Summaries of WTE observations at feeding ground 2012-2013

Post by ame »

INTRODUCTION

Observations of white-tailed sea-eagles (shortened hereafter as WTE) visiting the winter feeding ground during the season 2012-2013 will be summarized under this topic. Special attention will be paid on observations of eagles carrying rings, because the special zoomable camera used at the feeding ground allows viewers to read ring codes and to take snapshots of them.

WTEs have been ringed (or banded) with two rings both bearing two coloured stripes. The colour codes are given in the picture below (by 0Hansen).
Image
Chart updated on Feb 24 2014.

The colours on the ring on the right ankle (or tarsus) show the country where the eagle was ringed. Some countries are geographically so large that they have been divided in several regions with their own colour codes. Hungary and Austria on the other hand have a common colour code. The country codes are on the left side of the above picture.

The colours on the ring on the left tarsus give the year of ringing, which is most often the year of birth of the bird. This practice was started in 1976.

An individual code is also marked on the left ring starting from 1991: on the top stripe a combination of a capital letter and a number, and on the lower a two-number code. The year codes are on the right side of the above picture.

The letter in the individual code is the same for all ringed birds in one year till 2011. The oldest eagle observed here last season was Y445 who was ringed in 2005 in Estonia. The second oldest was Z848 from Finnish Lapland, ringed in 2006. Letter V stands for year 2007. For 2008 the letter is A, for year 2009 the letter is B, for year 2010 the letter is C, for year 2011 the letter is D.

Starting from year 2012 the colour coding has altered. All the year rings on the left ankle are black and the letter shows the region of birth according to the picture below (by Bubo). After the letter there is a number and below these two other numbers which together form the individual code for each bird. The colours on the ring on the right tarsus also show the origin of the bird as before.
Image

Below is an example of an eagle which wears a white-over-red ring on the right tarsus: it was ringed in South-West Finland. On the left tarsus there's ring with black upper part and blue lower part: it was ringed in 2009. The individual code on the left ankle is the eagle's "name", B279 which allows authorized reseachers identify its home nest and other information on the eagle.
Image

Observations will occasionally (and hopefully) be commented by our eagle experts Urmas Sellis and Renno Nellis. Also other interesting observations of other animals, birds as well as mammals will be reviewed here on daily basis.

Summary of WTEs observed on the feeding ground in the season 2011-2012. IV

From the report Webcam at eagles winter feeder 2011/2012. RESULTS
Ordered by Estonian Ornithological Society
ESTLAT Eagles Cross borders project
Läänemaa 2012
by Renno Nellis.
The whole report is accessible on the webpages of the Estonian Ornithological Society through this link:
http://www.eoy.ee/sites/default/files/p ... report.pdf .

The number of observed eagles and the number of ringed individuals are shown on Fig 2. The number of all eagles was estimated according different ringed birds and different ages observed during a day. In days if there were more as 10 different birds, it was difficult to estimate the real number as several birds of the same age were presented. So the numbers are minimum. During two days also golden eagle visited the feeder. Additionally once goshawk was observed and at least three common buzzards in several days during the season.

2012 Dec 11

The winter season 2012-2013 begins: the camera was online for a while for testing. Fireblade had been keeping an eye on the link and had noticed that the transmission was on in the afternoon. He posted the first picture on the Seal camera forum while the feeding place forum was still locked.

A short test recording was also made. After some time the nõva-camera was disconnected again, after being on for at least about half an hour.

Dec 12

Estonian press noted the installation of the winter feeding camera (and the installation of the WTE nest camera at the new nest site; more of that later in the spring!).
Liis wrote:Here is an article by our favourite eagles and storks reporter, Ulvar Käärt, after having been invited to assist in the camera installation work for the eagle feeding ground and at Linda and Sulev's new nest - really hard work, too.

From newspaper Eesti Päevaleht yesterday http://www.epl.ee/news/eesti/kotka-pilg ... d=65381840
Photos and video - see in article at link above.g the webcam on your computer screen.

