It looks like the GPS positions of the youngster are coming from one location from January 17, 2011. The temperature of the PTT also does not look good, and is well in the negative zone. That can happen in a storm, as happen recently to the adult (on Hokkaido, on Dec, 8, 2010), but it could also be a singnal that the bird is down or the tag has been removed. Before settling at Point Balkan (or in other maps Cape Kornelia), the bird made several frantic movements around the Aniva Peninsula, and now remain at one point (orange bar on the closeup map is 50 m).
Well, I do not know what to say. Let's wait for next 10 days, perhaps the next transmission will bring more news.
Meanwhile the adult remain in the center of Hokkaido (mountains).
The bunch of coordinates received today has brought exciting news. The young eagle was heard from again and sent a signal from the Baklan Cape of the Sakhalin Island, some 25 km north of his previous transmission. So, it did not decide to cross the open sea after all.
The adult remains in the middle of the Hokkaido (last transmission on 20 January), close to the areas it visited last winter.
