The adult eagle is at the nest site

The adult SSE fitted last year with PTT(0)82163 has reached its nest site after some ice-hopping. It was evidently traveling along the open water clearly visible in the MODIS satellite image above. It travelled the length of the Sea of Okhotsk in 4 days!

Youngser went North

After a minor problem with Argos data flow the missing data have been received. It looks like the youngster (PTT5629) left Hokkaido on 4 April 2010 and is now on Sakhalin Island.
The adult female is ice-hopping sowewhat North of Shantar Island.
More data to follow. Fingers crossed.

First eagles at the Balagannoe

Meanwhile the first adult Steller's have arrived at Balagannoe in our study area on 6 April 2010. Photos by Olga Mochalova

Adult eagle is ice hopping

Since 18 March our adult eagle has been living on the ice, ice hopping at least until 22 March. Meanwhile, the Argos system started adding a "0" in front of the PTT numbers. Hope our automatic system will not loose any data.

The youngster PTT62629 is not sending good signals. The battery probably is approaching the end of its life. There are some fairly low quality signals indicating that the bird started its migration on 18 March, but no more reliable GPS fixes... The last doppler fix was on 23 March.