Liis commented Jo's message:
Liis wrote:A lot more and interesting photos, same text as in the EPL article. So if you fit that in, you have the whole in English!
EDIT: 4th photo, explanation added: no, they are not carrying the bathroom door but a solar panel.
So this was an article by Ulvar Käärt with photographs by Ilmar Saabas, the same reporters as in the article in Päevaleht, but in the Delfi link given by Jo one can watch a video and in the bottom there is a large picture gallery of the camera installation trip to both the WTE nest and to Nõva forest, where the feeding place is situated.

In this picture reporter Ulmar Käärt is holding the special camera which is used at the feeding ground.

Dec 13 - Dec 29

A long wait followed...

Renno, Urmas, Ulvar and Ilmar participated by installing of solar panels at Linda-Sulev nest site. At winter feeder there was no Renno, but Omar (dealer of Mobotix cameras in Estonia). He prepared separate audio system for feeder-cam, as zoom-tilt cameras do not have built in microphones (motor noise will disturb).
But Renno will go soon and repair the switching system, if possible. Its not so easy to say, what is real problem if the stream is missing.
... until finally!

Let's hope it will be now stream without of problems. We were with Renno on place and changed the antenna in forest also provided some additional food (a roe deer I picked up from the road near Pärnu) and other carcass (without of skin) is of wolf. There are also skins of hunted wild boars and racoon dogs, with some meat left.
Several eagles were on place, but we of course scared them away. Couple of adults were quite bold actually and did not want to fly away easily. So for tomorrow there is hopes to meet some fellows from last season or also new faces.

First WTE observed with rings on the feeding ground this season was B279 on black&blue ring on the left ankle. Black&blue mean that it was ringed in 2009 so it is a 4th winter eagle.
airras wrote:Image
White over red on the country ring tell that this eagle was ringed in Finland SW Archipelago which may include wider coastal areas, too. (Details are kept unkonown for public.) From now on this code will be shortened as SW Fin.
Fleur wrote:Image
[color=#FF8000]On 30 Dec 2012, 10:59[/color] Urmas wrote:B279 is our old fellow from Uusimaa, Finland.
He was observed during last three winters in the feeder. Also its brother A278 has been seen, but not so frequently. B278 was photographed also in April 2012 in western Estonia by Tarvo Valker.
Renno's comments on this bird:
[color=#FF8000]On 21 Jan 2012, 13:31[/color] renno wrote:This bird with ring B279 is born in 2010 somewhere in SW-Finland, most probably somewhere on Turku islands. We will forward this observation to Finnish Ringing Centre. We all saw this bird here also last winter, last time exactly year ago - 20th Jan 2011!
A few days later Renno corrected the year of ringing. (viewtopic.php?p=124794#p124794)
[color=#FF8000]24 Jan 2012, 10:36 [/color] renno wrote:This is our old friend from SW-Finland born in 2009. Few days ago I mistakenly wrote that this bird was born in 2010 but 2009 is correct year (3rd winter bird). We saw this bird last time three days ago.
B279 was a frequent visitor at the feeding ground last winter in the previous season. It was observed there altogether six times: on Jan 21 and 24, and Feb 17, 18, 19, and 20 in 2012.

Here's a map of Finland showing very roughly the areas to which the Finnish country rings refer to. Åland (red over black) is in blue ellipse and Quarken (all red) is in red ellipse. Finnish Lapland (white over black) is in green ellipse which is maybe too large or, on the other hand, the area maybe larger, somewhere above the black line. Finland SW Archipelago (white over red) may also include wider areas on the Southern and Western coasts. Finnish freshwater (red over white) means inland lakes but how far from coast the border lies is unknown. One more question mark is the bottom of the Gulf of Bothnia: does it belong to Quarken or Lapland. Geographically it belongs to neither, nor to any other of the five areas.

Bea wrote:This adult with no rings was chased away by the young one, who wants to have all for himself.
Image
The beak has still some dark colour and the tip of the tail is not white, so this is not quite adult yet. It wears 4th winter costume probably. The eyes seem to be very dark, but the lighting was so poor that it is difficult to see. The irises in the eyes may also be wide open because of the poor light level.
Later maybe the same bird in a tree.

This video shows the same three eagles again but later. The video was recorded by Fleur at 12:15 EET (which is camera time; Fleur's time is CET which is one hour late from EET. that's why the time stamp of the video is 11:14:57)
