Trinus (L2 - )
On 07-02-2007 we caught Trinus near Eernewoude (Friesland, NL) and marked it with lime-green legring "2" on left leg (so code: L2 -) and equipped this bird with a satellite transmitter. Trinus weight was 2340g and he flew in a flock of 12 birds.
Up to end of March Trinus was roosting in Poland and migrated to Kostroma district in Russia. Mid of May he reached Kanin-Peninsula. End of May he was tracked on Kolguev Island.
Also end of May the news about Trinus on Kolguev came to the scientific team there and on 19th of June we tried to find Trinus there.

Trinus breeding range
On Kolguev Island you can see the results of the last ice-age. Large hilly areas with glacial lakes providing geese an attractive variety of breeding sites. In 2007 unfortunatly we had a very cold spring and so the glacial lake area was covered with snow and ice up to the middle of June. Most of the pairs paused breeding or started very late. When we came to Trinus positon we found a lot of geese there, mostly in larger flocks. In late evening thick fog came and so we had no chance to find Trinus.
On our picture you can see flocks of geese and imagine how the landscape look like.

21-11-2007 - last data
Since 26-10-2007 we did not get any good coordinates from PTT Trinus which would allow us to give you any geographical information about its position. Nevertheless, the engineering data send on 21-11-2007 looks okay. The battery is very low, but there is no mortality sign shown.
