Back when Tõnn was in Germany - a DNA sample was taken!!
Did we ever hear the results of that - is he a pure Greater Spotted? - or a mixture?? :D

Blood sample was taken of Tõnn - he is pure Greater Spotted Eagle (GSE) (by the methodology, Ülo has elaborated about DNA markers for to determine species of spotted eagles). It was alone pure juvenile GSE in Estonia we sampled...

Has anybody heard about storm on the Spanish eastern coast? It was probably in Tõnns place, situated not far from coast (Costa Blanca)...

There seems to be more information of Tõnn - they know it well:

http://rarebirdspain.blogspot.com/2008/ ... tonia.html

4.12. 2008. Estonian Spotted Eagle (Aquila clanga) overwintering in Spain. A satellite radio-tracked Greater Spotted Eagle (named Tõnn) has entered Spain through Catalonia, then travelled South to the Mancha area and back to the coast at Murcia, where it remained by late November 2008. According to ringers, the area is not suitable for the overwintering of the bird so it may move further along the coast. There is more information in English in the original looduskalender.ee website post above. Thanks to Gunter de Smet for the information.

There is more fresh new about Tõnn on the page tha Kotkaklubi posted. Google translator does not accept me (it gives me notice that 'you have virus!!? or something) to use translator. So if someone else can translate the page. There is better picture of Tõnn, other pictures of the eucalytustrees and landscapes where it is. They tell that it is very easy to observate from the highway..for example when sleeping on an eucalyptustree..etc

http://rarebirdspain.blogspot.com/2009/ ... en-el.html

hm.. I tried to use BabelFish, but does not work properly.. :puzzled: the map is missing??

http://babelfish.yahoo.com/translate_ur ... =Translate

But anyway, this is very funny. They know lots of the circumstancies of Tõnn there in el Hondo wetlands. (babelFish translates the word el Hondo to 'the Depth!..it should be el Hondo of course :D (spanish el Hondo means 'Depth')

These lines were in English on the spanish page: "Abstract: Greater Spotted Eagle Tõnn overwinters at El Hondo, Alicante. The satellite-tracked Estonian Greater Spotted Eagle Tõnn has been seen at El Hondo reservoir, Alicante at least since late December 2008 and into January 2009 (last seen on the 2nd). The bird is in a rich wetland which is however closed to the public and to scientifics as well due to problems between the administration and owners. This fact is difficulting any bird monitoring in the area, including the Eagle control, which however can be seen rather easily from the limits of the protected area.

And Leonia tells about an article about Tõnn in the German journal Falke (Winter Feeding Ground Cameras, viewtopic.php?f=9&t=25&p=5273#p5273)

Hi, Renandeli - you beat me to it!
For some reason or other 3 latest posts didn't show up when I checked the topic.

Mobbing: Renandelis post 3 Jan. about Tõnn in El Hondo - Spanish text says he is easy to find, native eagles & co. won't let him alone
And, Renandeli, Finland is the only place in Scandinavia (and Estonia) to have Der Falke in a library (Helsinki/Viikki & Oulu University)

Korrekted Version:

Dear Liis, your are partly right: "Schicksal" means fate, but in this case it doesn't mean anything about mobbing, only about his travel and the place he is staying now (adventure would sound less dramatic). We will try to post the article as soon as possible (may be tomorrow), Greetings, Leonia :wave:

Best wishes & catches to Tõnn, today ...
" ... Tõnn (corruption of St. Anthony, the patron saint of pigs), whose bushel (tõnnivakk) was either kept in the pantry or in the sacred grove. In Vändra in the county of Pärnumaa , Tõnn was the patron saint of all of agriculture. Offering to the household fairy began to be associated with 17 January (the feast of St. Anthony, or Tõnisepäev) . In southern Estonia half a pig`s head was consumed on this day. "
From HERE - Google cache, original seems to have gone away
The weather around El Hondo is quite nice - compared to the eagle-watchers' hideout - + 11/+14 C, a bit cloudy

Last data transmission for Tõnn was at Saturday.
Tõnn is still in El Hondo wetlands. During last two weeks there were two flights further outside of El Hondo Park, like investigating other wetlands -to the north and to the south-west direction. But most locations are as perching sites in northern part of El Hondo.

