Grimsö last week. There most lakes are still frozen. The Osprey thus relies on the few steams and lakesides that are open (see third picture). He possibly might have brought some body reserves to survive these cold conditions...

Regards,

Raymond
