Sadly it looks like our last Cuckoo to make his crossing may have left it too late and we think Jack may have died. Recent locations show him in the same place as on 9 October. Looking more closely at the last signals received it seems that Jack actually stopped 200km NW of his final (current) location, for a day at least, before moving on.
The movement that might have ended abruptly was actually an onward movement after his first post-desert stop. If he has died, it's a good illustration of the cost of leaving the desert crossing so late - 2 months ago the area would have been very good for him, teeming with insects. But now it is drying out, as evidenced by the other cuckoos all having moved south.