We are grateful to the editorial staff of Der Falke, for their permission to translate and reproduce here, that article about Tõnn travelling through France, Germany and then to Spain.

The fate of the young male spotted eagle Tonn

Young spotted eagle 1st year of life.

Map: http://www.looduskalender.ee/en/node/2046


A young male spotted eagle named Tonn equipped in Estonia with satellite transmitter has, unnoticed, crossed via Germany to France in October (DER FALKE 2008, H. 12). There the contact with the bird was temporarily interrupted. As planned the transmitter signal switched to his winter program on 21 November 2008, which means that information will be transmitted only every ten days. Then on 28 November 2008 the place Tonn stayed could accurately be determined. The bird meanwhile stays in the southern province of Murcia near Torre Pacheco. The landscape there is characterized with relative drought and intensive agriculture of melon cultivation and crops in greenhouses. This is certainly not the ideal habitat for a spotted eagle.

The further migration of the young male spotted eagle Tonn can be followed via Internet at http://www.looduskalender.ee/en/node/2046. If nothing will fail, the bird will start his remigration to Estonia in early spring and is expected to fly via Germany again. If bird-watchers are successfully observing or even able to take pictures, please give the information to the editorial staff of DER FALKE.

---------------------------------------

We have asked the expert Prof. Dr. Bernd-Ulrich Meyburg, Chairman of the Worldwide Research Group on Raptors and Owls e. V./Weltarbeitsgruppe für Greifvögel und Eulen e. V. (http://www.Raptor-research.de, http://www.raptors-international.de) to explain the behavior of the young male spotted eagle Tonn a bit more precisely and to try a forecast, whether and when the bird will migrate via Germany.

THE FALKE: How is the situation of the spotted eagle in Germany? Is the spotted eagle nesting here?


B.-U. Meyburg: No, the only mixed pair consisting of a female spotted eagle and one male lesser spotted eagle does not exist anymore since 2007. A hybrid nestling of this pair was fitted with a transmitter a few years ago. Currently, there are perhaps one-two hybrid females, which hatch in Germany; but the results of DNA analysis is still outstanding.

How many spotted eagles are crossing Germany during their migration to the wintering areas and how many successful observations are made by German ornithologists?

The number can only be estimated, but one may suppose that most, if not all spotted eagles, that are wintering in Spain, France and Switzerland migrate via Germany (in the last few years there has only been one case of bird in the area of Berne in Switzerland, but not yet anymore). The numbers of wintering birds in Spain and France are fairly well documented. It is not yet clear, if spotted eagles wintering in Italy are migrating via Germany. There are also many hybrid birds existing.

Could it be that there are much more spotted eagles flying across Germany, but are recognized as lesser spotted eagle?
Yes, that could be.

What are the main wintering areas of spotted eagles?
The transmitter-fitted spotted eagles from Poland are wintering in an area from Greece via Turkey to the Sudan and even Zambia. Spotted Eagles nesting further east are wintering further east, for example from India to Japan.

Spain does not belong to the main wintering areas of this species of eagle? Why is a young spotted eagle from Estonia wintering in southern parts of Spain?

Spotted eagles regularly are wintering in Spain, in Italy too for example.

Would you dare to predict whether the bird will remain in Southern Spain or will it continue the migration?

Maybe he will stay in Spain. We have fitted with a transmitter a young eagle, hatched by a probably hybrid female and a male lesser spotted eagle in Mecklenburg-Vorpommern, who currently is wintering in Cote d’Ivoire (Western Africa).

How long will the young male spotted eagle stop in southwestern Europe?
Probably until March. Young eagles can also stay longer in the wintering areas.

Do you expect the bird will cross Germany on his way to Estonia again?
Probably yes.

When will the bird probably be expected to cross Germany again?
In March.

Falke: If the young spotted eagle should again migrate via Germany and be observed there, where would such an evidence most likely made public? There will be transmitted data. Only a small part of the transmitter-fitted animals has really been observed visually.

