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.

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.