Prof. Meyburg, thank you for this interview!

-------------------------------------

What does the rarity commissions say?

Caused by the unnoticed migration of the transmitter-fitted young male spotted eagle Tonn via Germany, we have asked the Commissions for Rare Species (Seltenheitskommissionen) of Germany, Austria and Switzerland, how they deal with such evidences.

The questions were:

(1) How often does it happen that transmitter-fitted birds fly across Germany / Austria / Switzerland without confirmed visual observations?

(2) Will evidence of transmitter-fitted birds be recognized, even when there are no visual observations available?

(3) Have there been any examples of "initial evidence" of transmitter-fitted birds in Germany / Austria / Switzerland?

Here are the answers:

Peter Barthel, Germany

(1) Certainly very often, since such an incredible number of birds are already equipped with satellite transmitters, also including common species such as storks and geese. Sometimes transmitter-fitted birds are observed without any knowledge of the observer, where the animal is originated. One is not always checking the large number of international websites for more or less actual reports about transmitter-fitted birds. In addition, many modest scientists are not interested in permanently reporting everyone about actual habitats of transmitter-fitted birds – first of all they are satisfied to receive the data from the satellite and to publish serious evaluations afterwards. Ornithological research must not ask for current sensations. It is likely that the majority of transmitter-fitted birds are not seen or not recognized as being fitted with transmitters. The advantage of this method is precisely that it is no longer necessary for observation, to be able to recognize a ring number or its colour for example! Looking only at the national observation list entries of the German Commission for Rare Species (Deutsche Seltenheitskommission) it can be determined by previous knowledge, that such cases are extremely rare. One of the few examples is an imperial eagle carrying a transmitter in Hungary, roaming in the area of Hamburg and Schleswig-Holstein in July of 2006 without being observed by bird-watchers. Even though there were people organizing searches because they wanted to add an imperial eagle to their national observation list – the bird was known as wild and not to be escaped anywhere – but they remained unsuccessful. In this respect the current case of the spotted eagle is also comparable.
(2) Of course they are recognized. After all, they are based on safer documentation than by visual observation . . .
(2) No, and besides this is hardly to be expected, if you take a look at the current range of transmitter-fitted species and the long list of about 510 already established species in Germany. Even the spotted eagle is not an extreme rarity, but even breeding in Germany. Nevertheless, it would be very gratifying to get clear evidence about special rare species out of the Pannonian area by satellite data – for example about saker falcons, because many German observations relate to probable hybrid and escaped birds.


Johannes Laber, Austria

(1) There has only been one comparable case (imperial eagle in Styria).
(2) Yes.
(3) No. Perhaps more on concrete evidence of the imperial eagle via satellite: only evidence outside of known breeding and wintering areas must be reported and dealt by the Commission – hence the Avifaunistic Commission Austria/Avifaunistische Kommission Österreich (FIU) dealt only the Styrian evidence; but there are further evidences of transmitter-fitted imperial eagle in Lower Austria and Burgenland, but those are not notifiable!


Peter Knaus, Switzerland

(1) As I know this has only occurred once: In September 1997 a transmitter-fitted black stork crossed Switzerland without being observed. I included this evidence into the book "Birds of Switzerland" from 2007 too (P. 122). I could well imagine that this occurs more often. Better knowledge may probably have the Swiss Central Marking Station/Schweizer Beringungszentrale (ring@vogelwarte.ch).
(2) Previously, there was no evidence on transmitter-equipped rarities. But I could very well imagine a recognition for the following reason: From 25.-27.11.1996 a spotted eagle was observed and documented with photos at Büsingen (Germany). As it is known Büsingen is an enclave east of Schaffhausen. The bird has been seen only in Germany, but inevitably must have crossed Swiss territory as well. The evidence was therefore recognized and also published in the book "Birds of Switzerland" (P. 226).
(3) No.


We most warmly thank the representatives of the Commissions for Rare Species (Seltenheitskommissionen) from Germany, Austria and Switzerland for their clear and very prompt responses.
